Hurricanes are cyclonic circulations with sustained winds of 74 mph or greater. These destructive storms can produce heavy rains, high winds and flooding when they make landfall. In the Northern Hemisphere, these storms can form anywhere in the Atlantic Ocean, Caribbean Sea, or the Gulf of Mexico. While hurricanes typically form from June through November, they can form at anytime of the year.
Hurricanes are a major threat to the Houston–Galveston region. Depending on the severity of the hurricane, it may become necessary to evacuation portions of the Houston–Galveston region. The Houston–Galveston Area Council (H–GAC) works closely with the State and local jurisdictions to aid in the planning of regional evacuations. One example of these efforts is the Together against the Weather website that provides information to persons with functional needs and their caregivers.
