Many of the weather advisories issued early Sunday morning remained in effect into the afternoon, impacting residents of several provinces and two territories.

Environment Canada is warning of heavy rain, bitter wind chill and a dumping of snow in several parts of the country.

On the East Coast, warnings in Newfoundland and Labrador advise of strong winds, with as much as 30 centimetres of snow possible, depending on where you live.

In one of the warnings, forecasters wrote, “Secure outdoor Christmas decorations and other objects that could be lifted by strong winds,” in addition to visibility issues expected Sunday into Tuesday in parts of the province.

Sections of P.E.I. and Nova Scotia are also under yellow winter storm or snowfall warnings, with total snowfall amounts of up to 40 centimetres possible, combined with wind gusts up to 90 km/h.

The wintry weather was expected to last into Monday for some spots in Atlantic Canada.

One area of Quebec is also under a yellow winter storm warning, with the forecast suggesting “hazardous winter conditions” overnight Sunday and into Monday near Îles-de-la-Madeleine.

A total of 17 weather advisories were in effect in Ontario as of Sunday morning, the majority of which involved possible snow squalls in an area spanning from London to Tobermory, and Barrie to Goderich.

Those warnings were for conditions on Sunday only, with snow squalls expected to weaken in the afternoon.

Heading west, residents of a large swath of southern Manitoba that includes the Winnipeg area were warned of extreme cold, but milder temperatures were expected later on Sunday. The previously issued warning was lifted by noon local time.

Yellow warnings issued in Alberta range from wind to freezing rain to snowfall, and have been issued for parts of the province including Edmonton, as well as along parts of the borders with B.C. and Saskatchewan.

Snow in some areas was expected to fall in two rounds: first on Sunday morning, then again Sunday night into Monday. The freezing rain was forecast to be over by the afternoon.

Rainfall continues to be an issue on the West Coast with parts of southern B.C. under rainfall warnings. Further north, Environment Canada’s forecasters expect snowfall and freezing rain from Sunday to Monday morning.

Up north, a yellow warning for parts of Yukon warns that with the wind, it might feel as cool as -50 to -55. Some areas, including Whitehorse, are also under snowfall warnings, and could see 15 to 20 centimetres by late Monday morning.

Three alerts in the Northwest Territories advise of blizzard conditions in areas along the Amundsen Gulf.

No weather advisories had been issued for New Brunswick, Saskatchewan or Nunavut as of 1:15 p.m. EST.
