Snow squalls could dump up to 30 cm across Simcoe County, Environment Canada says

Blowing snow creates reduced visibility on a road in Barrie, Ont.

Environment Canada is warning residents across Simcoe County to brace for intense lake-effect snow, with as many as 30 centimetres expected through Monday morning.

The snow squall warning was issued on Sunday just after 9 a.m. According to the national weather agency, the heaviest snowfall totals could come from the bands of snow originating off Georgian Bay."

Snowfall amounts will range from 15 to 30 centimetres, with the highest amounts expected in the most persistent lake effect snow bands.

“Visibility will likely be suddenly reduced to near zero at times,” the agency warned. “Road closures are possible. Prepare for quickly changing and deteriorating travel conditions.”

Environment Canada says conditions should gradually improve by Monday afternoon, though lingering flurries may continue midday.

Drivers are urged to use caution and be prepared for quickly changing weather.
