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 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]
Frame-home structural damage cannot exceed total destruction and debris dispersal, which constitutes F5 damage. A tornado with wind speeds greater than 319 miles per hour (513 km/h) is possible, as the 1999 Bridge Creek-Moore Tornado did have 321 mph (517 km/h) winds, but that measurement was not near ground level.
The biggest tornado ever recorded touched down near El Reno, Oklahoma, on May 31, 2013, reaching a width of 2.6 miles and packing winds of 302 mph. Previously, the record was held by a tornado ...
The weakest tornadoes, or EF-0 and EF-1, have winds of up to 110 mph and typically cause relatively light damage. The most powerful, or EF-5, have winds above 200 mph and usually cause ...
The study’s authors argue that adjusting the EF5 wind speed threshold downward just 11 mph from 201 mph to 190 mph, or upgrading tornadoes with 190-200 mph estimated winds to EF5, would create a ...
Tornado damage to a house in Oklahoma County, Oklahoma, hit during the Tornado outbreak of May 10–13, 2010. Tornado intensity is the measure of wind speeds and potential risk produced by a tornado.
The calculated minimum wind threshold as stated beats both the 1999 Bridge Creek–Moore tornado and the 2013 El Reno, Oklahoma tornado for minimum possible maximum windspeed; however, the highest confirmed peak windspeeds are lower than the 1999 tornado. [56] [57] Winds were measured at 262–280 mph (422–451 km/h) using portable Doppler ...
