What is the EF scale for rating tornadoes?

What is the range on F scale for tornadoes?

The Fujita Scale

F Scale Character Estimated winds
One (F1) Weak 73-112 mph
Two (F2) Strong 113-157 mph
Three (F3) Strong 158-206 mph
Four (F4) Violent 207-260 mph

How bad is a EF0 tornado?

Tornado Classifications: EF0

EF0 tornadoes have wind speeds of 65 to 85 miles per hour. Damage includes loss of roof-covering material (<20%), gutters, and/or awnings; loss of vinyl or metal siding; tree branches broken; and shallow-rooted trees toppled.

What’s the difference between F5 and EF5?

Differences from the Fujita scale

The old scale lists an F5 tornado as wind speeds of 261–318 mph (420–512 km/h), while the new scale lists an EF5 as a tornado with winds above 200 mph (322 km/h), found to be sufficient to cause the damage previously ascribed to the F5 range of wind speeds.

What are the levels of tornado?

The Fujita Scale

F-Scale Number Intensity Phrase Wind Speed
F0 Gale tornado 40-72 mph
F2 Significant tornado 113-157 mph
F3 Severe tornado 158-206 mph
F4 Devastating tornado 207-260 mph

What percentage of tornadoes are below F3?


Scale Wind speed estimate Frequency
F0 40–72 44.14%
F1 73–112 34.24%
F2 113–157 16.17%
F3 158–206 4.35%

Is a F6 tornado possible?

There is no such thing as an F6 tornado, even though Ted Fujita plotted out F6-level winds. The Fujita scale, as used for rating tornados, only goes up to F5. Even if a tornado had F6-level winds, near ground level, which is *very* unlikely, if not impossible, it would only be rated F5.
