Avalanche warning issued for Southern BC and Western Alberta

Warm temperatures and lots of sunshine are expected for the coming weekend, which will have a destabilizing effect on the snowpack

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.

“There are persistent weak layers in the mountain snowpack across most of southern BC and western Alberta,” said James Floyer, Forecasting Program Supervisor for Avalanche Canada. “This special warning targets regions where these layers have proven to be an issue. The combination of this snowpack structure and higher temperatures will make natural and human-triggered avalanches much more likely.”

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.

“There 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.”

Backcountry users should always check their regional avalanche forecasts at www.avalanche.ca. Everyone in a backcountry party needs the essential rescue gear—transceiver, probe, and shovel—and the knowledge to use it.
