Large swathes of Ontario, Quebec, and parts of Manitoba are bracing for what Environment Canada describes as a significant winter storm, with warnings issued for freezing rain and heavy snow as the weather system looms.
On Saturday, March 15, 2025, Environment Canada warned residents to prepare for this wet and wintry weather blast. The coldest conditions are expected near the Ontario-Manitoba border, particularly between Hudson’s Bay and Lake Superior, just west of Thunder Bay, Ontario, and east of Winnipeg. Freezing rain warnings were announced for this area, where several millimeters of ice buildup may create hazardous conditions.
The agency's warnings indicate rapidly fluctuated temperatures, combined with freezing rain and melting snow, are likely to result in dangerously slippery roads and sidewalks. Residents are urged to exercise caution, particularly when traversing these frozen surfaces.
Freezing rain is also on the radar for parts of Quebec, with forecasted rainfall measuring between 2 mm and 5 mm expected to accumulate in the northern regions of the province. Concurrently, much of southern Ontario remains under a special weather statement, which indicates significant rainfall is imminent.
Looking toward Toronto, substantial winds and rain are anticipated on Sunday, March 16, with wind gusts reaching up to 80 km/h and rainfall amounts potentially hitting 20 mm. The ground being frozen could impede the absorption of this rain, presenting additional concerns for pooling water on streets and properties.
On the same day, Environment Canada has also issued snowfall and flash freeze warnings for northern Ontario, affecting areas such as Timmins, Cochrane, Iroquois Falls, Gogama, Foleyet, Kirkland Lake, Temiskaming Shores, and Temagami. Heavy snowfall is projected to begin Sunday morning and last throughout the day and evening.
Local snowfall totals could reach as high as 15 cm, though certain regions may experience even greater accumulation, especially where mixes of rain, freezing rain, or ice pellets occur. A weather pattern referred to as a Texas Low is responsible for this significant snowfall as it traverses the area.
Residents must be prepared as temperatures are expected to plummet rapidly by Sunday evening. Following this drop, any accumulated rain, slush, and precipitation will likely freeze, contributing to dangerously icy conditions.
Travelers should remain alert, as the combination of heavy snow and sudden temperature changes could result in hazardous driving conditions, with potential difficulties on highways and local roads. Snow cover may render icy patches difficult to detect, leading to treacherous situations for drivers and pedestrians alike.
Overall, the impending winter storm serves as a reminder of the unpredictability of spring weather across the region, with various forecasts warning residents to stay vigilant and aware of their surroundings. Authorities recommend avoiding nonessential travel during the storm and adhering to road safety protocols to mitigate risks.
With such extreme weather warnings, it’s important for everyone to remain informed and prepared, as the changing climate patterns increasingly influence weather unpredictability. Stay tuned to local forecasts and heed all warnings issued by Environment Canada to navigate through these challenging conditions safely.
