If you have plans to travel south this weekend, keep a close eye on the road and weather conditions and leave today if possible.
Diving is going to get more dangerous as the weekend approaches.
Environment Canada has issued a snow squall warning for the Highway 11 South corridor including Burk's Falls, Huntsville, Bracebridge, and Gravenhurst as a multi-day lake effect snow squall event begins this evening.
Expect locally heavy snowfall with accumulations possibly exceeding 30 cm by Friday night. Peak snowfall rates could reach 5 to 10 cm per hour. That means very poor visibility in bursts of heavy snow and local blowing snow.
Additional locally heavy snowfall will occur over the weekend.
Lake effect snow off Lake Huron and Georgian Bay is forecast to strengthen Thursday evening into Friday morning and will persist through the weekend.
As is common with lake effect snow, snowfall amounts will be highly variable. Some areas may receive well in excess of 50 cm by the end of the weekend.
Road closures are possible this weekend, especially over areas that receive multiple lake effect bands. Isolated power outages may occur due to the expected heavy wet nature of the snow.
Snow squalls cause weather conditions to vary considerably; changes from clear skies to heavy snow within just a few kilometres are common. Travel may be hazardous due to sudden changes in the weather.
Consider postponing non-essential travel until conditions improve.
