A messy start to what forecasters say will be a messy weekend.
Bruce and Grey Counties have declared a significant weather event.
In separate statements released this morning, officials say it is not a notice of reduced level of service or a road closure. It is a heads-up that it may take longer for roads crews to clear the snow due to how much is expected to fall.
Everyone is urged to use caution and allow yourself extra time to get to your destination.
There is a snow squall warning in effect for Bruce County and northern Grey County. There is a winter weather travel advisory up for Huron, Perth, and southern Grey County.
Flurries and squalls are expected to persist throughout the weekend with some localized amounts reaching 70 centimetres of snow accumulation.
The Weather Network's modelling of the storm system suggests the lake effect snow will fall throughout the weekend, making travel extremely dangerous in those squalls.
The weather forecasting agency suggests depending on the wind, the bands of snow blowing off the lake could be thick and persistent, so some areas could see thigh-high snow while others just a few centimetres.
In those heavy bands of snow, the Weather Network warns travel could be all but impossible.
Environment Canada is urging people to postpone travel until conditions improve.
