Severe storms expected across southern Saskatchewan, Manitoba and north‑west Ontario on Monday
Meteorologist Chris Potter warns of heavy rain, large hail and damaging winds as a vigorous low‑pressure system rolls into the Prairies this Labour Day.
As the long‑overdue Labour‑Day weekend rolls around, many of us were hoping for a gentle breather after a scorching summer. Instead, the weather folks at The Weather Network are gearing up to warn us that a pretty nasty storm system is on the move.
Chris Potter, the network’s go‑to meteorologist, broke down the details on Monday morning. A deepening low pressure area, fed by warm, moist air from the south, is set to surge eastward across the Prairies. By mid‑afternoon, the rain‑making engine should be firing over southern Saskatchewan, spilling over into the north‑western part of Manitoba and even nudging the south‑west edge of Ontario.
What does that actually mean for anyone out and about? First, expect a lot of rain – think upwards of 20‑30 mm in some spots, enough to turn a quiet country road into a sloshy mess. That’s the kind of rain that can quickly overwhelm poor drainage and create local flooding, especially in low‑lying farm fields.
Second, the hail. The forecast calls for “large” hail – sizes ranging from golf‑ball to baseball‑ball diameter. If you’re driving, keep a wary eye on the sky; a sudden hail burst can pepper windshields, damage roofs, and certainly make a picnic a lot less pleasant.
And then there’s the wind. The models are showing gusts that could reach 90‑100 km/h in the most exposed areas. Those kinds of gusts are strong enough to snap tree branches, lift unsecured objects, and—if you’re in a mobile home—pose a serious safety risk.
So, what should people do? Simple, common‑sense steps work best. If you can, postpone any outdoor projects that involve ladders, roofs or heavy equipment until the storm passes. Secure loose items like patio furniture, trash cans and tools. And if you’re driving, pull over safely if hail starts pelting the windshield; a little delay is worth protecting your vehicle and your safety.
For those living in rural areas, keep an ear on local radio or a reliable weather app for real‑time updates. The storm could evolve quickly, and a warning that’s a few minutes old can feel like a lifeline.
While the forecast looks pretty solid, weather is notoriously fickle. Potter reminded viewers that “the details can shift by the hour, so stay tuned, stay prepared, and don’t take any chances.” A little extra vigilance on a holiday can keep the day from turning into a story you’d rather not retell.
Bottom line: a classic late‑summer thunderstorm is on the horizon, bringing heavy rain, sizable hail and potentially damaging winds across the Prairies. Heed the warnings, protect your property, and you’ll still be able to enjoy the long weekend once the clouds finally roll on.
