What the Tornado EF Scale Means
The Enhanced Fujita Scale uses 28 damage indicators to rate tornadoes from EF0 minor to EF5 incredible damage, improving accuracy for modern structures, the NWS said.
- The Enhanced Fujita Scale serves as the primary system used by the National Weather Service to estimate tornado strength, ranking from EF0 to EF5 based on damage. Meteorologists analyze damage to estimate wind speeds, with higher numbers indicating more destructive storms.
- To measure wind strength, meteorologists analyze three-second gusts and survey multiple structures because measuring ground-level wind is difficult.
- Damage ranges from minor to incredible, categorized by specific wind speeds; EF0 causes minor damage while EF5 results in incredible destruction.
- Ultimately, these ratings help improve future forecasts, public safety reports, and building codes, helping the national weather service better prepare the public for future storms.
- The Enhanced Fujita Scale provides more accurate wind impact data for newer structures, replacing the original Fujita Scale developed by Ted Fujita.
