Hurricanes Facts
A hurricane, also known as a tropical cyclone, is a storm system that rotates rapidly. It has a low-pressure center with thunderstorms in a spiral formation that produce high winds and a lot of heavy rain. Tropical cyclones, depending on where they are located and how strong they are, can be called hurricanes, typhoons, tropical storms, tropical depressions, and cyclonic storms. Hurricanes form over bodies of warm water, gaining their energy from the water that evaporates from the surface of the ocean. This evaporated water then forms clouds and ultimately rain. Once a cyclone reaches 75 mile per hour winds, it is classified as a hurricane.
