Hurricanes are a group of storm clouds that create a very dangerous storm. If you see a hurricane from space, you will see a giant swirling cloud. Hurricanes can bring heavy rain, wind, and sometimes minor tornadoes. Hurricanes are formed when storm clouds form over warm water. As the storm clouds move, the warm water fuels the storm. The strong winds of the hurricane create the swirling motion. The storm is not a hurricane yet! It is a tropical depression. It still needs more strength to be a hurricane. As it moves over the ocean, it increases in strength. The middle of the hurricane is called the eye and is the calmest part. When the hurricane makes landfall, it can move for miles, but it loses energy as it travels over land. That is what hurricanes are!
