A formidable winter storm is poised to unleash a barrage of snow across southern Ontario, beginning Thursday and persisting through the weekend. This isn't a fleeting flurry; it's a prolonged event with the potential for significant disruption.
While major urban centers like Toronto, Peel Region, Oakville, and Burlington appear to be spared the worst, a vast area stretching from York and Durham regions northward to Georgian Bay is bracing for substantial snowfall. Forecasts predict accumulations of 30 to 50 centimeters, with the possibility of even greater amounts in localized areas.
The most intense period of snowfall is anticipated between Thursday night and Friday night, creating conditions ripe for near-zero visibility. Heavy snow combined with strong, localized winds will generate treacherous blowing snow, making travel exceptionally dangerous.
Lake effect snow off Lake Huron and Georgian Bay will be a key driver of this storm, intensifying Thursday morning and becoming firmly established by evening. Where these snow bands become stationary, exceptionally heavy accumulations are likely to occur.
The advisory emphasizes the potential for extremely hazardous travel conditions, with road closures a distinct possibility. Authorities strongly recommend avoiding non-essential travel and outdoor activities, and urge residents to prepare for disruptions to transportation, essential services, and utilities.
Southern Durham Region, including Pickering and Oshawa, could also experience significant snowfall, potentially exceeding 15 centimeters. Even areas that receive less snow will face challenging conditions due to strong winds.
Toronto, while largely avoiding the heaviest snowfall, may still encounter lake effect snow on Thursday. However, forecasters do not anticipate significant accumulations within the city itself. Breezy conditions are expected to persist through Friday as westerly winds gradually diminish.
The approaching storm serves as a stark reminder of winter’s power and the importance of preparedness. Staying informed and exercising caution will be crucial as this significant weather system unfolds.
