What is a hurricane?A hurricane is a very destructive and dangerous storm. It forms in stages. The hurricanes are filled with rain, strong winds, lightning, thunder, hail and tornadoes. In these storms, when the winds range from 35 to 54 miles an hour, it is called a tropical depression. When the winds are from 55 to 74 miles an hour then it is called a tropical storm. When it reaches 75 miles an hour, it is called a hurricane.
Hurricanes rotate counterclockwise in the northern hemisphere and clockwise in the southern hemisphere.
What is eye of a hurricane?
While some hurricanes, are small, others can be quite large. Hurricanes are mighty storms.
In the center of a hurricane is an eye. Ironically, the eye is actually a calm area in a hurricane.
How do hurricanes travel?Hurricanes have “paths” in which they travel and move at different speeds over water and land. Once they hit land, they do slow down and weaken. Warm water “feeds” the hurricane and helps them grow larger and stronger.
When hurricanes make “landfall” they have entered land a certain area. Due to the fact that they are huge storms, the areas surrounding landfall are also affected.
What’s in a name?Hurricanes are named now, In the West Indies for hundreds of years they were often named after the particular saint’s day on which the hurricane occurred.
During World War II, they practiced using women’s names for the storms. In 1951 the United States adopted a plan to name storms by a phonetic alphabet (Able, Baker, Charlie), but found it confusing.
From 1953 until 1978, the nation’s weather services used female names.
In 1979, both male and female names were included in lists for the Atlantic and Gulf of Mexico.

How do they measure hurricanes?
What does evacuate mean?
• Evacuate: You and your family may be asked to leave your home. You can return after your town or state leaders say you can return.
What does flooding mean?
• Floods: Flooding occurs when water rises. More people are killed by floods during a hurricane than by any other hazard. Tidal surges push water in hurricanes and can cause flooding.
What is a storm surge?• Storm surge: Storm surge is a
massive dome of water, that sweeps across the coast near the area where the eye of the hurricane comes makes landfall. The stronger the hurricane the higher the storm surge. For those living along the coast, storm surge is one of the most dangerous parts of a hurricane. Here are examples of a storm surge flooding a town.
What is a hurricane watch & warning?
• Hurricane Watch: A hurricane is possible within 36 hours. Listen closely to the radio and television for more information. It is very important for your parents to listen for the hurricane updates.
• Hurricane Warning: A hurricane is expected within 24 hours. You may be told to evacuate. You and your family should begin preparations to evacuate.
What can you do?
• Listen to the radio: Get radio and extra batteries for it, and be sure to listen to it during a hurricane or any emergency.
• The radio will tell you when you need to take shelter.
What can you do?
• Prepare your house for the storm!• Help your parents get the
house ready by picking up loose items in the yard, covering windows plywood, removing roof antennas and turning off utilities.
What can you do?• Disaster supply kit: Make
sure your family has a disaster supply kit assembled and ready to use.
• Disaster meeting place: Ask your family to decide on a meeting place in case you get separated during a disaster. Choose an out-of-town relative or friend who you can check in with to say you're OK.
What can you do?• Pets: If you have pets, you
need to find a place for them to stay if you have to evacuate your home.• Make sure this safe place is
outside the evacuated area. If your family plans to stay in a public shelter, you may have to keep your pets somewhere else.
• You could also take shelter in a hotel, but make sure they accept pets before you evacuate
Keep Track of the Hurricane
• If you know how, try to keep track of the hurricane.
• You can see it on the internet (if you are away from the storm) or listen to a radio and download a hurricane tracking chart.
• When a hurricane forms, you can follow its course by listening to the news on the radio and you can plot it on the chart.
The 1900 stormThe 1900 Galveston
storm started out on the West coast of Africa as a tropical storm. Its strength increased rapidly and went all the way to the Gulf of Mexico. It passed by the Caribbean before and caused a lot of damage in Cuba.
The hurricane hit….
• On September 8th and left to the Atlantic ocean on September 15, 1900.
Deaths and destruction
• As many as 6,000 people died, and more than two-thirds of the burgeoning city's buildings were destroyed.
8 September 1900
Has technology changed hurricane situations?
Think about this. How do you think technology has changed Hurricane awareness and safety? The map on the left is a map from Hurricane Hilda in 1964. The map on the right is a map of Hurricane Rita in 2005. If the technology now available had existed for the 1900 Galveston Hurricane, could the outcome have been different? How? Why? Explain your answer to the class or write a paragraph about it.
