The outbreak produced ten tornadoes across the southern half of the province—an unusually high number of twisters in one day for this side of the border.

Tornadoes caused damage to homes, infrastructure
Widespread severe thunderstorms developed across southern Saskatchewan amid an unstable atmosphere on the afternoon of June 19. Several thunderstorms took advantage of the favourable environment to grow into supercells—thunderstorms with rotating updrafts.

A thorough investigation by the NTP revealed that the tornadoes included two significant EF-2s, three EF-1s, and five that received an EF-0 rating on the Enhanced Fujita Scale.
One of the tornadoes that hit Frobisher produced EF-2 damage with estimated winds of 195 km/h along a path measuring 12.5 km long. This tornado damaged trees, power poles, oil tanks, and grain bins, per the NTP damage assessment.
Another tornado that hit Kronau produced estimated winds of 185 km/h as it damaged a home, vehicles, trees, and crops in the area. This tornado remained on the ground for nearly 10 km and saw a maximum width of 680 m.
No injuries were reported in any of the tornadoes.
An unusually productive outbreak
Canada as a whole averages around 65 tornadoes in a typical year, with the Prairies hosting just over half of the country’s annual activity. We've seen 30 confirmed tornadoes so far this year, according to the NTP—17 of which touched down in Saskatchewan.

The outbreak on June 19 alone represents more than half of Saskatchewan’s typical tornado activity in an entire year.
It’s unusual for a province to record a tornado outbreak of this magnitude, owing to the favourable setup that developed over Saskatchewan on that mid-June afternoon.
The most recent tornado outbreak of this size unfolded in southern Alberta in June 2023.
Canada’s most prolific tornado outbreak struck southern Ontario on August 20, 2009. Thunderstorms that day produced 19 twisters throughout the region, causing significant damage and one fatality.
