Extreme cold warnings are plaguing seven provinces and two territories across Canada with areas facing wind chill values near -50 as winter’s weather intensifies this week.

Western Canada

In northern Alberta, the extreme cold will see wind chill values between -40 and -45 that will end by Monday evening, according to CTV Your Morning’s meteorologist Kelsey McEwen.

Residents in southern Manitoba will brace for wind chill values in the -44 to -50 range Monday morning due to a “bitterly cold Arctic air” over the region, Environment Canada said.

The extreme cold will taper down on Tuesday as a weak low-pressure system moves through the area, it added.

Ontario and Quebec

Many areas in Ontario, including Lake Huron and Georgian Bay stretching to the north, are under prolonged extreme cold warnings, with wind chill values hovering around -40, Environment Canada said.

These communities will see cold weather continue into Wednesday, where areas on the shore of Lake Superior are expected to see frigid temperatures cease on Tuesday.

The weather agency has also issued a snow squall warning watch for Northern Huron County and surrounding areas, which is expected to bring 30 to 60 centimetres of snow until Wednesday.

Eastern Canada

New Brunswick residents will get a mixed bag of extreme cold and winter storms, Environment Canada warned.

The warning said the northwestern part of the province can expect -35 to -40 wind chill values Monday night through Tuesday morning. Temperatures will begin to moderate later in the week.

In the southeastern part, a winter storm warning is in effect with hazardous winter condition expected Monday morning and set to end Monday afternoon. Additional snowfall of 10 centimetres is forecast. The snow and winds may cause reduced visibilities in blowing snow, Environment Canada said.

In eastern and northeastern Newfoundland and Labrador, strong winds of up to 100 km/h are expected.

The weather agency also said a snow squall watch is issued for western and southern parts of the province spanning Monday night through Thursday.

Total snowfall could reach 10 centimetres or more with wind gusts of 50 to 70 km/h.

For Prince County, P.E.I., a winter storm warning is issued and could see 10 centimetres of snowfall along with blowing snow due to strong winds. Conditions are expected to improve Monday afternoon as snowfall rates begin to ease.

The Territories

In Sachs Harbour of Northwest Territories, a blizzard warning will bring wind gusts of up to 70 km/h and near-zero visibility in blowing snow. Conditions are set to slowly improve Monday morning.

A blizzard in Clyde River and Naujaat – communities in Nunavut – will continue Monday as a low-pressure system passes by to the east. Northwest winds gusting to 90 km/h will give near-zero visibility in snow and blowing snow.

The blizzard is set to end early Monday evening.
