The 2023 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.

April 13, 2023 – The Colorado State University Tropical Meteorology Project team predicts a “slightly below-normal” Atlantic hurricane season. The team forecasts 13 named storms, including six hurricanes, two of which will be major hurricanes.

August 10, 2023 – NOAA releases its updated forecast, upping the odds for an above average hurricane season from 30% to 60% as ocean temperatures continue to climb above record levels this summer. The agency now predicts 14-21 named storms, including six to 11 hurricanes, of which two to five are forecast to be major. These ranges take into account the named storms that have already formed this season.
