Hurricanes are most frequently associated with the Atlantic Ocean and the Gulf of Mexico, but can also occur in the Pacific. They are called cyclones in the Indian Ocean and typhoons in the western Pacific Ocean. An average size of the storm is about 340 miles in diameter.

Hurricanes are the most powerful of all weather systems.
They act like giant wheels of clouds, spinning over the ocean until they reach a cooler area like land and then die down. There are three parts of a hurricane - eye, eye wall and down draft . In the eye,the center of hurricane, the weather is usually calm with light winds. The winds are most violent just outside the eye, on the eye wall . As the eye passes overhead, the rain stops for a short time and starts again.
