A blast of Arctic air is barrelling down on the West Coast of B.C., challenging low temperature records that have stood for 25 years.
The low is expected to dip to -10 C in the Vancouver area and -4 C in Victoria — the “warm” spot for the province.
The overnight low in the far northeast at Fort St. John is forecast at -30 C and in Prince George in the central Interior, -26 C.
The lowest recorded temperature in Vancouver for this date is -12.9 C, set in 1985.
Tuesday's forecast high of -6 C should smash the record low high for Nov. 23 of -1 C, also set in 1985.
The weather system brought more strong winds Monday night, knocking out power to more than 20,000 homes in the Fraser Valley.
The outages were located mostly in Chilliwack, Abbotsford and Langley. Hydro crews were expected to have the power back on sometime overnight.
The freezing weather system also dumped snow on the streets of Victoria and shut down some ferry routes between the islands.
Police in Victoria asked people to keep their vehicles off the street after a dump of snow made some routes impassable and led to a rash of traffic accidents.
Environment Canada issued a snowfall warning for southern Vancouver Island, the Gulf Islands and the Sunshine Coast, and road conditions are expected to worsen.
That prompted many businesses like Gateway Property Management to close for the day so their staff could avoid the afternoon rushhour, according to manager Nathan Enns.
“If the snow stops in the next hour, then…it's sort of a non-issue — the west coast over-response in terms of a little bit of snow. But if it keeps going, it's going to be a messy, convoluted rush hour going home this afternoon,” said Enns.
In Victoria, the city urged drivers to stay out of their vehicles in order to give public works crews time to clear major arteries.
A dozen smaller streets in the city are closed, in order to clear motor vehicle accidents, police said.
BC Transit said it cancelled buses to Royal Roads University along with Routes 53, and 66. A dozen other routes have been changed so buses could avoid slick areas.
The region's libraries closed at 3 p.m. All Catholic schools were closed, along with Camosun College.
Police in Saanich received so many calls that they had to ask people to stop calling 911 to report snow conditions.
Police were urging drivers to avoid the Transcanada Highway at Tillicum Road along with Carey Road, where multi-car pileups caused gridlock.
Galiano, Hornby, Denman ferries cancelled
Elsewhere on the coast gusting winds carrying cool arctic air are expected send temperatures plunging to as low as minus 20 with the wind-chill factor.
Environment Canada forecast winds of up to 80 km/h over the southern section of the Strait of Georgia on Monday afternoon, and BC Ferries is advising travellers to check online schedules after the high winds forced the cancellation of some trips to Galiano, Hornby, and Denman Islands.
“Please be advised that due to extreme weather conditions forecasted for this afternoon we do anticipate possible sailing delays or cancellations between Tsawwassen and the Southern Gulf Islands,” the ferry service has advised.
The Queen of Burnaby's 11:15 a.m. PT stop at Sturdies Bay on Galiano Island was cancelled and BC Ferries recommends that customers plan ahead and choose to travel via Swartz Bay to the Southern Gulf Islands.
Further north, sailings between Hornby, Denman and Vancouver Islands were also cancelled on Monday morning.
