The summer storm season is underway in Saskatchewan with 19 tornadoes confirmed by Environment Canada, and three possible touchdowns.
Each year about 18 tornadoes are confirmed in the province, though the number of unreported tornadoes — as a result of not being seen — is likely higher.
Tornado season across the Prairies runs from April through to September.
Of the 19 confirmed tornadoes that touched down in the province, ten were landspout, nine were supercellular.
A landspout tornado is circulation created by updrafts and heat rising from the surface. The column of swirling air starts on the ground and can build up towards the sky. These tornadoes are usually weak and cause minor damage.
A supercell tornado is produced by supercell storm system or severe thunderstorm. The cell forms a wall cloud which lowers towards the surface and spawns a vortex of violently rotating winds. These tornadoes can be intense, dangerous and cause a lot of damage.
