Atlantic hurricanes get their start in Africa. Wind blowing westward off of the coast hits warm ocean water and under the right conditions, storms can form.
The difference in temperature between the air and the sea powers storms.
Inside the storm moisture evaporates and rises, drawing in new air that swirls in behind it.
The rising moisture cools and forms storm clouds, releasing heat. Nudged by Earth’s rotation, the system spins faster and faster.
