Hurricane Formation Powered largely by warm water Hurricanes are most common late summer to fall – ‘hurricane season’ –Varies by region Weaken over land –Usually weaken as they approach coastline also Form near but not over equator, given proper conditions (next slide)

Ingredients for Hurricane Formation Warm water – at least 80oF Relatively cool air at altitude Relatively moist air at moderate altitude (3 miles up) At least 300 miles from the equator Little wind shear between surface and upper air (6 miles up) Divergence aloft A trigger – e.g., big thunderstorms

Hurricane Hazards Storm Surge –On average, the biggest threat to life and property Winds Flooding from extreme precipitation –Can cause major problems far inland

Galveston Hurricane, 1900 > 10,000 fatalities, worst natural disaster in U.S. history
