The Fujita Scale has been replaced with the newer Enhanced Fujita (EF) Scale. You can learn about the EF Scale and its relationship to the F-Scale at the National Weather Service website. One advantage of the older Fujita Scale, however, is that it sometimes makes it easier for the general public to understand the rough correlation between tornado wind speed and resulting damage. As you look at these windspeeds and the types of damage they can cause, it’s important to remember that fewer than 2% of all tornadoes fall in the F-4 or F-5 category.
|Rating|| Wind Speed
|F-0||40-72||Light: Some chimney damage, broken tree branches, damaged sign boards.|
|F-1||73-112||Moderate: Mobile homes moved or overturned, roofing stripped off houses, moving autos pushed off roads.|
|F-2||113-157||Considerable: Mobile homes demolished; roofs torn from frame houses; large trees snapped or uprooted.|
|F-3||158-206||Severe: Roofs and most outer walls torn off even well-built houses; trains overturned.|
|F-4||207-260||Devastating: All houses leveled and some are blown some distance from their foundations; autos thrown through the air.|
|F-5||261-318||Incredible: Houses picked up and carried considerable distance in pieces, automobiles fly through the air farther than 100 yards; pavement removed from highways.|
