Another snowstorm coming to parts of southern Ontario

Another big snowfall is on the way for parts of southern Ontario.

Parts of cottage country were buried in snow on the weekend. The Muskoka area saw around 140 centimetres and Gravenhurst declared a state of emergency. The area lost power and drivers were stranded on Highway 11.

As of 7 a.m. on Monday, Highway 11 was closed in both directions between Huntsville and Orillia. It is expected to reopen later on Monday, according to the OPP.  

Snow is expected to continue Monday with Environment and Climate Change Canada issuing warnings for southwestern Ontario and the Barrie area.

The London area should expect the intense snow squalls to continue through Tuesday morning, the warning states.

After the weekend snowfall, additional accumulations of 30 to 50 centimetres, possibly exceeding 50 centimetres is expected for locations near Lake Huron by Tuesday morning, the warning states.

The northwesterly flow off Lake Huron will continue to result in intense snow squalls over the next couple days.

Peak snowfall rates could hit five to 10 centimetres per hour.

Drivers can expect poor to zero visibility at times in heavy snow. Snow squalls cause weather conditions to vary considerably; changes from clear skies to heavy snow within just a few kilometres are common. Travel is expected to be hazardous due to reduced visibility in some locations.

Road closures are likely. Power outages possible due to the heavy wet nature of the snow.

The OPP suggests people stay off the roads if possible.

In areas north of the GTA including Barrie and Collingwood around 20 to 40 cm of snow could fall by Tuesday morning.
