Warnings issued across B.C. for high winds, dangerous alpine snow

Strong winds and heavy alpine snow will make for dangerous conditions along B.C.'s highway passes late Wednesday and into Thursday.

After a snowy Tuesday across B.C.'s South Coast, another potent low-pressure system will make its way into the province late Wednesday, bringing strong winds and heavy alpine snow that will create extremely dangerous travel conditions.

Travellers planning to use the highway passes should consider postponing as we could also see blizzard conditions develop through the day.Closures were reported along the Coquihalla Highway Thursday morning, and drivers were being asked to avoid Highway 1 through Hope 'due to high winds knocking down trees and power lines', according to DriveBC. Be sure to also check highway conditions before heading out if you must.

Winter storm warnings have also been issued for several passes including:

  • Coquihalla Highway - Hope to Merritt

  • Highway 3 - Hope to Princeton

  • Okanagan Connector - Merritt to Kelowna

"Weather in the mountains can change suddenly resulting in hazardous driving conditions," Environment and Climate Change Canada (ECCC) warns. "Adjust to winter driving behaviour and use winter tires and chains."

Alpine snow brings extreme danger to mountain passes starting Wednesday night

A heap of heavy snow is forecast across B.C.'s mountains through Thursday, including the Coquihalla and Allison Pass.

The heavy snow will move in late Wednesday night and persist into Thursday morning. Folks should avoid all non-essential travel during this time, as we could see whiteouts and blizzard conditions develop east of the Lower Mainland due to the high winds that will also be present.
