A Category 4 hurricane is characterized by its incredibly powerful sustained winds, which range from 130 to 156 miles per hour (mph). These winds are what define its intensity on the Saffir-Simpson Hurricane Wind Scale.
Understanding Category 4 Hurricane Winds
The speed of a Category 4 hurricane refers to the sustained wind speeds generated within the storm system. This scale classifies hurricanes based on their maximum sustained surface winds, providing an estimate of potential property damage and the significant hazards these storms pose.
Here's a breakdown of the Saffir-Simpson Hurricane Wind Scale for major hurricanes:
| Category | Sustained Wind Speed (mph) | Sustained Wind Speed (km/h) |
|---|---|---|
| 3 (Major) | 111-129 | 178-208 |
| 4 (Major) | 130-156 | 209-251 |
| 5 (Major) | 157 or higher | 252 or higher |
Impact of Category 4 Winds
Hurricanes reaching Category 4 strength are considered major hurricanes due to their extreme destructive potential. Winds in this range can cause:
- Catastrophic damage to well-built homes, with severe damage to roofs and exterior walls.
- Most trees to be snapped or uprooted, isolating residential areas.
- Extensive power outages that could last for weeks or even months.
- Large areas to be uninhabitable for extended periods.
These powerful winds are the defining characteristic of a Category 4 hurricane, indicating the immense force of the air moving within the storm.
