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 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 ...

[11] [12] Several tornadoes since the Moore EF5 have reached the 200 miles per hour (320 km/h) wind speeds needed for a tornado to be classified as an EF5, including the 2013 El Reno EF3 tornado and 2015 Rochelle–Fairdale EF4 tornado, with wind speeds measured in excess of 295 miles per hour ...

The Philadelphia tornado marked the first instance of an F5 or EF5 tornado in Mississippi since the March 3, 1966, Candlestick Park tornado. Following another EF5 tornado that struck Smithville later on April 27, the outbreak marked the first known instance of two EF5 tornadoes on a single day in Mississippi. [15]
This Candlestick Park tornado is one of only four Mississippi tornadoes to receive either an F5 or EF5 rating, though a recent study has cast some doubt on whether recent EF4 tornadoes should be ...
