Hurricane categories, explained.
The Saffir–Simpson Hurricane Wind Scale rates hurricanes by their maximum sustained wind speed. It does not measure flooding, rainfall, storm surge or the size of the storm.
| Category | Sustained winds |
|---|---|
| 1 | 74–95 mph |
| 2 | 96–110 mph |
| 3 | 111–129 mph |
| 4 | 130–156 mph |
| 5 | 157 mph or higher |
What is a major hurricane?
Categories 3, 4 and 5 are called major hurricanes. Every hurricane can cause dangerous conditions. A weaker storm can still produce destructive flooding, especially if it moves slowly or affects a vulnerable coastline.
Category is not your local forecast
The maximum wind speed occurs in a part of the storm, not everywhere it affects. Your exposure depends on location, storm size, terrain and other factors. Follow the specific local warnings and evacuation instructions for your area.
