A huge winter storm is forecast to strike Ontario, dumping up to 40 centimetres of snow in some parts and wreaking havoc on the roads.
According to Environment Canada, snow is anticipated to arrive in southern Ontario on Sunday night and “spread rapidly northeastward through the day Monday.”
According to the weather service, snowfall will be heavy at times, with rates of a few centimetres per hour probable. Winds of up to 50 kilometers per hour are expected Monday afternoon, resulting in poor visibility due to blowing snow.
“Travel will likely be difficult due to the expected heavy snow,” Environment Canada said.
Regions like Niagara Falls, St. Catharines, Welland, Grimsby, Kingston, Ottawa, Peterborough, Brockville, Tweed, and Cornwall should be prepared for anywhere between 25 and 40 centimetres of snow.
Peak snowfall rates of two to five centimetres per hour are possible Monday morning into Monday afternoon, Environment Canada said.
Residents in these regions are being urged to avoid travel if possible.
“There may be a significant impact on rush hour traffic in urban areas,” Environment Canada said.
In Toronto, snowfall accumulations of 10 to 20 centimetres of snow are forecast Sunday night into Monday, however Environment Canada said “higher amounts can’t be ruled out.”
Pickering, Oshawa, Durham Region, Uxbridge, Beaverton, Vaughan, Richmond Hill,and Markham should expect similar snowfall amounts.
Monday is the first day Ontario students are slated to return to in-person learning across Ontario.
Conditions are forecast to improve by Monday evening as the snow comes to an end.
