The Saffir-Simpson Hurricane Wind Scale categorizes hurricanes based on their sustained wind speeds and estimates the potential damage they can cause. A hurricane rated as a Category 4 means that it has sustained wind speeds of 130 to 156 miles per hour (209 to 251 kilometers per hour).
Category 4 hurricanes can cause devastating damage, including:
- Severe damage to well-built homes, with a high likelihood of loss of roofs and exterior walls.
- The majority of trees will be snapped or uprooted, blocking roads and causing power outages for extended periods (possibly weeks to months).
- Power outages are expected to last several days to weeks, with the possibility that entire communities could be without electricity.
- Flooding can occur in low-lying areas, causing significant disruptions.
Given the potential for extensive damage and danger, preparations and evacuations are typically recommended for areas in the projected path of a Category 4 hurricane.
