Heavy rain and hail (often less than 3/4-inch) accompanying widespread convective activity through Interior Central California late inthe afternoon and early evening of Saturday, April 7th, caused extensive damage to agriculture. Although isolated severe hail swathsoccurred and some were defined as technically non-severe, widespread heavy rain in conjunction with the hail damaged young fruit,grape, grain, and early planted cotton crops in several counties. The crop damage figures should be considered approximate becausethey are in conjunction and need to be summed with the crop damage figures reported for the April 4th freeze and frost event throughmuch of the same area.

Post storm analysis and evaluation yielded a 0.3 mile swath for a small F0 tornado through an older, residential neighborhood ofClovis, CA, 2 miles northeast of the Fresno Air Terminal. No injuries were reported with damage essentially limited to uprootedtrees, roof, small structure, and fence damage. Confirmation was determined by damage evidence and eyewitness reports.Interesting Note: One of the uprooted trees was a replacement from its predecessor damaged from the 1980 Fresno Air Terminaltornado!

Storm analysis and survey concluded that two straight line wind events occurred within a few minutes of each other in and around theCalifornia State University Campus in North Fresno. An initial gust from the southwest was followed closely by another from thewest-northwest. Large trees and roof damage was noted in clearly distinct damage areas. Some evidence existed for rotation bydebris but the likely culprit was some gustnado action on the leading edge of the outflows. Convection was noted on radarimmediately to the south and west at the time of the event but note overhead. The largest damage track was close to 0.75 miles andup to 1/8 mile wide.

During the first week of April a strong storm system fanned warm temperatures northward accelerating the snowmelt across theupper Mississippi river basin. Another storm system mid month sent even warmer temperatures surging northward along with severethunderstorms and heavy rain. The prolonged abnormally warm conditions resulted in rapid snow melt and produced near recordflooding over counties bordering the Mississippi River. Additional heavy rain fell over the headwaters of the Mississippi during thethird week of April. This added streamflow led to secondary crests over Minnesota, Northern Iowa, and Wisconsin, and helped toprolong the flooding, or broaden crests on the Mississippi from the Wisconsin/ Illinois border to counties north of St Louis Missouri.Strong winds accompanying the storms forced water over sandbag dykes and levees causing additional damage. At Moline additionalflooding occurred when backwaters from the Mississippi caused flooding at the mouth of the Rock River. To aid with floodpreparations, the Illinois Department of Transportation distributed and pre-positioned 692,000 sandbags to flood prone areas.Communities impacted by flooding called upon the Illinois Dept of Corrections, the Illinois Dept of Public Health, the Illinois Deptof Natural resources, and hundreds of volunteers to help with sandbagging and flood fighting efforts. By late month 8 Illinoiscounties had been declared disaster areas, with damages and related flood costs estimated to be several million dollars. Floodingcontinued along the Mississippi River from East Dubuque IL to Quincy Il into May.

Synoptic and mesoscale conditions on April 9th, 2001...

A stalled frontal boundary extended from northern Ohio back west into northeast Missouri with a developing surface low pressurewave near Quincy, Illinois monday afternoon. This wave intensified late in the afternoon as a shortwave trough embedded within thesouthern periphery of a significant upper jet maxima of 120 knots over Minnesota pulled out into the upper Midwest. Wind profilersat both Wolcott, Indiana and Winchester, Illinois indicated rapid backing low level winds and increasing speed convergence around2500 feet coincident with rapid convective initiation along the frontal boundary from Logansport to Rensselaer.

Storms rapidly intensified with CAPES (Convective Available Potential Energy, a measure of parcel buoyancy) south of the frontalboundary up to 3000 J/kg. In addition...several storm scale mergers were observed with a left over outflow boundary from priorconvection. Thunderstorm intensification was very rapid owing to the large amount of instability in place along and south of aMonticello to Muncie line. Deep layer shear to 50 knots was more than sufficient for supercell development. Indeed most stormsalong the outflow boundary exhibited strong rotation...mainly at mid-levels but two storms in particular that moved across Cass,Miami, Grant, Blackford and Jay exhibited persistent, deep rotation with several funnel cloud reports but failed to produce anyconfirmed tornadoes. However...these two storms did produce prodigious large hail...up to 4.5 inches in diameter just north ofHartford City.

A large tree and several limbs were blown down in Granger leaving 2600 people without power for a time. An additional 2900people were without power across the county with several tree limbs blown down on power lines.

Thunderstorm Wind (G75) 30K0005Redding 1440CSTThe seasons first severe weather event took place during the afternoon of the 5th. A strong upper level low pressure system over thesouthwest was in place with a broad area of south winds across the Plains. Moisture from the Gulf of Mexico streamed north witsurface dew points in the 60s to low 70s from central Iowa south to the Gulf Coast. The moisture was fairly deep with 850 Mb dewpoints in the 10 to 15 degree C. range as well. Thunderstorms formed to the southwest of the Des Moines CWA in an area of strongTheta-E advection. The storms moved into southwest and south central Iowa during the afternoon before sinking south into Missouriby early evening. Three quarter inch diameter hail occurred in Adams and Ringgold Counties as the stronger storms movedoverhead. In addition, high winds occurred in Ringgold County. Several large trees were downed by the high winds. In addition,structural damage was reported to a few buildings in the town of Redding.

A warm front extended east from a developing surface low over thesouthwest U.S. Thunderstorms erupted during the late night hours on the nose of the low level jet. Dew points were in the 60s to low70s to the south of the front. Thunderstorms moved into central Iowa, producing hail and high winds. Winds of 70 MPH werereported in Guthrie County in the Panora and Guthrie Center areas. Winds downed a tree on top of a garage in Guthrie Center. Hailwas common with the storms. There were numerous reports of pea to marble size hail. Nickel size hail covered the ground atGuthrie Center and in Johnston. As the storms moved east, hail of three quarter inch diameter fell in Ankeny.

The storm mentioned in the previous narrative continued to track northeast during the day on the 6th. As the evening progressed, thestorms system "bombed" out as a strong negatively tilted trough aloft moved across the central U.S. Warm and dry air moved inaloft, tending to cap the convection during the afternoon. By evening the colder air begin to wrap around the surface low pressure asrapid deepening took place. Thunderstorms erupted again north of the warm front as it lifted north across the state. High winds werethe result as a very strong wind profile was in place. High winds caused damage on a farm near Lakota in Kossuth County. At leastone grain bin was blown over and several others were damaged. A tree was downed on a house in Worth County in Manly. Therewere numerous reports of damage around the county caused by the winds and broken branches. A semi-tractortrailer was overturnedby the high winds on Interstate 35 near the Joice exit. Fortunately the driver was not injured.

IOWA, Centralintensified rapidly as it moved across the central U.S. with the central pressure falling below 980 Mb during the day on the 7th. Avery strong pressure gradient resulted. Winds increased during the predawn hours of the 7th as the gradient tightened and the dry slotmoved over the state. Winds gusted to as much as 61 MPH by shortly after 0400 CST in Carroll. During the day on the 7th,sustained winds increased to 35 to 45 MPH across the state by shortly after sunrise. The winds caused at least minor damage in mostareas of the state. There were numerous reports of tree limb damage and objects being blown around. The strongest winds were overthe north and west portion of the Des Moines CWA. A few of the wind gusts include an 83 MPH wind gust near Mason City. Atone point reports indicated winds were sustained at 55 MPH with gusts to 83 MPH. Trees were toppled, street signs were blowndown, and shingles were removed from many buildings. Several semi-tractortrailer trucks were blown over on Interstate 35 by thestorm force west wind. An official wind gust of 82 MPH was received from Storm Lake, just outside of the Des Moines CWA.Eighty MPH winds were reported in Emmet County at Wallingford. One to two foot diameter trees were uprooted. In addition, roofdamage was reported as well as numerous reports of grain bins being blown over. In Wright County, 74 MPH winds were recordedat the Eagle Grove Airport. A section of the hanger roof was blown off by the winds there. Wind gusts of 70 MPH were receivedfrom both Algona and Wesley in Kossuth County. In Worth County, 70 MPH winds blew a three foot diameter tree onto a squad carin Northwood. Farther to the west, winds of 69 MPH were reported at Denison in Crawford County. Wind gusts in the 60 to 70MPH range were too numerous to mention. Damage was widespread over the northwest half of the state ranging from fallen trees toshingle damage and blown over outbuildings. Over the southeast half of the state damage was not as widespread with most being inthe form of broken branches, shingle damage, and a few fallen trees. Two people were injured in Thompson in Winnebago County.High winds toppled a camper in a recreational park in town. The camper toppled end over end with the two occupants treated andreleased in local hospital. Two others were injured in Hancock County as winds blew a car off of the road near Crystal Lake.

2100CST0300CST

The first significant rainfall of the month affected much of the Des Moines Hydrologic Service Area (HSA) on the 5th as scatteredshowers and the seasons's first thunderstorms moved across the area. The 24-hour isohyetal map showed a chaotic pattern as 0.50 to0.75 inches fell across west central Iowa, mainly in the North Raccoon River basin. Rains in excess of a half-inch fell along thesouthern border of Iowa. Less than 0.10 of an inch fell over northwest and south central parts of the HSA, while a broad area ofaround 0.25 inches fell from just north of Des Moines northeast into the Cedar basin. Early on the 6th a few severe storms developedover west central Iowa and moved just north of Des Moines. Hail and brief heavy rain (0.68") accompanied the storms as they passedover the Des Moines WFO in Johnston. Numerous Flood Statements and several Flood Warnings were issued on the 7th in responseto pervious rains and the forecast rainfall for the next 24 hours. Heavy rains did develop across much of Iowa on the 8th, with thehighest amounts over the southwest and central portions of the HSA: The cooperative observer at Blockton picked up 2.45",Beaconsfield 2.07", and the Des Moines Airport ASOS 1.59". Widespread severe weather also occurred on the 8th into the earlymorning hours of the 9th and this was combined with heavy rainfall. Flash Flood Warnings were issued for eight counties, includingRinggold, Decatur, Taylor, Wayne, Dallas, Polk, Marshall and Story counties as radar and satellite estimated rain of up to 4 inchesfell in parts of the affected counties. Renewed rains developed on the 10th and began an extraordinarily wet period, especially fornorthwestern parts of the HSA. At Estherville, in the upper Des Moines River basin, a 2-day total of 2.79" fell on the 10th and 11th.These rains drove the West Fork Des Moines River well above Flood Stage from the Minnesota River downstream to its confluencewith the mainstem Des Moines River at Humboldt. Estherville (ESVI4) crested at 13.38 feet on the 12th, which was the highest levelsince 1993 (15.38 ft.) and the 8th highest on record. At Emmetsburg, the river crested on the 14th at 12.31 feet, also its highest levelsince 1993 and 10th highest on record. Snowmelt flooding in the Cedar and Iowa basins peaked about mid-month, with the Cedar atWaterloo (FS = 12) reaching 16.59 feet on the 15th and Iowa at Marshalltown (FS = 15) 15.86 feet on the 17th. None of the floodingwas particularly serious. The second half of April saw a much drier weather pattern over much of central Iowa, although moderate toheavy rains fell across much of the region from April 21-22. The heaviest rains were again over the northwest sections of the HSA,which maintained high river levels, but not reaching the levels seen a week earlier. River levels fell through the rest of the month.

Following the passage of the powerful storm system earlier in the weekend, another round of severe weather was on tap for the state.The cold front from the previous storm did not move all that far to the south of Iowa. As a result, warm and moist air was able tomove north into Iowa rapidly. A warm front lifted into southern Iowa during the late afternoon hours, sending temperatures into the80s over parts of southern Iowa. Dew point temperatures jumped into the low to mid 60s. The atmosphere became very unstablewith thunderstorms developing along the front. Most of the storms were associated with the warm front itself, though a mesoscalefeature moved along the front setting the stage for an additional like of thunderstorms that developed north to south in south centralIowa. The main feature with the storms was hail. There were numerous reports of hail ranging from nickel size up to golf ball size.Several of the storms had well developed meso circulations associated with them. A few tornadoes resulted. Two of the tornadoeswere very small and only touched down briefly in Tama and Dallas Counties. The other tornadoes were stronger. One tornadotouched down in Decatur County near Leon. Two people were injured, one requiring hospitalization, as a mobile home wasoverturned by the gust front ahead of the storm itself. The second of the stronger tornadoes moved through Adams County. A trailerhouse was overturned and the roofs were removed from two sheds on a farm northeast of Mt. Etna. Thunderstorms produced veryheavy rainfall of one to two inches per hour over Ringgold County. Total rainfall approached 4 inches in less than 3 hours as stormsrepeatedly moved across the same areas. The rain caused flash flooding in the county. In one instance, Lotts Creek overtopped aroad southeast of Mt. Ayr, causing nearly $50,000 in damage as the road washed out. As the storms moved through Decatur County,lightning stuck a house in Garde Grove. The house was set on fire, but it was not detected for several hours after the lightning strike.The house was destroyed and completely burned to the ground.

During the predawn hours of the 10th, a strong area of thunderstorms developed over central Nebraska. This area held together as itmoved through eastern Nebraska into Western Iowa. The complex was moving into an area of lower quality air and tended to weakenas it moved into the state. The cluster did make it as far as central Iowa before falling below severe levels. As the storm moved intothe Des Moines CWA, the severe event was that of hail. One inch diameter up to golf ball size hail fell out of the strong supercell.The storm weakened as it moved east of Adair County.

In the wake of the strong thunderstorm cluster that moved through the area during the mid day hours, another round of thunderstormslifted north out of Kansas and Missouri. A strong push of warm and moist air took place with severe thunderstorms developing onthe nose of the low level jet stream. Iowa was on the cool side of the frontal system and as a result the severe thunderstorms had adifficult time surviving. One cluster of storms produced hail from nickel up to golf ball size in Cass County before it weakened.

A very powerful storm system moved through the southern Rockies during the night of the 10th and early morning of the 11th.Intense surface low pressure formed over western Kansas with a central pressure by sunrise on the 11th of 977 Mb. The weathersituation was very dynamic with 500 Mb winds over 100 kts and a very sharp dry punch clearly visible on the satellite pictures.During the day the warm front that extended east from the low reached into southern Iowa, then extended eastward. There were twothings that occurred during the day. The first was a very strong supercell that formed over northern Missouri during the morning.This storm lifted north-northeast at about 50 kts into Iowa, producing a long track tornado with a path extending nearly all the way toDes Moines. During the afternoon the warm front surged north with the northeast progression of the surface dry line. Dew pointsrose into the mid 60s to the south of the warm front across much of the southeast half to two thirds of Iowa. Surface temperatures inthese areas reached the 60s north, with 70s south. With the atmosphere primed, the dry line began to move into Iowa. Dew pointtemperatures behind the dry line were in the 30s with southwest winds of 30 to 50 MPH. A broken squall line formed on the nose ofthe dry punch and became severe quickly. The storm cells themselves were not all that large, but nearly every cell along the line didcarry a mesoscale circulation. There were several tornado touchdowns as the line lifted north as well. The primary severe weatherduring this even was the tornadic nature of it. There were reports of wind and hail, but everything considered these reports werepretty scattered. There were very few reports of wind and hail with the first supercell as it lifted north out of Missouri. One inchdiameter hail was reported in Ringgold County east of Redding. Reports of winds and hail were more frequent with the second lineof thunderstorms. There were numerous reports of hail up to marble size with this line, however there were not all that many reportsof hail larger than that. A few reports of three quarter to one inch diameter hail were received from Marion and Polk Counties. Themost significant hail occurred in northeast Iowa in Butler County. Golf ball size hail fell in the town of Parkersburg as the line passedover the city. There were more reports of wind with the second round. Nearly all locations reported winds of at least 50 MPH as theline passed overhead. Scattered reports of winds of 70 to 85 MPH were received. Wind damage occurred in Boone County as highwinds downed power lines and downed outbuildings north of Ogden. The greatest wind damage occurred over northeast Iowa inBlack Hawk and Franklin Counties. A building was blown off of its foundation and onto an adjacent road southwest of Hampton inFranklin County. A roof of a barn was damaged and a grain wagon was tipped over northwest of Hampton. Roof and house damagewas reported over parts of Black Hawk County as well. Five injuries occurred in Warren County at Carlisle when winds of around 65MPH toppled a school bus. Twenty one children were on board the bus when it overturned with 5 treated for minor injuries. Spottydamage was reported around the greater Des Moines metropolitan area. Several tornadoes occurred with this system. The most

IOWA, Centralsignificant tornado entered southern Iowa around mid day. This tornado reached minimal F3 intensity just east of Mt. Ayr (RinggoldCounty). Property damage is estimated at over $500,000 in Ringgold county alone. Across the Des Moines area of responsibility, atleast 15 homes were destroyed, and 60 residences were damaged as around a dozen tornadoes touched down. A supercellthunderstorm moved north from Missouri into southern Iowa late in the morning of April 11. The storm produced a tornado innorthern Missouri and crossed into Iowa in Ringgold County. The storm, and tornado, moved north through Ringgold County with acontinuous damage path half way through the county. The damage path continued north through northern Ringgold County,southeast Union County and into northwest Clarke County. In this area, the path was not continuous. Based on damage reports, thetornado continued to produce occasional damage in Madison County. Chaser reports indicate the tornado had a multi-vortex structureas it moved through Ringgold and Union Counties. The last reported sighting was in northern Polk County where a brief touchdownwas reported with no damage. The storm likely produced one tornado from the Missouri border to Madison County with anintermittent damage track. Damage in Ringgold County was severe with initial estimates around $1 million. The county was laterdeclared a federal disaster area by President Bush. A second tornado briefly touched down in northern Polk County. The touchdownin Polk County was indeed a separate tornado. Even though the tornado was from the same parent cell, the system had occluded andwas in the process of forming a new tornado as it passed over the western part of the Des Moines area. Reports from this tornadoindicate that at least 9 homes were damaged or destroyed, one business destroyed, and a school building damaged. In addition tolosses to homes, one farmstead was hit with considerable damage and some livestock damage. A series of tornadoes formed on theheels of the supercell tornado as the dry line pushed into the state. Most of these were brief touchdowns, however the storms weremoving around 60 MPH. Three tornadoes touched down in Boone County. The most significant tornado touched down north ofOgden. It produced a 3 mile long track up to 1/8 mile wide. Farm site hit along highway P70. Barn and grain bins destroyed,knocking out windows in house. Otherwise only minor damage to house. Debris scattered 1 mile to next farm site where there wasminor damage to many buildings. Track continued north-northeast across highway E26 into the campground at Don Williams Lake. Astorage building was destroyed, several trees downed, plus outhouses, picnic tables and signs were damaged. The damage trackdissipated on the northeast side of the Don Williams Recreation Area. There were several brief touchdowns with relatively minordamage in Guthrie, Greene, and Hamilton Counties. A stronger tornado touched down in southeast Black Hawk County, causingsignificant damage to two homes in the La Porte City area. The most serious tornado in terms of loss of life occurred in WapelloCounty. A tornado developed in rural southern Wapello County, a mile southwest of Agency, Iowa, around 1600 CDT, onWednesday, April 11. The tornado path was 50 to 100 yards wide with sporadic touchdowns toward the north-northeast for the next6 miles. Survey responses indicated that the duration of impact at any one location was only 15 to 30 seconds as the tornado quicklymoved through Agency and over farms at a 60 mph horizontal movement. The Odd Fellows Lodge in Agency was destroyed, andover 50 residences were damaged. Two women inside were killed, three people injured and three people had no injuries. As thestorm moved through Agency, a garage was lifted and carried about 100 meters off of its foundation. The car inside was twisted andcovered with debris. In another incident, one house was hit by the tornado causing damage to the house. The family dog was in thedog pen at the time. The tornado lifted the pen and twirled it through the air. The dog pen was deposited some distance downstreamand what was truly amazing was the fact that the dog was uninjured. Following the tornado, U.S. Highway 34 was closed for 2 hoursin order to removed debris from the highway. Governor Tom Vilsack visited the area during a storm survey. The governor spokewith Brenda Brock of the National Weather Service, Ellen Gordon, Administrator, Iowa Emergency Management Division,emergency management personnel (fire department, law enforcement, mayor) and the public. A proclamation for emergency disasterassistance was signed.

A complex and active weather pattern was in place over the upper Midwest. A warm front lifted north across the state during theprevious day, allowing a strong surge of moisture to flow north from the Gulf of Mexico. Temperatures rose into the 70s to low 80sas surface dew point temperatures rose into the upper 50s and 60s across the state. By the early evening hours, a frontal boundaryextended from near Sioux City east-northeast into the northeast corner of the state. Thunderstorms fired along this front and becamesevere during the evening. These storms produced very heavy rain with numerous reports of hail. For the most part, the hail wasaround an inch in diameter with the storms. There were a few reports of hail up to the size of golf balls however. Reports of golf ballsize hail were received from the Ringsted area of Emmet County, and also from the Fraser area of Boone County. Two things weretaking place during the evening. While the thunderstorms were firing along the warm front over northern Iowa, a strong low pressuresystem was racing out of Colorado. CAPE values across northeast Kansas into Iowa were in the 2000 to 3000 J/Kg range as a dryline extending south from the low approached the area. Strong thunderstorms developed over northeast Colorado and raced eastacross Nebraska and Kansas. The thunderstorms took on a bow echo configuration as they headed across the Plains at more than 60MPH. High winds raked Nebraska and Kansas before moving into Iowa. There were numerous reports of winds of 60 to 80 MPHas the line advanced across the west half of Iowa with numerous reports of trees and power lines downed. As the storms movedthrough Carroll County, several outbuildings were destroyed in the Templeton area. Machine sheds were totally destroyed in Adair

IOWA, CentralCounty by the high winds. Further northwest, in Greene County, a barn was flattened north of Scranton. Damage continued as thestorms continued east with reports of outbuildings damaged or destroyed toward Hamilton County. One of the most damaging eventsof the night took place late in the storm cycle. The storms turned into wind producers. High winds hit the Lake Mills area inWinnebago County for example. A barn and several sheds were destroyed by the winds around 80 MPH. As the storms moved intoHardin County, a microburst occurred west of the Iowa Falls area with winds estimated around 85 MPH. A tornado touched downbriefly in the community of Alden, causing considerable damage in the town. The tornado touched down in two locations of thetown, damaging several buildings four blocks apart. Concrete blocks were picked up and thrown 50 to 75 yards and roofs of theaffected buildings were strewn one quarter to three eighths of a mile downstream. One business was damages with estimated damagearound $180,000. On a farm at the edge of town damage was estimated at $100,000. Numerous trees were downed on Highways491 and D15, blocking travel in the area. Shortly after this event occurred, the storms weakened and continued moving northeast.

An intense low pressure system lifted northeast out of the Rockies, across northwest Iowa and on into the upper Great Lakes duringthe afternoon of the 22nd into the 23rd. The dry slot lifted north ahead of the low and passed over Iowa during the early morninghours of the 23rd. Within the dry slot winds of 70 to 85 MPH were common just a few thousand feet above the surface. Shortly aftersunrise, a narrow band of showers formed over northeast Iowa. As the showers moved through northeast they produced very gustywinds. In Black Hawk and Bremer Counties, winds were in the 65 to 70 MPH range. Damage was reported around the two counties.Three miles northwest of Washburn in Black Hawk County a farm shed was completely destroyed. In Bremer County, a farm shedwas destroyed by the winds near Tripoli and damage to power poles was reported in the Readlyn area. At the onset of the highwinds a very narrow squall line developed. Actually, forming near the cold core of the upper low pressure area, convective tops werevery low with little if any lightning associated with them. A tornado touched down briefly in Black Hawk County near Gilbertville.One house was damaged and power was cut to three others. The tornado lifted quickly and didn't touch down again until it was eastof the Des Moines CWA.

Event summary for 4/7/01: (For additional details, see individual entries for the date)A very strong low pressure center tracked N/NE from Nebraska through Minnesota. The tight pressure gradient produced by thesurface low, along with daytime heating, created very strong winds across eastern Iowa and northwest Illinois through much of theday, beginning around 8 am and ending around sunset. A southwest wind was sustained at 30 to 35 mph, with gusts from 50 to 55mph. There were a few isolated wind gusts of 58 to 60 mph across eastern Iowa (see individual reports above), but most of the arearemained below High Wind Warning criteria, which is sustained speeds of at least 40 mph (34 knots) for an extended period of time,or a gust to at least 58 mph (50 knots). Wind damage and power outages were widespread throughout the area, as high winds blewtrees down on power lines, or snapped the power poles themselves. According to newspaper accounts, an estimated 20-thousandpeople lost power across eastern Iowa and northwest Illinois. Numerous trees and power lines were downed, and shingles and sidingwere blown off buildings and homes. The high winds blew a power line down at a rural Johnson county home, which led to a firethat destroyed the structure. A downed power line also caused a fire that damaged a funeral home in Buchanan county. Lawenforcement in eastern Iowa reported two accidents resulting from the high winds. There were no injuries.

Snowmelt flooding, starting in March, continued across eastern Iowa with the Wapsipinicon and Iowa rivers above flood stage at thestart of the month. During the first week of April a strong storm system fanned warm temperatures northward accelerating thesnowmelt across the upper Mississippi river basin. Another storm system mid month sent even warmer temperatures surgingnorthward along with severe thunderstorms and heavy rain. The prolonged abnormally warm conditions resulted in rapid snow meltand produced near record flooding over counties bordering the Mississippi River. Additional heavy rain fell over the headwaters ofthe Mississippi during the third week of April. This added streamflow led to secondary crests over Minnesota, Northern Iowa, andWisconsin, and helped to prolong the flooding, or broaden crests on the Mississippi from the WIsconsin/ Illinois border to countiesnorth of St Louis Missouri. Strong winds accompanying the storms forced water over sandbag dykes and levees causing additionaldamage. Communities impacted by the flooding called upon the National Guard, prison inmates, and hundreds of volunteers to helpwith sandbagging efforts. By late month 10 Iowa counties had been declared disaster areas, with damages estimated over 4.7 milliondollars. Other preliminary estimates showed 40 homes had been destroyed, 62 homes suffered major damage, 1,516 homessustained some damage, and 129 businesses were closed due to flooding. Snowmelt flooding also impacted the Cedar River as waterfrom Minnesota and the upper Cedar River basin moved downstream. Flooding continued along the Mississippi River from DubuqueIA to Keokuk IA into early May.

A trained storm spotter reported a brief tornado touchdown. There were no injuries and no damage reported.

Summary for Independence tornado event on 4/23/01:

The exit region of a vigorous mid-level jet streak helped create deep layer convergence in eastern Iowa along a surface cold front,during the morning of 4/23/01. The atmosphere was only marginally unstable, but shear values were very high. A study of the eventat the NWS in the Quad Cities suggest that the tornado was non-descending in nature, with the rotation originating near the surfaceand building upward. Spotters reported no lightning or thunder with the tornado, which the local study suggests indicated rapiddevelopment during the initial stages of the storm. There was no evidence from radar data that a tornado occurred. The tornadotouched down near the middle school in southwest Independence, and tracked through the west central and north central parts of thecommunity, before lifting 3.5 miles northeast of Independence. The tornado path was continuous, 5 miles long and 1/8 mile wide.The tornado was rated F1 on the Fujita scale following a NWS Survey. Three people suffered minor injuries from flying debris, andwere treated at the local hospital. Emergency management officials estimated the tornado caused a total of $ 1 million in damage. Atotal of 31 homes were damaged, two severely. 20 businesses and 20 vehicles were also damaged.

The combination of snow melt runoff and heavy rains caused the Mississippi River to rise to levels second only to the all-time recordflood of April 1965. At Lansing (Allamakee County), the river crested at 19.9 feet on April 21. Further downstream, McGregor andGuttenberg (Clayton County) crested at 23.8 feet on April 20 and 21.6 feet on April 22 respectively. Considerable damage was doneto homes and businesses by the high water, especially in the small towns of Marquette and Guttenberg (Clayton County). Overalldamage costs due to the high water were estimated between 4 and 5 million dollars. This resulted in Allamakee and Clayton Countybeing eligible for federal disaster relief funds. Even though the river began falling during the latter part of the month, water levelsremained above flood stage until early May.

The farmstead sustained damage to outbuildings and trees. The home was spared from major damage.Another weak tornado started on the south side of Plainville and traveled up US highway 183 and then northeast to a modular homemanufacturing plant. Several homes in production were damaged. Other homes along the path had roof or window damage. Threeother tornadoes occurred in Osborne county. The first, on the west side of the county, damaged outbuildings and trees along its 9mile path. A short lived tornado near the junction of US highway 24 and Kansas Highway 181 hit an abandoned gas station. Oldtanks and concrete blocks were littered about for nearly a mile to the northeast.

Extremely intense and deepening low pressure moving from northwest Kansas across Nebraska to Iowa produced widespreaddamaging 43-65KT southwest winds across central and south-central Kansas from late morning thru early evening. In extreme cases,buildings were completely unroofed. Among the casualties in this category were a restaurant in Arlington (Reno County), a recyclingcenter in Newton (Harvey County), and two homes in southwest Butler County. Other extensive roof damage included the City Hallin Benton (western Butler County), an elementary school in Cottonwood Falls (Chase County) where half of the roof was blown off,a horse barn in Eureka (Greenwood County) where nearly half of the roof was blown off and the west wall partiallly dislodged, and inPilsen (northeast Marion County) where the community center lost most of it's roof. In addition, roofs were blown off sheds andshingles peeled from countless homes.

Driving was especially dangerous as least half a dozen tractor-trailers were overturned resulting in injuries to two people. One injuryoccurred 3 W Augusta in western Butler County when a tractor overturned and the driver was thrown. One man was injured on K-96about 10 W Wichita when his tractor-trailer overturned. A total of five tractor-trailers overturned on I-235 in Wichita and on K-96alone. One truck overturned on Highway 56 just north of Marion in Marion County.

Damage to trees, power lines, and power poles was widespread and occasionally started fires. A few areas were without power thruthe following morning. In addition, windows were blown out and many signs either blown out or blown over.

Law enforcement, emergency managers, trained spotters, broadcast media, and area newspapers all contributed greatly to this report.

A stationary front lay west-to-east across northern Indiana and Ohio. Temperatures north of the front in southeast Michigan wereonly in the 40s. Despite this, warm moist air poured into the region aloft, providing a source of elevated instability. A cluster ofshowers and thunderstorms strengthened as it moved east into southeast Michigan during the morning. A number of these producedlarge hail, making for an unusually chilly severe weather episode.

Like the day before, a front was nearly stationary across Indiana and Ohio. Again, enough instability was found aloft forthunderstorm development, though the environment was more favorable for storms to the south and west of southeast Michigan. Astorm developed in Hillsdale County, Michigan toward 3 am EDT. The storm tended to weaken as it moved into Lenawee County,but not before producing dime sized hail in the western part of the county.

A strong cold front moved across southeast Michigan in the morning. Strong winds were observed across much of the area after thefront went through. In a few spots, the winds reached high wind criteria:Willow Run Airport measured a 61 mph wind gust.Several communications towers were blown down in Monroe County.Several trees and a large barn were destroyed on a farm near Almont.Across the rest of southeast Michigan, most of the damage comprised of isolated trees, large limbs, and power lines being downed, aswinds gusted around 50 mph at times. An indirect fatality occurred in Detroit, where a 9 year old boy came in contact with a fallenpower line, and was electrocuted. In Ann Arbor, a 7 year old boy suffered minor injuries when a soccer net was blown over onto hishead. The Detroit Lions practice dome in Pontiac collapsed in the strong winds. In Lake Orion, a tree downed at a dealershipdamaged or destroyed 8 new cars. Nearby in Oxford, a cinder block wall inside a school bus garage was toppled, and shingles wereblown off a school roof. A freeway sign was downed onto 11 Mile Road in Royal Oak. In Warren, a golf dome was destroyed. Anapartment complex in Chesterfield Township (Macomb County) saw a brick facade sheared off; the bricks landed on a row of gasmeters, and the building was evacuated until the gas could be shut off.

Many rivers remained well above floodstage into mid-May (see May 2001 Storm Data). The crest at Montevideo on the Minnesota River was the second highest ever, only1.3 feet lower than in 1997. The crest at Stillwater on the St. Croix River was the second highest crest ever, only 1.8 feet lower thanin 1965. The crest on the Minnesota River at Henderson came within one half foot of its record level that was set in 1965. TheMississippi River at St. Paul, Hastings, and Red Wing crested at its third highest level ever, lower only than during the floods of 1965and 1969.

Numerous roads and bridges were closed, millions of sandbags used, and approximately 200 homes and businesses were partiallysubmerged with flood waters. About 100 homes and businesses were damaged beyond repair. Part of the Marsh Lake Damsouthwest of Appleton (Swift County) eroded on April 7, but officials shored it up with 9000 tons of rock and gravel. Three fatalitieswere attributed to the flooding. Two boys (ages 5 and 8) in Olivia (Renville County) were playing on top of melting snow along adeep drainage ditch. They died when the snow collapsed into the drainage ditch with its torrential flow. The other fatality came whentwo men drove around a barricade on Highway 101 at Shakopee (Scott County) and drove into the Minnesota River. One 19 year oldman died and the other was injured.

The headwaters of the Red River received the most snow over the course of the winter. Snow water equivalents of 4 to 5 inches weremeasured from the snowpack over this area. As the snowmelt progressed through early April, several heavy rain events occurred.The first, on the 7th of April, brought widespread rainfall amounts of 1 to 2 inches to the southern Red River basin. This rain fell ontop of the remaining snowpack, which resulted in faster rises on the Red, Ottertail, Rabbit, and Bois de Sioux Rivers. Both the Boisde Sioux and Ottertail Rivers crested at the same time in Wahpeton, something that hadn't happened in recent memory. This broughtthe first crest on the Red River at Wahpeton, 16.96 feet on the 9th. A second heavy rain event occurred on the 11th and 12th ofApril, with many locations south of Wahpeton-Breckenridge reporting 1 to 1.50 inches of rain. This led to a second crest atWahpeton on the 13th of 16.21 feet. As the Red contined to fall after this second crest, a winter storm event occurred on the 22ndand 23rd. This storm brought over a foot of snow to some locations in Wilkin county. As this snow rapidly melted over the nextcouple of days, it brought a third crest on the Red River at Wahpeton on the 26th at 13.88 feet. The 16.96 foot crest was the 5thhighest crest on record. 3 of the top 5 Wahpeton crests have occurred since 1996. As the snowmelt progressed across southernWilkin county, overland flooding caused major problems between the Rabbit and Ottertail Rivers. The town of Doran wasvoluntarily evacuated when the overland flooding threatened to overtake the town. 60 National Guard troops assisted the city ofBreckenridge during the flood. The rural roads suffered a great deal of damage from the spring flood.

A heavy rain event on April 7th brought a widespread swath of 1 to 2 inchesof rain to the Red River basin. This rain event, along with the snowmelt runoff, contributed to the crest of 36.69 feet in Fargo on the14th of April. This was the 4th highest crest ever at Fargo. Another rain event on the 11th and 12th, and a winter storm that brought7.9 inches of snow on the 22nd and 23rd, helped keep the Buffalo and Red Rivers high for nearly the whole month. Problemsdeveloped around Oakport Township in north Moorhead, where the Red River made islands once again out of the neighborhoodhomes. The US Army Corps of Engineers had to cut 2 sections of road to alleviate the flooding there. Many roads and bridges had tobe closed along the river. A main link to Fargo, the 1st Avenue North bridge, closed due to the high water. The Buffalo River atHawley and Dilworth stayed above the moderate flood level from April 6th to 17th.

2359CSTThe winter brought 45.3 inches of snow to the Grand Forks-East Grand Forks area, which is slightly above the average of 40 inches.Snow water contents across Polk county ranged from 1.5 to 2.5 inches. The snow over Polk county had melted by the 1st of April,and the snowmelt began to affect the rivers. Then, a heavy rain event occurred on the 7th, and brought 1 to 2 inches of rain to theRed River basin. The Red Lake River rose quickly after this rain event. In Crookston, an ice jam developed in Hewitt Park on thenight of the 9th, rocketing the Red Lake River to 26.38 feet. At its peak rate of rise, the Red Lake River jumped nearly 8 feet in 6hours. 60 National Guard troops were activated in Crookston and they helped evacuate several homes. The entire city waited for apossible evacuation order as they watched the river rise. U.S. Highway 2 had to be diverted, as the rising river closed the underpassin town. When the ice jam broke, the river quickly fell. As this water and other runoff made its way into the Red River, the level atEast Grand Forks peaked on April 12th at 44.80 feet. This 44.80 foot level was not in the top ten stage heights. Another rain eventfurther south on the 11th and 12th, and a winter storm on the 22nd and 23rd helped hold up the level on the Red River at East GrandForks through most of the month. East Grand Forks erected their new "invisible" flood wall for the first time. This closed Demersavenue in East Grand Forks. The point bridge was also closed between Grand Forks and East Grand Forks, due to high water fromthe Red River. Sunshine Terrace and its 48 occupants were temporarily evacuated, as the building now sits on the wrong side of thedike.

The winter brought a good amount of snow to the northern Red River Valley, which resulted in snow water contents of 1.5 to 2.5inches. The northern Red River Valley received less snow than the southern valley, which resulted in the snow cover disappearingfaster over the north than further south. A heavy rain event on the 7th brought widespread 1 to 2 inch rainfall amounts to the entireRed River basin. Another heavy rain event over the southern Red River basin on the 11th and 12th, and a winter storm that droppeda foot of snow over the southern Red River basin, helped hold the Red River level at Oslo near 37 feet from April 13th to 17th. Thisriver crest was close to the 5th highest ever.

Rainfall in the upper Mississippi River Basin hastened the snowmelt in Minnesota and Iowa. Although the flood wave attenuatedsignificantly by the time it reached the St. Louis Hydrologic Service Area (HSA), the flooding was still significant. Hannibal, MOreached the 9th highest stage on record, hitting 23.3 feet (flood stage 16) on April 28. Despite the fact that the stages were fairly high,damage was limited. Only 4 businesses sit outside Hannibal's flood levee. The rest were bought out and removed after the flood ofrecord in 1993. Most land flooded was either agricultural or land that was reverted back to natural floodplain after previous floods.

The flooding on the Mississippi reached the Ste. Genevieve County area on April 26. The flooding was limited to low-land floodplainand agricultural areas.

Prolonged flooding affected several states bordering the Mississippi River when storm systems fanned abnormally warm airnorthward. The warm air coupled with heavy rain from severe thunderstorms caused a deep snowpack over the headwaters of theMississippi to melt rapidly. Near record flooding occurred over sections of Minnesota, Wisconsin, Iowa, Illinois, and Missouri.Additional heavy rain falling over the upper reaches of the Mississippi prolonged the flooding and lead to a broad crest. Highwaysand roads over Iowa and Illinois were closed due to flooding and 18 counties in these states were declared disaster areas with damageestimates in the millions. In Clark County the Missouri Department of Transportation closed U.S.136 and U.S. 61 highways nearAlexandria for several days and rerouted traffic through St. Francisville.

As intense low pressure tracked from Kansas into north central Nebraska, south or southwest winds of 45 to 65 mph developed overeastern Nebraska and western Iowa. As the low moved north of the region, these winds became west or northwest across the area.Although the wind began increasing over the region Friday evening 4/6/01, they were the strongest from around midnight CDT4/7/01 lasting until early evening on the 7th, with the peak from midnight through 300 am. Most reporting stations, either Asos,Awos or other, had sustained winds of 40 to 50 mph. Stronger measured wind gusts included, 64 mph at Tekamah and the ValleyNWS, 63 mph at Lincoln and Fremont, 60 mph at Norfolk, 58 mph at Harlan, Iowa, 56 mph at Beatrice, and at least 50 to 55 mphgusts at Columbus, Millard, Omaha Eppley Airfield and Clarinda Iowa.

The strong winds caused areas of roof damage, most extensive in far northeast Nebraska, overturned a few semi-trucks, toppled trees,destroyed weaker farm out buildings, did minor structual damage to more well built buildings, and also damaged a few street andadvertising signs throughout the region. Although the damage was not widespread, there was scattered damage in almost everycounty in eastern Nebraska and southwest Iowa. Among the most severe damage reported was to a church steeple in west Omaha inwhich the top 25 feet or so was partially toppled. Also a tree was knocked through a home in Omaha, and a long section of copperroofing was torn off part of the Nebraska Capitol Building in Lincoln. There was also major roof damage to the High School inPender as well as at Dana College in Blair. Estimates of damage to the two schools alone were around $40,000 to $75,000 each. Hundreds to thousands of customers were without power for a while in Lincoln and Omaha and probably smaller communities aswell.

A 5 to 15 minute hail storm hit the Omaha, Council Bluffs and Bellevue area causing extensive auto and roof damage. The hailcovered the ground to several inches in some locations with most stones in the 1/2 to 1 1/2 inch range, although some were larger.From central into downtown Omaha, as the hail fell the visibility was lowered to near zero and the hail drifted like snow and shovelswere used to clear some sidewalks. An elderly Omaha woman was injured with some cuts and bruises from the hail when she wascaught outside.

According to State Farm Insurance agents, the storm was the costliest hailstorm in the Omaha area at least since the late 1980's andpossibly ever. State Farm estimated that there would be 100,000 claims in the Omaha Metro area. Most of the larger hail spared thenorthwest sections of the Metro area.

Two large hail producing thunderstorm cells tracked across the greater Omaha area this day, one across Douglas county and the otheracross Sarpy county. The storm that moved across Douglas county began producing large hail around Yutan, in Saunders county justto the west of the Douglas county line. The cell tracked across Elkhorn and then hit the western portions of Omaha with hail up togolfball size. The hail decreased in size to around 3/4 inch by the time the storm reached the eastern parts of the city. The majorityof hail damage from the storm was in a 2 or 3 mile wide west to east strip centered on Blondo Street beginning west of 156th Streetin far western Omaha and ending around 40th street in the east central part of the city. Damage included roof and skylights alongwith vehicles. Since the storm occurred in the late evening, and many vehicles were in garages, vehicle damage was not as severe aswhat was recorded with the hailstorm that hit Omaha earlier in the month.

As a cold front approached from the west, scattered thunderstorms developed during the late afternoon. Some thunderstorms becamesevere and produced dime-sized hail early Monday evening across southern Nassau County. Frequent lightning and heavydownpours also accompanied these thunderstorms. Lightning was responsible for destroying a home in Rye New York on ThistleLane at approximately 9:30 PM EDT. The lightning reportedly struck a floodlight located in a tree adjacent to the home, and thentraveled through the wires and into the walls of the house. This triggered a fire, which subsequently destroyed the home.

The thunderstorms moved east, out of southeast New York by late evening.

The combination of heavy rains and rapid snowmelt resulted in excessive water buildup in the caves underneath SharonSprings, Schoharie County. Excessive pressure forced water from the caves onto the streets of Sharon Springs, flooding most of thetown roads and putting as much as 6 feet of water in the basements of as many as 100 homes. Portions of State Routes 20 and 10were flooded as well. Many local businesses were disrupted and up to 14 people were left homeless. A state of emergency wasdeclared during the week of April 8-15.

Some relief to the long-term drought occurred at mid-month, but for the most part, the rainfall deficit for the three-year periodactually grew larger by the end of April. Mandatory water restrictions continued at a few mountain locations, with voluntary waterrestrictions urged at many others. Numerous wells went dry during April.

Wet snow fell through the morning, resulting in accumulations ranging from 1 to 3 inches. The southernmost sections of this areawere only affected at the highest elevations.

The headwaters of the Red River received the most snow over the course of the winter. Snow water equivalents of 4 to 5 inches weremeasured from the snowpack over this area. As the snowmelt progressed through early April, several heavy rain events occurred.The first, on the 7th of April, brought widespread rainfall amounts of 1 to 2 inches to the southern Red River basin. This rain fell ontop of the remaining snowpack, which resulted in faster rises on the Red and Wild Rice Rivers. Both the Bois de Sioux and OttertailRivers crested at the same time in Wahpeton, something that hadn't happened in recent memory. This brought the first crest on theRed River at Wahpeton, 16.96 feet on the 9th. A second heavy rain event occurred on the 11th and 12th of April, with manylocations south of Wahpeton-Breckenridge reporting 1 to 1.50 inches of rain. This led to a second crest at Wahpeton on the 13th of16.21 feet. As the Red continued to fall after this second crest, a winter storm event occurred on the 22nd and 23rd. This stormbrought over a foot of snow to some locations in Richland county. As this snow rapidly melted over the next couple of days, itbrought a third crest on the Red River at Wahpeton on the 26th at 13.88 feet. The 16.96 foot crest was the 5th highest crest onrecord. 3 of the top 5 Wahpeton crests have occurred since 1996. As the snowmelt progressed across southern Richland county,overland flooding caused major problems between the Wild Rice and Red Rivers. The town of Great Bend had numerous farmsteadssurrounded by water. Many roads were washed out from the overland flooding and many roads and bridges were closed. The WildRice River at Abercrombie also crested 3 times, with the first crest also being the highest at 25.22 feet. This was the third highestcrest on record.

A heavy rain event on April 7th brought a widespread swath of 1 to 2 inchesof rain to the Red River basin. This rain event, along with the snowmelt runoff, contributed to the crest of 36.69 feet in Fargo on the14th of April. This was the 4th highest crest ever at Fargo. Another rain event on the 11th and 12th, and a winter storm that brought7.9 inches of snow on the 22nd and 23rd, helped keep the Maple, Rush, Sheyenne, and Red Rivers high for nearly the whole month.The flooding caused heavy damage to the roads, streets, and bridges in Cass county. The West Fargo Diversion channel was openedon April 4th, reaching a crest of 22.13 feet on the 11th. This was the second highest crest in the diversion's short life span. The areanorth of West Fargo to Harwood turned into a big lake once again, surrounding many homes with water. One link to Moorhead wasclosed due to high water, which was the 1st Avenue North bridge. One section of temporary dike failed along the Red River inFargo, flooding the El Zagal Golf Course. Another temporary dike was built along 64th Avenue South in Fargo, to prevent theoverland flooding that caused major havoc to Fargo during the record flood of 1997.

TheEnglish Coulee backup up from the high Red River level, forcing some sandbagging of homes in north Grand Forks. The Burkeaddition was also cut off by the high river, leaving 26 homes without road access. Another rain event further south on the 11th and12th, and a winter storm on the 22nd and 23rd helped hold up the Red River level through most of the month.

April 2001 was unseasonably dry month for Eastern Pennsylvania, especially during the second half of the month when very little rainfell. On a county weighted average, April monthly precipitation totals ranged from 1.5 inches in Philadelphia County to 2.8 inches inBerks County. This was about 50 percent of normal and most of the precipitation fell prior to April 14th. At the PhiladelphiaInternational Airport, the monthly precipitation total of 1.47 inches was the ninth driest April on record. No measurable precipitationfell at Philadelphia International Airport from April 25th through May 19th, a string of 25 consecutive days and the longest streakwithout measurable precipitation during the spring months (March, April, May) on record. In addition to raising the fire danger, theunseasonably dry weather, if it persists, will threaten the growing season.

A closed upper level low over the central Rockies was deepening as a surface low developed over southeastern Colorado. Strong700mb warm air advection over-ran cold air at the surface. The atmosphere over northeastern Wyoming and western South Dakotawas saturated, with additional moisture being advected in. 300mb Jet streaks were producing strong divergence aloft and robust500mb omega set up along the deformation zone. These features combined to produce heavy snowfall over much of southwestern andsouthern South Dakota for several hours. The precipitation began as rain in the warm over-running air. This rain quickly changed tosnow and accumulated rapidly. The area of snowfall with this system extended in a 300 mile wide path from northern Colorado toeastern South Dakota. The path was defined by sharp edges as seen in satellite images. The heaviest snow fell over the easternfoothills and eastern Black Hills where local upslope effects dramatically affected snowfall amounts. The area of maximum snowfallextended from southern Meade County westward to the central and southern Black Hills where 12 to 22 inches covered the ground.Rapid City, in the eastern foothills, recorded a daily snowfall record of 20 inches. Elsewhere across the plains of southwestern andsouth-central South Dakota 6 to 12 inches of snow were reported.

A strong low pressure system dragged an occluded front through Wisconsin as the low moved northeast across Minnesota. Highwinds behind the front downed numerous trees, tree limbs and power poles across central, east central and northeast Wisconsin. Thewind removed part of the roof of a building in Rosholt (Portage co.) and knocked over a billboard in Outagamie county. The windand accompanying warm and dry air contributed to the development of grass fires in the Coloma and Red Granite (Waushara co.)areas.

High winds drove slabs of ice from Lake Winnebago onto the shore. A dead end street in Oshkosh (Winnebago co.) at LakeWinnebago was piled with a 20-foot to 30-foot high mountain of ice that threatened at least one home.

A gust of 55 knots (63 mph) wasrecorded at the NWS Forecast Office near Sullivan (Jefferson Co.).

Synoptically, a gravity wave with associated widespread rain showers moved northeast out of Illinois and across southeasternWisconsin. Some of the strongest gusts occurred when rain showers were observed. The convection most likely contributed to themixing and transfer of high-momentum air down to the surface.

Heavy rains, combined with snow melt runoff, caused the Mississippi River to reach near record levels. In fact, at most locations thewater reached levels second only to the all-time flood of record, which occurred in April 1965. The Mississippi River at La Crosse(La Crosse County) crested at 16.4 feet on April 18, which was the third all-time highest flood on record. Hardest hit was the Prairiedu Chien area (Crawford County) and points southward, where flood waters did considerable damage to businesses and homes.Overall damage due to the high water was estimated around 6 million dollars.

Heavy snow fall during winter remained on the ground through the end of March and then rapidly melted, resulting in river stagesclose to record levels along Wisconsin's western border. Water began to gush through drainage ditches, streams and into themainstem rivers during midday April 1. Two to four inches of rain April 7-9 prolonged the high water and also added about one footto the crest during mid-April. Another two to three inches of rain April 22-23 caused a second crest in late April. Both the St. Croixand Mississippi Rivers remained well above flood stage into May (see May 2001 Storm Data). The crest at Stillwater MN on the St.Croix River was the second highest crest, only 1.8 feet lower than in 1965. The crest at Hastings MN and Red Wing MN on theMississippi River was the third highest level, lower only than during the floods of 1965 and 1969.

A few homes and businesses in Durand (Pepin County) and Prescott (Pierce County) had water in basements, and one office buildingin Hudson (St. Croix County) was engulfed by the St. Croix River. Numerous county roads and bridges were under water, and the

The Saffir-Simpson Scale

Category One Hurricane:

Winds 74-95 mph (64-82 kt or 119-153 kph). Storm surge generally 4-5 ft above normal. No real damage tobuilding structures. Damage primarily to unanchored mobile homes, shrubbery, and trees. Some damage topoorly constructed signs. Also, some coastal road flooding and minor pier damage.

Category Two Hurricane:

Winds 96-110 mph (83-95 kt or 154-177 kph). Storm surge generally 6-8 feet above normal. Some roofingmaterial, door, and window damage of buildings. Considerable damage to shrubbery and trees with some treesblown down. Considerable damage to mobile homes, poorly constructed signs, and piers. Coastal and low-lying escape routes flood 2-4 hours before arrival of the hurricane center. Small craft in unprotectedanchorages break moorings.

Category Three Hurricane:

Winds 111-130 mph (96-113 kt or 178-209 kph). Storm surge generally 9-12 ft above normal. Some structuraldamage to small residences and utility buildings with a minor amount of curtainwall failures. Damage toshrubbery and trees with foliage blown off trees and large tress blown down. Mobile homes and poorlyconstructed signs are destroyed. Low-lying escape routes are cut by rising water 3-5 hours before arrival ofthe hurricane center. Flooding near the coast destroys smaller structures with larger structures damaged bybattering of floating debris. Terrain continuously lower than 5 ft above mean sea level may be flooded inland8 miles (13 km) or more. Evacuation of low-lying residences with several blocks of the shoreline may berequired.

Category Four Hurricane:

Winds 131-155 mph (114-135 kt or 210-249 kph). Storm surge generally 13-18 ft above normal. Moreextensive curtainwall failures with some complete roof structure failures on small residences. Shrubs, trees,and all signs are blown down. Complete destruction of mobile homes. Extensive damage to doors andwindows. Low-lying escape routes may be cut by rising water 3-5 hours before arrival of the hurricane center.Major damage to lower floors of structures near the shore. Terrain lower than 10 ft above sea level may beflooded requiring massive evacuation of residential areas as far inland as 6 miles (10 km).

Category Five Hurricane:

Winds greater than 155 mph (135 kt or 249 kph). Storm surge generally greater than 18 ft above normal.Complete roof failure on many residences and industrial buildings. Some complete building failures withsmall utility buildings blown over or away. All shrubs, trees, and signs blown down. Complete destructon ofmobile homes. Severe and extensive window and door damage. Low-lying escape routes are cut by risingwater 3-5 hours before arrival of the hurricane center. Major damage to lower floors of all structures locatedless than 15 ft above sea level and within 500 yards of the shoreline. Massive evacuation of residential areason low ground within 5-10 miles (8-16 km) of the shoreline may be required.
