Saffir-Simpson Hurricane Intensity Scale

The Saffir-Simpson Hurricane Intensity Scale is used to categorize hurricane strength and potential damage. Public broadcasts generally include a hurricane’s category. This table shows the parameters (wind speed and storm surge), criteria, and expected damage of each category of hurricane.
