ABSTRACT Wind storms belong to the most costly natural hazards in Poland. On 11–12 August 2017, a strong thunderstorm happened, which resulted in catastrophic damage in three provinces: Wielkopolskie, Kujawsko-Pomorskie and Pomorskie. This disaster has resulted in the death of six people, injuries to several dozen people and enormous property losses. The objective of this paper is to describe, analyse and learn from such a dangerous extreme weather event. Examples of buildings, with improved stiffness, are presented as the solution for better resistance of wind forces. The final aim is to help humans prepare for and deal with the consequences of severe wind storms in the future.
