The Atlantic hurricane season is officially from June 1 to November 30. Over 97% of tropical activity occurs in these six months, but hurricanes have occurred in every month of the year. According to the National Oceanic and Atmospheric Association (NOAA), the most common month for hurricanes is September. Bottom line: We should be prepared year-round.
Tropical Depression: An organized system of clouds and thunderstorms with a defined surface circulation and maximum sustained winds of 38 mph (33kt) or less.
Tropical Storm: An organized system of strong thunderstorms with a defined surface circulation and maximum sustained winds of 39 - 73 mph (34 - 63 kt).
Hurricane: An intense tropical weather system of strong thunderstorms with a well-defined surface circulation and maximum sustained winds of 74 mph (64 kt) or higher. In other parts of the world, the word hurricane is synonymous with typhoon and cyclone.
Monitor weather reports frequently and heed the advice of local officials during hurricane season. Tropical systems can speed up, change direction and intensify without warning.
