PACIFIC WINTER STORM CAUSES FLOODING AND LANDSLIDES IN
OREGON AND WASHINGTON
A LOCAL CHALLENGE BECAUSE OF MOUNT HOOD, BUT NOT A DISASTER
JANUARY 16-18, 2011

LOCATION MAP (NOTE: PORTLAND AT LEFT CENTER)
A Pacific storm that swept through the Northwest USA brought heavy rain to Oregon and Washington, causing multiple landslides and
shutting down important roads that facilitate travel cross the region..
MOUNT HOOD
MOUNT HOOD: PART OF THE SITUATION
Mount Hood, a stratovolcano in northern Oregon that is located about 50 miles (80 km) east-southeast of Portland, was snow bound..
6 to 10 inches (15 - 25 cm) of rain that fell in 24 hours in the Sandy River drainage basin accelerated
the melting and subsequent runoff of 2 inches (5 cm) of snow on the
flanks of Mount Hood and triggered landslides.
.
The runoff from heavy rain and snowmelt on Mount Hood
combined to swell a river that washed out a road near Mount Hood, forcing residents to flee their neighborhoods on foot.

IMPACT ON RESIDENTS
Residents that could not or did not evacuate were temporarily isolated as a result of the heavy rains, rising waters, landslides, and loss of use of the roads.
