Question: Why do Hurricanes Occur in the Caribbean?
Without getting too technical, hurricanes form around areas of extremely low pressure over warm ocean waters (like those in the Caribbean and South Atlantic) in the summer and fall. Most Caribbean hurricanes actually begin life as tropical waves or depressions over the eastern Atlantic (sometimes off the west coast of Africa) and follow the trade winds west, gathering strength and often reaching their peak of power in the Caribbean basin. Occasionally storms also form locally over the Caribbean itself.
