Here is a look at the 2021 Atlantic hurricane season.
Facts
The 2021 Atlantic hurricane season runs from June 1 to November 30. The areas covered include the Atlantic Ocean, Gulf of Mexico and the Caribbean Sea.
The National Weather Service defines a hurricane as a “tropical cyclone with maximum sustained winds of 74 mph (64 knots) or higher.”
Hurricanes are rated according to intensity of sustained winds 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.
