This same classification is also used by the National Weather Service. The National Weather Service of Quad Cities use a modified EF scale wording, which gives a new term for each rating on the scale, going from weak to catastrophic. [55] The table shows other variations of the tornado rating classifications based on certain areas.
The Fujita scale was adopted in most areas outside of the United Kingdom. [citation needed] On February 1, 2007, the Fujita scale was decommissioned, and the Enhanced Fujita Scale was introduced in the United States. [7] The new scale more accurately matches wind speeds to the severity of damage caused by the tornado. [8]
The International Fujita scale (abbreviated as IF-Scale) rates the intensity of tornadoes and other wind events based on the severity of the damage they cause. [1] It is used by the European Severe Storms Laboratory (ESSL) and various other organizations including Deutscher Wetterdienst (DWD) and State Meteorological Agency (AEMET) .

The Fujita scale, Enhanced Fujita scale, and the International Fujita scale rate tornadoes by the damage caused. [ 1 ] [ 2 ] In contrast to other major storms such as hurricanes and typhoons, such classifications are only assigned retroactively.
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 Xenia, Ohio, F5 tornado of April 3, 1974.This was one of two tornadoes to receive a preliminary rating of F6, which was downgraded later to a rating of F5. [1]This is a list of tornadoes which have been officially or unofficially labeled as F5, EF5, IF5, T10-T11, the highest possible ratings on the various tornado intensity scales.
The Fujita scale, Enhanced Fujita scale (EF), and International Fujita scale rate tornadoes by damage caused. The EF scale was an update to the older Fujita scale, by expert elicitation, using engineered wind estimates and better damage descriptions. The EF scale was designed so that a tornado rated on the Fujita scale would receive the same ...
