The official Atlantic hurricane season runs from June through November, but occasionally storms form outside those months. Seasonal hurricane forecasting from Colorado State University is available here.
According to the National Oceanic and Atmospheric Administration, a tropical cyclone is a rotating low-pressure weather system that has organized thunderstorms but no fronts, Hurricanes are tropical cyclones that have sustained winds of 74 mph. At this point a hurricane reaches Category 1 on the Saffir-Simpson Hurricane Wind Scale, which ranges from 1 to 5, based on the hurricane’s intensity at the time of landfall at the location experiencing the strongest winds. The scale provides examples of the type of damage and impacts in the United States associated with winds of the indicated intensity. It does not address the potential for other hurricane-related phenomena such as storm surge, rainfall-induced floods and tornadoes.
