Cold, stormy winter is coming to Canada, forecast

TORONTO – The climatological phenomenon known as La Nina is back, which means many Canadians can expect a cold and stormy winter, according to AccuWeather’s latest winter forecast.

La Nina, a cold weather phenomenon that normally occurs every three to five years, has surfaced for the second year in a row over the Pacific Ocean, the United States National Oceanic and Atmospheric Administration said in a report. Press release.

Temperatures across the country in January were high last winter, up to about 4.5 ° C above normal. But in February, temperatures swung and parts, including Edmonton and Winnipeg, experienced record lows, according to AccuWeather.

The western half of Canada will likely experience below average temperatures again this winter, along with more stormy weather, AccuWeather predicts, due to an amplified polar jet stream.

“The coming winter is expected to be quite stormy from southern British Columbia to the Canadian Rockies with plenty of opportunities for heavy precipitation and strong winds along the coast,” AccuWeather meteorologist Brett Anderson said on the company’s website. “Heavy snowfall is expected across much of the ski area, from the British Columbia Coast Ranges to the Rockies of western Alberta.

In central Canada, La Nina, combined with the polar vortex, could lead to freezing conditions.

“I believe we could see at least three extreme gusts of extremely cold air fall over the southern Prairies this winter,” Anderson said. During these events, he said temperatures could drop below -30 ° C. Average temperatures in the southern Prairies could also be 1.5 to 2 ° C cooler.

Ontario and Quebec can expect more snow, according to forecasts, as storms from the United States are expected to rise in their direction thanks to the polar jet stream.

While these provinces may experience increased snowfall, the eastern half of Canada is expected to experience above average temperatures.

Atlantic Canada is where the effects of La Nina could finally hit warmer-than-average waters of the Atlantic Ocean, AccuWeather reports, which could lead to a milder winter, at least initially.

“The greatest threat from powerful coastal storms in Atlantic Canada will come in February,” said Anderson. “The collision of cold westerly air with the unusually warm waters of the northwest Atlantic can result in rapidly developing storms with high wind and heavy precipitation from the Maritimes to Newfoundland.”
