Tornado watches issued in Saskatchewan, Manitoba amid severe storm threat

Residents across parts of Saskatchewan and Manitoba are advised to monitor the forecast closely as severe weather, including the potential for a tornado, is expected to continue through late Wednesday evening. Check back regularly for updates.

A threat for severe storms on the southern Prairies popped up Wednesday afternoon, prompting tornado watches in Saskatchewan and Manitoba. Storms capable of producing heavy rain, strong winds and large hail target parts of southern Saskatchewan and Manitoba. The threat for tornadoes will persist into the late-evening hours on Wednesday.

Our environment in Saskatchewan and Manitoba could support strong, potentially violent tornadoes if a storm can break through the CAP, according to Rachel Modestino, a meteorologist at The Weather Network.

In the event of a tornado, or if a tornado warning is issued for your area, it is recommended you take the following actions: Go indoors to a room on the lowest floor, away from outside walls and windows, such as a basement, bathroom, stairwell or interior closet. Leave mobile homes, vehicles, tents, trailers and other temporary or free-standing shelter, and move to a strong building if you can. As a last resort, lie in a low spot and protect your head from flying debris. Lightning kills and injures Canadians every year. Remember, when thunder roars, go indoors!
