Answers to Hurricane Season FAQs:

Where Do Hurricanes Primarily Occur?

Hurricanes originate in the Atlantic basin, which includes the Atlantic Ocean, Caribbean Sea, and Gulf of Mexico; the eastern North Pacific Ocean; and, less frequently, the central North Pacific Ocean.

Who Provides Hurricane Tracking Data?

NOAA’s National Hurricane Center predicts and tracks these massive storm systems, which occur 12 times a year on average in the Atlantic basin. A six-year rotating list of names, updated and maintained by the World Meteorological Organization, is used to identify these storms.

How Do Hurricanes Develop?

It starts with a rotating low-pressure weather system called a tropical cyclone. Tropical cyclones have organized thunderstorms but no fronts (a boundary separating two air masses of different densities). Tropical depressions are tropical cyclones with maximum sustained surface winds of less than 39 miles per hour (mph). Tropical storms have maximum sustained winds between 39 mph and 73 mph. When a storm’s maximum sustained winds reach 74 mph, it is called a hurricane.

                      What Is the Difference Between A Watch and A Warning?

  Tropical Storm Hurricane Action
Watch An announcement that tropical-storm conditions are possible within the specified area. An announcement that hurricane conditions are possible within the specified area. During a watch, prepare your home and review your plan for evacuation in case a Tropical Storm Warning or Hurricane Warning is issued. Listen closely to instructions from local officials.
Because outside preparedness activities become difficult once winds reach tropical storm force,
watches are issued 48 hours in advance of the anticipated onset of tropical-storm-force winds.
Warning An announcement that tropical-storm conditions are expected within the specified area. An announcement that hurricane conditions are expected within the specified area. During a warning, complete storm preparations and immediately leave the threatened area if directed by local officials.
Because outside preparedness activities become difficult once winds reach tropical storm force,
warnings are issued 36 hours in advance of the anticipated onset of tropical-storm-force winds.
Extreme Winds Extreme sustained winds of a major hurricane (115 mph or greater), usually associated with the eyewall, are expected to begin within an hour. Take immediate shelter in the interior portion of a well-built structure.
