1 The History, Structure, Development, and Destruction Source: http://www.dc.peachnet.edu/~pgore/students/w97/matheson/hpage.htm

2  Violent cyclonic storm that develops in the tropical region  Wind speeds are > 74 mph Source: http://earthobservatory.nasa.gov/ Newsroom/NewImages/images.php3?img_id=680

3 In which direction does a hurricane rotate? COUNTERCLOCKWISE Is the barometric pressure inside the hurricane high or low? LOW

4 June 1 st through November 31st

5  Provides weather information, such as data from satellites  Responsible for issuing watches and warnings to the media and general public

6  What is the difference between a Hurricane Watch and a Hurricane Warning? Watch – Tropical storm poses a threat to coastal areas with 36 hours Warning - Tropical storm conditions are expected in a coastal area within 24 hours

7  Warm ocean temperatures (>80˚ F) up to 60m deep  Little to no wind shear  Low pressure system at least 5˚ North or South of Equator  Rotation caused by winds Source: http://lwf.ncdc.noaa. gov/oa/reports/fran/fran.html

11 TTropical Disturbance Group of thunderstorms in the tropics that are present for at least 24 hours TTropical Wave lack of circulation, winds <25 mph and every direction TTropical Depression closed circulation but disorganized, winds at least 25 mph

12 Tropical Storm Shower and thunderstorm moves over closed circulation, winds greater than 39 mph Hurricane Eye is developed, winds > 74 mph

16  Winds  Flooding  Storm Surge

17  Large wall or dome of water that rushes into the coastline as a result of a hurricane making landfall  To the right are the areas affected by high storm surges Souce: http://www.wkrg.com/hurricanecenter/surge/SE.jpg

18  Strong vertical winds  Cold water  Movement over land  Friction  Lack of moisture

19 1. Hurricane Andrew – 1992 2. Hurricane Hugo – 1989 3. Hurricane Fran – 1996 4. Hurricane Opal – 1995 5. Hurricane Frederic - 1979

20 DDamage is a result of development TThere are more developed areas and possessions than in the past Source: http://www.nhc.noaa.gov/1992andrew.html

21 1. Galveston – 1900 2. Southeast Florida – 1928 3. Florida Keys – 1919 4. New England – 1938 5. Florida Keys – 1935

22  Lack of instrumentation to predict and track storms  People were not warned of the incoming danger Source: http://www.1900storm.com/photographs/photo10.html Results of the Galveston Hurricane

24  Damage to your house from wind?  Damage from flooding?  Destroyed vacation house?  Damage to family members’ homes?
