Saffir-Simpson Hurricane Wind Scale

We just learned about Tropical Storms.

Another type of tropical cyclone is a Hurricane.

For a tropical cyclone to be called a hurricane, it has to have winds over 74 miles per hour for over a minute.

Hurricanes are put into categories of 1 to 5 based on how strong they are.
There is a scale called the Saffir-Simpson Hurricane Wind Scale, which scientists use to tell which category number the hurricane is, based on how strong the wind is.
