Avalanche Canada issued a special public avalanche warning on Dec. 13 for many mountain ranges in B.C., including the mountains in the Revelstoke area. The Revelstoke-based avalanche forecaster and safety organization issues special public warnings for a number of reasons, including during periods of higher-risk snow conditions, or busy times when less-experienced backcountry users are more likely to be in the mountains. Here is the text of the Dec. 13 special avalanche warning:
Avalanche Canada is issuing a Special Public Avalanche Warning for recreational backcountry users, in effect immediately until the end of day Sunday, December 16. The warning applies to the following forecast regions: Lizard Range and Flathead, Purcells, Kootenay Boundary, North Rockies, South & North Columbia, Cariboos, Vancouver Island, Sea-to-Sky, South Coast, South Coast Inland and Northwest Coastal.

After a prolonged drought in late November and early December, the province has been hit with a series of storms that have dropped a significant amount of snow. This new snow is not bonding well to the old surface that formed during the drought.
“Our main concern is that we are expecting the weather to clear on Saturday,” explains James Floyer, senior avalanche forecaster for Avalanche Canada. “After all this rain in the valleys, backcountry users are going to want to hit the alpine but that’s where the danger is greatest. There’s a very weak layer now buried anywhere between 60 and 150 cm. Any avalanche triggered on that layer will definitely be life threatening.”
Avalanche Canada warns anyone accessing higher elevation terrain to be aware of this hazard. This means skiers and boarders leaving ski resort boundaries and snowmobilers riding at or above the treeline. Everyone in a backcountry party needs the essential rescue gear — transceiver, probe and shovel — and know how to use it. And always check the current avalanche conditions at www.avalanche.ca.
