Hurricanes have winds of at least 74 miles per hour, according to NASA. Hurricanes aren't the only storms that produce winds this fast, so these storms are categorized by their combination of fast-moving, swirling winds and rain.
Meteorologists classify hurricanes based on their wind speed. A hurricane with a 74 mph wind is a Category 1 hurricane. Category 2 winds are at least 96 mph. Category 3 winds are at least 111 mph. A Category 4 hurricane has wind speeds of at least 131 mph, and those of a Category 5 are at least 155 mph. The Gulf Coast and the coast of Florida have experienced numerous hurricanes that were traveling in excess of 100 mph when they struck land.
