A large portion of  Southwestern Alberta is under an avalanche warning.

The warning includes Kananaskis Country and Waterton Lakes National Park, Avalanche Canada’s South Rockies and Lizard and Flathead regions, as well as the southern part of the Purcells region.

In many areas a significant recent storm has doubled the depth of the current snowpack.

Winds have created dense slabs that lie on a weak base of sugary, faceted snow.

More snow, wind and warming temperatures are expected in the coming days before the weather breaks on the weekend.

Clearing skies and good riding conditions might entice people into the mountains.

Humans could be responsible for triggering large avalanches on the weekend."

Mike Koppang, Kananaskis Public Safety Team  Avalanche Canada, Kananaskis Country and Parks Canada says recreational backcountry users with little or no avalanche training or experience should avoid these areas.

Experienced backcountry recreationists are urged to travel on simple terrain such as small, low-angle, well-supported features with no large steep slopes or cornices above.

Although this warning applies to the regions listed above, recreational users are advised to exercise caution as potentially hazardous conditions exist in a number of areas throughout British Columbia and Alberta. Before travelling in the backcountry check Avalanche.ca for current avalanche information.

Everyone in a backcountry party needs to have an avalanche transceiver, probe and shovel. A two-day Avalanche Skills Training 1 course is the minimum training recommended for travelling in avalanche terrain.
