Update: Between 4:30 and 5 p.m., Environment Canada updated weather alerts for Metro Vancouver and the Fraser Valley.
For southeast Metro Vancouver, which includes Surrey and Langley, snowfall of up to 10 centimetres is expected with five centimetres tonight and an additional five centimetres on the Saturday (January 18) morning.
Freezing rain is possible on Saturday morning.
Meanwhile in other areas of Metro Vancouver (including Burnaby, New Westminster, North Vancouver, West Vancouver, Maple Ridge, Coquitlam, Richmond, and Delta), a snowfall of two to five centimetres is expected tonight with an additional two to four centimetres in the morning.
While snowfall is anticipated to transition to rain, a delay in this transition would result in higher levels of snowfall.
In central, eastern, and western Fraser Valley (including Abbotsford, Chilliwack, and Hope), snowfall of two to five centimetres are expected tonight.
A transition from snow to freezing rain is expected between Abbotsford and Chilliwack on Saturday morning and to continue through the day.
Near Hope, snowfall is expected on Saturday until transitioning to freezing rain in the afternoon.
A total snowfall of 10 centimetres is anticipated by Saturday evening.
On the Coquihalla Highway from Hope to Merritt, and Highway 3 from Hope to Princeton via Allison Pass, freezing rain is expected on Saturday and could persist until Sunday.
Highways, roads, walkways, and parking lots are anticipated to become icy, slippery, and hazardous. All non-essential travel is recommended to be postponed until conditions improve.
An approaching storm is expected to hit the Lower Mainland tonight and will continue into Saturday.
Environment Canada issued a special weather statement at 5:40 a.m. today (January 17) that a Pacific storm is anticipated to make landfall tonight on B.C.’s south coast and will continue on tomorrow (January 18).
The storm is expected to bring a mix of snow, freezing rain, rain, and strong winds to Metro Vancouver and the Fraser Valley.
Affected areas will include Burnaby, New Westminster, West Vancouver, North Vancouver, Coquitlam, Maple Ridge, Surrey, Langley, Richmond, Delta, Chilliwack, Hope, and Abbotsford.
While snowfall is expected to begin late this evening on the south coast, warm air will change the snow to rain and may include a period of freezing rain as it transitions.
Most areas of Metro Vancouver and the Sunshine Coast are forecast to have changed to rain by midday on Saturday.
In the Fraser Valley, this transition could be delayed, resulting in higher snowfall amounts.
Due to cold winds from the B.C. Interior, temperatures will remain slightly below zero in the Fraser Valley, Howe Sound, and Whistler. The winds will create conditions conducive to freezing rain tonight and into Saturday.
Avalanche warnings for the Sea to Sky and South Coast (including the North Shore) regions will rise over the weekend to high danger levels by Sunday.
