Communities near Lake Huron and Georgian Bay are under a snow squall warning as bands of lake-effect snow slowly move across the region.

Environment Canada issued the warning for Barrie, Orillia, Midland, Bruce Peninsula, Owen Sound, Blue Mountains and Sault Ste. Marie, where snow squalls are expected to reduce visibility into Monday night.

Environment Canada said snow squalls will be relatively stationary for a few hours, meaning the region will be hit with about 15 centimetres of snow.

Snowfall amounts may exceed 20 cm in some communities if the snow squalls remain stationary for more than a few hours, Environment Canada said.

Motorists should expect hazardous winter driving conditions, including snow-covered and slippery roads, and near-zero visibility in bursts of heavy snow.

As a result, Ontario Provincial Police are urging motorists to slow down and drive with extra care.

On Monday morning, OPP briefly closed Highway 11’s northbound lanes at Third Line in Oro-Medonte Township because transport trucks were unable to climb an icy hill.
