THE SAFFIR-SIMPSON SCALE This hurricane wind scale is used to categorize hurricanes on a 1 to 5 rating based solely on a hurricane's maximum wind speed. The scale estimates potential property damage. The higher the number, the stronger the winds, the greater the damage. It does not take into account other potential storm hazards such as rainfall amounts and flooding and tornadoes. #hurricaneseason #beryl #texas #saffirsimpson | Jeannette Calle WOAI
