The scale used to measure hurricanes is the Saffir-Simpson Hurricane Wind Scale. This scale categorizes hurricanes into five categories based on sustained wind speeds and potential damage. Category 1 represents a minimal hurricane, while Category 5 denotes a catastrophic hurricane with wind speeds exceeding 157 mph. The scale helps assess the expected impact of a hurricane on infrastructure and the environment, aiding in preparedness and response efforts. It's important to note that while the wind speed is a critical factor, other components such as storm surge and rainfall also play significant roles in determining a hurricane's overall impact.
