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.
The rating of any given tornado is of the most severe damage to any well-built frame home or comparable level of damage from engineering analysis of other damage. Since the Fujita scale is based on the severity of damage resulting from high winds, a tornado exceeding F5 is an immeasurable theoretical construct.
The highest wind speed ever measured in a tornado, which is also the highest wind speed ever recorded on the planet, is 301 ± 20 mph (484 ± 32 km/h) in the F5 Bridge Creek-Moore, Oklahoma, tornado which killed 36 people. [122] The reading was taken about 100 feet (30 m) above the ground. [3]

Tornado intensity is the measure of wind speeds and potential risk produced by a tornado. Intensity can be measured by in situ or remote sensing measurements, but since these are impractical for wide-scale use, intensity is usually inferred by proxies , such as damage.
Timmer also noted that estimated wind speeds inside the tornado reached about 160-170 mph. The full data was released online to help aid further research from the historic intercept.
In a hurricane with winds that rotate counterclockwise, like Milton, tornadoes tend to form on the front end of a storm and on its right side — which is sometimes called the dirty side. This ...
This tornado was rated F5 by wind engineers on the basis of vehicles being carried long distances. Two pickup trucks were lofted for hundreds of yards, one of which traveled 1 ⁄ 2 mi (0.80 km) through the air. Peak structural damage was only of F2 intensity as two rural barns were obliterated. [60] The F5 rating was accepted by Fujita at the ...
