NOAA classifies hurricanes 1–5 by sustained wind speed. The category describes wind intensity only — storm surge and rainfall flooding are reported and assessed separately.
| Category | Measurement | Typical property impact |
|---|---|---|
| Category 1 | 74–95 mph | Some damage: roof, siding, and large tree limbs |
| Category 2 | 96–110 mph | Extensive damage: roof and siding, trees snapped or uprooted |
| Category 3 | 111–129 mph | Devastating damage: major roof and wall damage |
| Category 4 | 130–156 mph | Catastrophic damage: severe structural damage |
| Category 5 | 157 mph+ | Catastrophic damage: total roof failure and wall collapse possible |
