In addition Hurricanes rotate in a counter-clockwise direction around the eye. The rotating storm clouds create the "eye wall," which is the most destructive part of the storm.
Hurricanes form over warm ocean waters near the equator. The warm, moist air above the ocean surface rises, causing air from surrounding areas to be “sucked” in. This “new” air then becomes warm and moist, and rises, too, beginning a continuous cycle that forms clouds. The clouds then rotate with the spin of the Earth. If there is enough warm water to feed the storm, a hurricane forms!
