One person died and 10 were wounded as heavy storms swept through the north-western part of Poland on Saturday evening.
Two tornadoes hit counties in Kujawy-Pomorze and Wielkopolska provinces.
More than 100 houses were destroyed and about 400 hectares of trees were felled in Bory Tucholskie national park.
Power lines were also brought down leaving homes cut off and train services disrupted.
