A record 10 tornadoes were reported in Saskatchewan on Friday as a dangerous heat wave intensifies extreme weather across the Prairies.
Reports set the province’s single-day tornado record previously set in June 2025, and Environment Canada warned more tornadoes were possible as hot and humid conditions persisted.
“Yesterday we had 10 reports of tornadoes in Saskatchewan,” Environment Canada meteorologist Kayla Bilous told Global News.
The tornadoes came as a result of a prolonged heatwave over southern Saskatchewan and Manitoba, where heat warnings remain in effect.

Heat could bring humidity to 45 in Manitoba, Saskatchewan
“Essentially there is a large upper ridge over this area that is pushing very warm, moist air into our area,” Bilous said. “We expect to see some really high humidity readings this weekend and early next week.”

The agency has issued heat warnings for much of southern Saskatchewan and Manitoba, as well as orange level warnings for parts of southeastern Saskatchewan and southern Manitoba, where humidity values are expected to reach the mid-40s.

Prolonged heat is not limited to the prairies.
Heat warnings are also in effect for parts of northwestern Ontario near the Manitoba border, where temperatures are expected to reach the low to mid 30s and humidity values up to 42 by late Tuesday.
Although the tornadoes caused damage in some communities, Bilous said there were no reports of injuries or deaths. “There are definitely some cities that have been affected,” she said.
Asked about forecasts for the coming week, Bilous said the threat of severe weather had not yet passed.
“We are expecting more tornadoes in Saskatchewan again today.” Bilous said, adding that the heat will also continue.
“It looks like summer is in full swing and we will be in the 20s to 30s for most of the rest of the week.”
Environment Canada is urging residents to stay hydrated, limit outdoor activities during the hottest parts of the day and continue to monitor weather warnings as heat and the risk of severe storms continue.
