Severe winter storm slams Quebec, Ontario

It's snowing. It's blowing. And it's very, very cold.

From eastern Ontario to the Maritimes, Environment Canada is warning of winter storm conditions that include snowfall,strong wind,extensive blowing snow and extreme cold.

This "snow, cold and wind" combination rarely occurs in Quebec, according toEnvironment Canada meteorologist Alexandre Parent.Usually, he said, the temperature rises during snow storms.

He has analyzed data going back decades for southern and central Quebec and "I cannot find a similar storm."

In 1920, he said there was a storm with similar characteristics that dropped about 30 centimetres of snow with temperatures fallingto 19 C.

In Quebec City, the temperature hovered around17CSunday afternoonand itwas18C in Montreal with snow accumulation expected to reach 15 to 25 centimetres in both regions.

But Quebec is not alone.

Toronto residents were digging out from under 10 centimetres of snow Sunday, expecting temperatures of 24 C by the evening.Wind chill values could feel as low as 38 overnight there.

In eastern Ontario, temperatures will only rise slightly to a high of16 C, with winds gusting up to 40 km/h and another seven to 12 centimetresexpected to fall by Monday morning.

Northern New Brunswick is bracing for 30 to 50 centimetres of snow expected with snow changing to ice pellets and freezing rain in the afteroon or evening.

The storm maydropas much as 30 centimetres in the Beauce region and more than 50 in the Gasp area.

There will be a risk of frostbite during the day and into the night Sunday with wind chill values hovering between 25 and32.

Authorities are urging drivers to postpone non-essential travel until conditions improve and sections of several highwaysand roads are closed due to weather conditions.

Toronto police said about 100 crashes were reported Saturday afternoon into Sunday morning,with drivers sliding into ditches, clumps of treesand other vehicles.

"Every street will be plowed by the end of the day," he said.

He told CBC that people should take public transit and leave their cars at home on Monday and that operations to remove the snow will begin at 7 p.m. on Monday evening.

Residents can monitor the city's Info-Neige app for updates on where the snow removal is taking place and what areas will be affected.

In Ottawa, an overnight parking ban willbe in effectbetween 1 a.m. and 7 a.m. Monday, as crews work toclear city streets.

Vehicles won't be allowed to park on the street during that time, but on-street parking permit holders are exempt, the city said. Free parking is being offered at all city-owned covered parking garages during that time.
