Environment Canada has issued heavy rainfall warnings for parts of Alberta and tornado watches for parts of Saskatchewan as a powerful weather system moves across the Canadian Prairies. Between 40 and 70 mm of rain is expected in Alberta through the weekend, while a surface trough moving north from Montana is expected to fuel severe thunderstorms in Saskatchewan.
Why Alberta faces flooding and infrastructure risks
The agency warned that already saturated ground, combined with above-normal rainfall totals this month, could lead to overland flooding, washouts, and damage to infrastructure and property. Localized flooding is likely, and some roads could become impassable according to the forecast alert.
In Edmonton, police on social media alerted that flooding had forced the closure of westbound lanes of Yellowhead Trail at 170 Street on Saturday, urging motorists to avoid the area and seek alternate routes.
Tornado and thunderstorm threats in Saskatchewan
Parts of Saskatchewan are facing a severe weather threat, with tornado watches and severe thunderstorm watches stretching across large portions of the province. Environment Canada stated that conditions are favorable for the development of severe thunderstorms capable of producing tornadoes, large hail, strong winds, and heavy rain.
Tornado watches are in effect across parts of southeastern Saskatchewan, including areas near Estevan and Weyburn. Additionally, severe thunderstorm watches and warnings cover Regina, Moose Jaw, and surrounding communities.
Expected weather timeline
The severe weather threat in Saskatchewan is expected to diminish later Saturday evening. However, forecasters say parts of Alberta could continue to see rain into next week.
