2021 South Moravia tornado

In the evening hours of June 24, 2021, a rare, violent, and deadly long-tracked tornado struck several villages in the Hodonín and Břeclav districts of the South Moravian Region of the Czech Republic, killing six people and injuring 576 others. This tornado is the widest on record in Europe, at 3.5 kilometres (2.2 mi) maximum width. The tornado struck seven municipalities, with the worst damage in the villages of Hrušky, Moravská Nová Ves, Mikulčice and Lužice.

This tornado was the strongest ever documented in modern Czech history and the deadliest European tornado since 2001. It was rated as an F4 on the Fujita scale and an IF4 on the International Fujita scale. This made it the first confirmed violent (F4+) tornado in Europe since June 2017, when an F4 tornado struck the village of Maloye Pes'yanovo in Russia, and the IF4 rating also made it the second strongest tornado currently rated on the IF-scale, following the rerating of the 1930 Montello and 1967 Palluel tornadoes from F5 to IF5 in May 2024. The tornado was part of a small outbreak of seven tornadoes that formed across Europe that day.
