The Saffir-Simpson scale measures the intensity of a hurricane. Wind speed is measured on a scale of 1-5 to give an estimate of potential property damage and flooding along the coast. The Categories are as follows: Category One Hurricane: Winds 74-95 mph.
The original Saffir-Simpson Hurricane Damage-Potential Scale is a hurricane force scale using the numbers 1-5 to rate a hurricane's intensity. The scale was developed by engineer Herbert Saffir and pioneer hurricane expert Dr Robert Simpson in 1971. The scale is assigned to a hurricane based on its peak wind speed. The scale is used to give an estimate of the potential property damage and flooding expected along the coast from a hurricane landfall.
