Lower Mainland residents are being urged to stay off the roads as a harsh weather pattern moves through B.C.'s southern coast.

For the second day, snowfall warnings are in effect in many areas, with up to 15 centimetres of the white stuff forecast for some southern Interior regions.

As much as 10 centimetres could fall over the Metro Vancouver area and parts of Vancouver Island. Other regions continue to deal with the fallout of the arctic front still hovering over British Columbia.

The harsh weather pattern is creating problems on the roads, with TransLink reporting major delays on some transportation routes. Some of the worst routes are in Coquitlam and Burnaby, where transit is moving slowly because of large volumes of snow. All HandyDART service is down to essential services in the Lower Mainland.

Hassles continue on the SkyTrain, where attendants are standing by at stations to de-ice the doors at Waterfront and King George terminals.

Police in West Vancouver are dealing with several accidents on the steep and winding roads on the Upper Levels Highway, including a jackknifed trailer and a multi-car pile-up.

Maintenance crews in Vancouver have added five additional trucks to the 22 that have been plowing and sanding city streets non-stop over the last several days.

Major routes across Greater Vancouver are slushy but smaller side streets are unplowed and are reported are icy and extremely slippery.

Problems in the Fraser

The situation isn't any better in the Fraser Valley, where the Albion Ferry connecting Fort Langley with Maple Ridge will remain closed until further notice due to ice floes forming on the Fraser River. The cancellation, which started Tuesday after the morning rush hour, could be as long as week.

The ice buildup along the docks on either side of the river made it difficult for the ferry to land, TransLink spokesman Drew Snider told CTV News.

The last time the Albion Ferry was closed due to ice was Dec. 2001.

With those normally using the ferry to get to work added to the longer highway commutes, transportation slowdowns expected on the Lougheed Highway, Highway 1, and other major routes in the Fraser Valley.

Further east, a crash closed the Coquihalla Highway until 9 a.m. with traffic being held in Hope and Merritt -- although traffic is getting through on the Okanagan connector between Merritt and Kelowna.

Drivers are also being warned to take caution if travelling along the Sea-to-Sky corridor, where a large volume of snow and ice on the roadway expected to continue into tonight.

The latest weather warnings come on the heels of a weekend storm that blasted the region with 12 centimetres of snow, sub-zero temperatures and high winds. There were 44 accidents in the Vancouver area on Saturday night and early Sunday, compared with the usual three.
