Initially receiving an official EF3 rating based on damage, the El Reno tornado was subsequently upgraded to a radar-estimated EF5 rating, the highest on the scale, based on data from a mobile radar. The University of Oklahoma 's RaXPol mobile Doppler weather radar, positioned at a nearby overpass, measured winds preliminarily analyzed as in ...
The EF scale is also unofficially used in other countries, including China and Brazil. [2] [3] The rating of a tornado is determined by conducting a tornado damage survey. The scale has the same basic design as the original Fujita scale—six intensity categories from zero to five, representing increasing degrees of damage.
In 2001, tornado expert Thomas P. Grazulis stated in his book F5–F6 Tornadoes; "In my opinion, if there ever was an F6 tornado caught on video, it was the Pampa, Texas tornado of 1995". [14] In 2023, it was announced by the Storm Prediction Center and National Weather Service Norman, Oklahoma that the 1970 Lubbock tornado was originally rated ...

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.
The header color changes depending on the highest tornado rating provided; the name stays the same. Use |tornadoes= to indicate the number of tornadoes in this outbreak. This template supports two scales: the Fujita scale (priority) and the TORRO scale. These can be provided using the |fujita-scale= and |torro-scale= parameters, respectively ...
The original scale is named after Dr. Ted Fujita, who developed the system to help provide a wind estimate for the amount and type of damage that a tornado can produce. In 2007, the Enhanced ...
