Named for Huracan, the Carib god of evil, the hurricane is an amazing yet destructive natural phenomenon that occurs about 40 to 50 times worldwide each year. Hurricane season takes place in the Atlantic, Caribbean, Gulf of Mexico, and Central Pacific from June 1 to November 30 while in the Eastern Pacific the season is from May 15 to November 30.

Due to the Coriolis effect, the regions between 5° and 20° north and south of the equator are the belts where hurricanes can form (there is not enough rotary motion between 5° north and south. The term cyclone is used in the Bay of Bengal and Arabian Sea and the term typhoon is used in the Pacific Ocean north of the equator and west of the International Dateline.

The birth of a hurricane starts as a low pressure zone and builds into a tropical wave of low pressure.

In addition to a disturbance in the tropical ocean water, the storms that become hurricanes also require warm ocean waters (above 80°F or 27°C down to 150 feet or 50 meters below sea level) and light upper level winds.

A tropical wave grows in intensity and then may grow to become an organized area of showers and thunderstorms known as a tropical disturbance. This disturbance becomes an organized area of tropical low pressure that is called a tropical depression based on cyclonic winds (counter-clockwise in the Northern Hemisphere and clockwise in the Southern Hemisphere). A tropical depression's wind speed must be at or below 38 miles per hour (mph) or 62 km/hr when averaged out over one minute. These winds are measured at 33 feet (10 meters) above the surface.
