Saffir-Simpson Scale: This scale classifies hurricanes based on their intensity, and is used to predict how damaging the hurricane will be to property. Saffir-Simpson classifies hurricanes from a scale of 1 (minimal) to 5 (catastrophic.)

This scale was developed in the early 1970s by Herbert Saffir, a consulting engineer in Coral Gables, Florida, and Dr. Robert Simpson, then Director of the National Hurricane Center. The scale is based primarily on wind speeds and includes estimates of barometric pressure and storm surge associated with each of the five categories.
