List of tornadoes rated on the 2018 International Fujita scale
From Wikipedia, the free encyclopedia
This is a list of tornadoes that have been rated officially or unofficially on the International Fujita scale (IF-scale). The International Fujita scale was drafted in 2018 by the European Severe Storms Laboratory (ESSL) along with multiple European meteorological agencies.[1] As of 2023, the scale is not officially published for use, however, various tornadoes have received official/unofficial ratings under the scale. Since the scale is not officially in use, official ratings can only come from published academic papers or analyses from a government meteorological agency or from the European Severe Storms Laboratory and their partners. On May 6th, 2023, version 0.99.9d was published, which changed it to a 9-step rating scale.[2] This replaced the 12-step scale used to rate tornadoes on this list.
