Understanding Hurricanes

What is a Hurricane?
A hurricane, also called a tropical cyclone, is a rotating storm system with organized thunderstorms and no fronts. It forms over warm ocean waters and is classified by wind speed:

  • Tropical Depression: Winds less than 39 mph

  • Tropical Storm: Winds 39–73 mph

  • Hurricane: Winds 74+ mph

These storms typically form in the Atlantic basin, which includes the Atlantic Ocean, Caribbean Sea, Gulf of Mexico, and parts of the Pacific Ocean.

Hurricane Season:

  • Starts: June 1

  • Ends: November 30

  • Peak: Mid-September

Key Facts:

  • The word “hurricane” comes from the Taino word Huracan, meaning “evil spirit of the winds.”

  • Hurricanes form when warm, moist ocean air rises and begins to rotate.

  • On average, 10 tropical storms form each year in the Atlantic region; about 6 become hurricanes.

  • Coastal areas face the highest risk.

  • Hurricanes have three main parts: the eye, eye wall, and rain bands.

  • They weaken after hitting land due to loss of ocean moisture.
