Damaged houses from the 2021 South Moravia tornado, which is currently tied as the strongest tornado ever rated on the International Fujita scale

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.

List[edit]

At least 40 tornadoes received an official or unofficial rating on the 2018 draft version of the International Fujita scale, with official ones in the Czech Republic, Denmark, Italy, Russia, Greece, Germany, Turkey, Poland, Norway, Sweden, Netherlands, Cyprus, Spain, Slovak Republic, and in France, and two unofficial ones in the United States.

IF4 June 24 2021 Czech Republic South Moravian Region Hrušky, Moravská Nová Ves, Mikulčice, Lužice 2021 South Moravia tornado – A violent and deadly tornado that damaged or destroyed 1,200 structures through multiple towns. In 2021, the Czech Hydrometeorological Institute (CHMI) published a survey and analysis report of the tornado, rating it F4 on the Fujita scale. In 2022, a joint report with the European Severe Storms Laboratory and other European meteorological agencies officially rated this tornado an IF4, with at least 14 different locations of IF4 damage occurring. In Mikulčice, a well-built brick structure was completely destroyed, which would warrant an IF5 rating. However, a rather weak connection between the roof and the walls was found, which prevented the damage to be assigned an IF5 rating. This location was assigned peak windspeed estimated at 380 km/h (236.1 mph).[4][5] ESSL, CHMI, SHMÚ, Charles University, Tomáš Prouza

IF4 (Unofficial) December 10 2021 United States Tennessee, Kentucky Woodland Mills (Tennessee), Cayce (Kentucky), Mayfield, Benton, Princeton, Dawson Springs, Bremen 2021 Western Kentucky tornado — A long-tracked wedge and ninth tornado spawned by the Quad-State supercell, that damaged, destroyed, or obliterated numerous structures along a path of 165.6 miles (266.5 km). This tornado was officially rated an EF4 on the Enhanced Fujita scale. During a thread on Twitter, Pieter Groenemeijer, the director of the European Severe Storms Laboratory, discussed the differences between the 2021 Western Kentucky tornado and the 2021 South Moravia tornado. In the thread, it was noted that one of the EF4 damage indicators would "probably be a D-class structure in the IF rating system, which gives a rating of IF4 when (almost) completely destroyed as seems to be the case here", meaning the 2021 Western Kentucky tornado would have probably been equivalent to at least an IF4 on the International Fujita scale.[6][7] Pieter Groenemeijer (Director of ESSL)
