What is the EF Scale?

The Enhanced Fujita Scale (EF Scale) is used to give a tornado a rating based on estimated wind speeds and related damage. The EF scale is a set of wind estimates, not measurements, based on damage.

The National Weather Service is the only federal agency with the authority to provide official tornado EF Scale ratings. The aim is to give a tornado an EF Scale category based on the highest wind speed that occurred within the damage path.

  • EF-0: 65-85 mph
  • EF-1: 86-110 mph
  • EF-2: 111-135 mph
  • EF-3: 136-165 mph
  • EF-4: 166-200 mph
  • EF-5: Over 200 mph
