Hurricane
A hurricane is a severe cyclone originating over tropical ocean waters and having one-minute sustained surface winds 64 knots (74 miles per hour) or higher (33 meters per second).

They rotate counter-clockwise around an  eye.

West of the international date line, in the western Pacific, such storms are known as typhoons.

In the U.S., the official hurricane season is from June 1 to November 30, but hurricanes can happen at any time of the year.

Hurricanes are named by the National Weather Service.

This is the Saffir-Simpson scale.

The Saffir-Simpson Hurricane Scale is a 1 - 5 rating based on a hurricane's intensity. The scale is used to give an estimate of the potential property damage and flooding expected along the coast from a hurricane landfall. Wind speed is the determining factor in the scale.
