Environment Canada has issued a winter weather travel advisory for northern Durham and York regions.

“Lake effect snow bands will affect areas southeast of Georgian Bay into Wednesday morning,” the notice reads.

“Travel may be impacted due to accumulating snow, particularly during the evening commute.”

The travel advisory is also in effect for Lagoon City, Washago and Orillia, with a snow squall advisory issued for other parts of Simcoe County.

“Flurries and snow squalls are forecast to move westward this evening with local snowfall amounts 20 to 30 cm possible tonight into Wednesday morning. Areas between Collingwood and Wasaga beach are most likely to see the greatest amounts,” it reads.

“Local blowing snow reducing visibilities to near zero will also be a concern. The snow squalls are forecast to taper off when the winds shift to southwest later Wednesday morning. Prepare for quickly changing and deteriorating travel conditions. Visibility will be suddenly reduced to near zero at times in heavy snow and blowing snow.”
