On 24 June 2021, a small outbreak of seven tornadoes formed across Europe. Severe atmospheric conditions over Central Europe generated an unusually powerful and long-tracked supercell storm over the South Moravian Region of the Czech Republic, producing conditions capable of sustaining a violent tornado for an extended distance.
In the evening of 24 June 2021, a rare F4-rated tornado tracked through the Hodonín and Břeclav districts, striking seven municipalities. The worst damage fell on the villages of Hrušky, Moravská Nová Ves, Mikulčice, and Lužice. At its widest, the tornado reached 3.5 kilometres, making it the broadest tornado ever recorded in Europe and the first confirmed violent tornado on the continent since 2017.
The tornado killed six people and injured 576, becoming the deadliest European tornado since 2001. Extensive structural damage was inflicted across multiple villages. The event prompted significant emergency response efforts in the Czech Republic and drew wide scientific attention, with the storm later rated IF4 on the International Fujita scale, the second-strongest rating ever assigned under that system.
