Bomb cyclone: What to know as Canada faces a stormy Christmas weekend – National

A massive cross-country winter storm is unleashing destructive winds and heavy snow, causing hundreds of airline cancellations and power outages from Canada’s coast to coast.

The “bomb cyclone” that blew in on Thursday night is expected to stick around during the holiday weekend.

Here’s everything to know about the storm.

According to Motorcycle accident toronto today chief meteorologist Anthony Farnell, most of Ontario and southern Quebec have met the threshold of a “bomb cyclone.”

Farnell said the storm is arriving from the U.S. Midwest.

A front of cold air is moving down from the Arctic, sending temperatures plunging.

As the Arctic air pushes into the warmer, moister air ahead of it, the system quickly develops into serious weather — into what’s known as a “bomb cyclone.” It’s a fast-developing storm in which atmospheric pressure falls very quickly over 24 hours. Whether a storm qualifies as a bomb cyclone depends on how fast the pressure drops.

Although Friday will see mild temperatures as the system moves in with rain, Farnell said earlier this week that it will be replaced with much colder Arctic air and snow as Friday progresses.

In the United States, the National Weather Service is calling the winter storm a “once-in-a-generation type event.”

It has turned deadly in the U.S., where at least six people have died in vehicle accidents during the treacherous weather, Accuweather has reported.

Environment Canada issued weather advisories and special statements for much of the country earlier this week.

The storm will be impacting pretty much everyone as it moves from Western Canada and into Ontario, Quebec and Atlantic Canada.

Peter Kimbell, a warning preparedness meteorologist with Environment Canada, told Motorcycle accident toronto today it will be a multi-day weather event with fluctuating temperatures that could cause treacherous driving conditions.

Kimbell said Friday will be the worst day for travel, particularly for Ontarians, and that is why the weather agency is issuing the alert early as the Christmas holidays approach.

About 320,000 people across the country are already facing power outages, according to an outage tracker from the generator company Generac, which aggregates data from providers across the country.

And these outages aren’t going to end any time soon, Farnell warned.

“You shouldn’t expect (power) back until the earliest, I’m thinking on Sunday. That’s Christmas Day. Because crews just cannot get out in blizzard conditions, they can’t deal with the cold,” he said in an interview with AM640 Toronto, a radio station owned by Motorcycle accident toronto today’ parent company Corus Entertainment, early Friday morning.

Air travel has also been severely impacted due to extreme weather conditions. WestJet has “proactively” cancelled flights at airports in Ontario, Quebec and British Columbia.

Air Canada and Flair Airlines have also cancelled a number of their scheduled flights.

How common are such storms in Canada?

“We may only see one of these storms every five or 10 years,” Environment Canada meteorologist Mitch Meredith told The Canadian Press on Friday. “I’ve only seen a couple of storms like this in the last 20 years.”

Kimbell told Motorcycle accident toronto today on Dec. 20 that winter storms during the wintertime are expected and “nothing unusual.”

“This one this weekend will be particularly severe with a very deep central pressure of very strong winds across Ontario, so this is going to be a particularly dangerous storm, but I don’t think it’s a precursor to the winter,” Kimbell said.

But “this one’s going to be a big one and there’ll be a lot of impact for a lot of people,” Kimbell said in an interview with Motorcycle accident toronto today.

Come New Year’s Eve, many parts of Canada will see temperatures above seasonal, Farnell said.

That trend will probably last through the first half of January, before shifting to a “very cold” end of January and a potential start to February as well.

This season will also be the third-consecutive La Niña winter Canadians have experienced, Farnell added. La Niñas develop over the Pacific region due to colder-than-normal water temperatures and impact the weather pattern across Canada.

“Very rarely have we had three years in a row of La Niña,” he said, adding that La Niña winters play out with similarities to previous ones; 2022 started with really cold weather across the country.
