Periods of snow or rain are expected Tuesday and Wednesday, with daytime highs around 5 C and overnight lows dipping down to – 3 C.
On Thursday, the first day of December, there’s a good chance of snow flurries in the morning, and at night when the mercury is expected to drop to – 6 C.
That means Vancouver will be opening five extreme weather response shelters (for temperatures that feel like zero or colder) in addition to the five temporary shelters that open every night from Nov. 1 to March 31. If the temperature feels as low as – 5 C, the city will also open five warming centres.
Elsewhere in B.C., Environment and Climate Change Canada has issued a dozen snowfall warnings or winter storm watches for communities in the southeast and the northern parts of the province.
A Pacific frontal system is expected to sweep through the B.C. Interior this weekend, bringing heavy snow and strong winds before it tapers off on Sunday.
Snowfall warnings have been issued for parts of the Boundary, East Columbia, Kootenay Lake, Shuswap, West Columbia and West Kootenay and Peace River regions.
Winter storm warnings have been issued for parts of Fraser Canyon, Fraser Valley, Nicola region, the Okanagan Valley, Similkameen and South Thompson areas.
The weather office says the storm is expected to bring up to 25 centimetres of snow.
The agency warns drivers that heavy snow is also expected in the coastal passes and combined with gusting winds, it will create poor driving conditions.
The most challenging drives this weekend will be for those travelling from the Interior to the coast, according to Kelly Sonnenburg, a meteorologist at The Weather Network.
Sonnenburg said the Coquihalla Highway is expected to receive between 20 to 40 centimetres of snow with some icy precipitation mixed in.
“With temperatures well below the freezing mark most, if not all, precipitation will fall as snow,” said Sonnenburg. “It will have been over three weeks since Vancouver and the lower elevations had received snow, and this event could be much more significant than the last.”
This week, daytime highs will be in the minus double digits for many parts of central and northern B.C. and in the minus single digits in the south, the network said.
B.C. Housing announced earlier this month that the province would have 2,080 temporary winter shelter spaces and more than 480 extreme weather response shelters.
With the new spaces, more than 4,910 shelter spaces are open in 50 communities throughout the province, including permanent, temporary and emergency shelters, according to B.C. Housing.
