Unusual cold in store for B.C.'s north, Lower Mainland this weekend: Environment Canada

Environment Canada is expecting unusually cold temperatures and frigid wind across northern B.C. and the Lower Mainland this weekend, warning conditions up north could decline to extreme cold and "dangerous" wind chillin the next week.

A series of special weather statements on Friday said Arctic air, blasting wind and plummeting temperatures will settle over the far north and stick around for several days.

"Temperatures will remain extremely cold through next week," said meteorologist Derek Lee,adding wind chill values could be "dangerous."

"It's likely that the coldest temperatures will be Monday to Wednesday."

Lee said the area from Peace Region to Fort Nelson could see overnight lows below 40 C. The Prince George and Cariboo areas could see overnight lows colder than 35 C.

The weather statements coverHaines Road, Atlin, Teslin, Cassiar Mountains, Dease Lake, Watson Lake, Muncho Lake Park and Fort Nelson in the far north.

Similar alerts are also in place further south, where cold winds areexpected to hitthe WillistonandPeace regions. Prince George could see temperaturesas low as 28 C over the weekend.

Further south, snow is in store for the Lower Mainland over the next few days.Vancouver is expecting a combination of rain and snow over the weekend and throughout much of next week, with a daytime maximum of 5 C on Tuesday.

Environment Canada saidprecipitation will fall Saturday as light flurries or showers. The amount will dependon temperature and elevation, but the agency said residents can expect roughly two to four centimetres of snow on average.

An Arctic front from the B.C. Interiorwill bring "a period of heavy flurries"to the South Coast on Sunday.

"The cold will linger up to mid-week next week," said Lee.

"The daytime temperaturesdon't really make it above freezing and even colder [during] the nights, so any precipitation that falls during this time, beginning this weekend, has a high chance of being flurries or snow."

Province asks drivers to stay home if conditions worsen

The province said drivers on the South Coast should stay off the road in poor conditions. If they must travel, they should pack an emergency kit and make sure their vehicle has proper snow tires.

"Drivers are reminded to plan ahead and drive according to weather and road conditions. Commuters should be prepared for delays and potential service disruptions on transit routes," it said Friday in a statement.

The statement said health authorities should be sharing information on shelters and warming centres across the province.

Lee said meteorologists aren't sure exactly when that snow will arrive, but up to fivecentimetres of fresh snow is possible for Metro Vancouver and up to 10 centimetres in the Fraser Valley.

Temperatures will drop tofiveor10 degrees below the seasonal average, the agency added.

People who live in any of the affected regionsshould continue to monitor the weather service's alerts and forecasts, Environment Canada advised.

Metro Vancouver politicians call for a 'snow summit'

A bigger dump of up to 25 cm blanketed the south coast and Vancouver Island at the end of November, leading to rush-hour crashes that blocked major roads.

Surrey Coun. Linda Annis was one of those trapped in the Nov. 29 gridlock. She says it took her 9.5 hours to get from Vancouver to South Surrey.

"[It was a]very, very long, frustrating trip. And for me, I quickly realized that I had no way to get home. All the access points to going over the Fraser River were closed or were stuck with vehicles,'' she said.

Annis and New Westminster City Coun. Daniel Fontaine are calling for a "snow summit'' to come up with ways to avoid a repeat. They want to involve the province, Metro Vancouver, municipalities, first responders and road maintenance contractors.

Annis and Fontaine wrote to Transportation and Infrastructure Minister Rob Fleming and the chair of Metro Vancouver's regional district pitching the idea last week but have yet to hear back.

The Ministry of Transportation and Infrastructure says in a statement it is aware of the request, but neither it nor Fleming had been formally invited to participate.

The ministry says it reviewed its response to the November snowfall and has worked with Lower Mainland contractors to improve deployment of plow and tow trucks.

"Ministry staff have also already reached out to their counterparts in Lower Mainland municipalities to discuss winter weather response, strengthen communication lines, and share information on our level of preparedness based on available weather forecasts,'' it said.
