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. None of the tornadoes in the United States recorded before February 1, 2007, were re ...
The new scale more accurately matches wind speeds to the severity of damage caused by the tornado. [8] Though each damage level is associated with a wind speed, the Fujita scale is effectively a damage scale, and the wind speeds associated with the damage listed are not rigorously verified.
On May 6, 2023, version 0.99.9d was published, which changed it to a 9-step rating scale. [3] In this version, the wind speed damage indicator was introduced, which made it the first tornado intensity and damage scale to use measured wind speeds and Doppler weather radar measured wind speeds. [3]
According to the National Weather Service, the EF scale assigns a tornado a rating based on highest wind speeds occurring within the damage path. It's been used since Feb. 1, 2007. It's been used ...
The Enhanced Fujita scale measures a tornado's intensity on a scale of 1 to 5 based on its wind speed estimates and resulting damages.

Late-May 1998 tornado outbreak and derecho – DOW recorded maximum wind speeds at 264 mph (425 km/h) at 160 ft (49 m) above ground level, which the NWS classified at almost ground level. Such wind speeds would fall well into the EF5 range on the Enhanced Fujita Scale, though the maximum damage intensity observed in the town of Spencer was F4.
How are tornadoes rated? The Enhanced Fujita Scale classifies tornadoes into the following categories: EF0: Weak, with wind speeds of 65 to 85 mph. EF1: Weak, 86 to 110 mph. EF2: Strong, 111 to ...
