The mercurial weather this winter has brought us is also bringing a danger of avalanches across widespread areas in southern B.C. and some parts of Alberta.

On Thursday, Jan. 20, Avalanche Canada and Parks Canada issued a Special Public Avalanche Warning across numerous forecast regions in the two provinces, urging backcountry users to be especially cautious this coming weekend.

Warm temperatures and lots of sunshine are expected for the coming weekend, which will have a destabilizing effect on the snowpack. This special warning is in effect immediately and will apply through to the end of Monday, Jan 24.

The combination of this snowpack structure and higher temperatures will make natural and human-triggered avalanches much more likely.91裸聊视频�

The warning applies to the North and South Columbias, Purcells, Kootenay Boundary, and Glacier, Banff, Yoho, and Kootenay National Parks. It also applies to an area within the Sea-to-Sky and South Coast Inland regions, from Squamish to Pemberton.

Floyer said there have been several close calls reported recently, with many large avalanches running the full extent of their paths.

91裸聊视频淭here is a lot of uncertainty with these weak layers. While we have targeted an area where we think there is a higher risk of triggering these deep weak layers, we also urge backcountry users in adjacent regions to exercise caution during this warming period.91裸聊视频�
