The Canadian Avalanche Centre has issued a special avalanche warning for B.C. Interior mountains.
The warning, which as issued Friday and remains in effect through to at least Sunday, is for the Northern Rockies, the Cariboos, Eastern Monashees, the Selkirk Mountains and the Purcell Range.
As a result, it applies to many popular backcountry destinations, including those accessed from Tumbler Ridge, Grande Cache, McBride and Valemount, Blue River, Wells and Williams Lake, Clearwater, Revelstoke, Nakusp and Invermere.
The avalanche danger in most of these areas has recently been rated "high," and there has been a widespread avalanche cycle, the CAC said in a statement. Avalanche activity is slowly decreasing, but the risk of large destructive avalanches remains significant.
"The number of avalanches occurring naturally, without an obvious trigger, is starting to taper off," said the CAC's public avalanche bulletins manager Karl Klassen.
"However, there are still several weak layers in the snowpack that can easily be triggered by the weight of a person on skis or snowmobiles. Those avalanches will likely be much larger and more destructive than what we were seeing only a few days ago."
Backcountry travellers are urged to stay on low angle, simple terrain during this warning period. Conditions are not expected to improve until next week after several days of cooler weather will begin to stabilize the snowpack.
Travellers also need to be equipped with shovel, probe and transceiver and the CAC strongly recommends that all backcountry users take an avalanche awareness course. Snowpack stability changes constantly throughout the winter; backcountry users need to check the avalanche bulletin regularly to keep informed of conditions in their area.
