General Emergency Information

A hurricane is a severe tropical storm that forms in the southern Atlantic Ocean, Caribbean Sea, Gulf of Mexico or eastern Pacific Ocean. Hurricanes rotate in a counterclockwise direction around an "eye." They have winds at least 75 mph. When they come onto land, they can bring heavy rain, strong winds and floods, and can damage buildings, trees and cars. They also produce heavy waves called storm surge. Storm surges are very dangerous and a major reason why people must stay away from the ocean during a hurricane warning.

Classification: Hurricanes are classified into five categories, based on wind speed and potential to cause damage:

Category One – Winds 74-95 mph
Category Two – Winds 96-110 mph
Category Three – Winds 111-130 mph
Category Four – Winds 131-155 mph
Category Five – Winds greater than 155 mph

In coastal or near-coastal areas, a hurricane warning can remain in effect when dangerously high water, or a combination of dangerously high water and exceptionally high waves, continues, even though the winds may have subsided below hurricane intensity.
