Here is a look at the 2015 Atlantic hurricane season.

Facts

The 2015 Atlantic hurricane season runs from June 1 to November 30. The areas covered include the North Atlantic Ocean, Gulf of Mexico and Caribbean Sea.

The National Weather Service defines a hurricane as “an intense tropical weather system with well-defined circulation and sustained winds of 74 mph (64 knots) or higher.”

Hurricanes are rated according to intensity on the Saffir-Simpson Hurricane Wind Scale.

The 1-5 scale estimates potential property damage.

A Category 3 or higher is considered a major hurricane.

The National Hurricane Center advises preparedness:

A hurricane watch indicates the possibility that a region could experience hurricane conditions within 48 hours.

A hurricane warning indicates that sustained winds of at least 74 mph are expected within 36 hours.

Predictions
April 9, 2015 - The Tropical Meteorology Project from Colorado State University predicts that the “2015 Atlantic basin hurricane season will be one of the least active seasons since the middle of the 20th century.” They predict seven named storms and three hurricanes.

May 27, 2015 - The National Oceanic and Atmospheric Administration forecasts a below-normal hurricane season, predicting that there is a 70 percent chance of having six to 11 named storms, of which three to six could develop into hurricanes, including zero to two major hurricanes (categories 3-5).
