Hurricanes can be up to 600 miles wide and have winds of 75 to 200 mph.

Around the U.S., only women's names were used until 1979. Then it was decided that they should alternate a list that included men's names too.
There's 6 different name lists that alternate each year. If a hurricane does significant damage, its name is retired and replaced with another.
