Watch for newly formed wind slabs in drifted areas at upper elevations and minimize exposure to cornices. Be prepared to back off terrain if the snow becomes wet from strong sun.
Recent snow and wind are expected to form fresh wind slabs that may be reactive to human triggering. Avoid freshly wind-loaded terrain features.
Cornices are large and looming along many ridgelines. They are capable of triggering large avalanches when they fail.
Wet loose avalanches may be possible on steep slopes exposed to strong sun.
Thursday night: Clear, moderate southwest wind with strong gusts, treeline temperatures near -7 C, freezing level dropping to valley bottom.
Friday: Sunny with increasing cloud in the afternoon, moderate southwest wind, treeline temperatures near-2 C, freezing level rising to 1800 m and dropping to 1200 m.
Saturday: Cloudy, 5-15 cm of snow, light west wind, treeline temperatures near -4 C, freezing level rising to 1500 m and dropping to valley bottom.
Sunday: Increasing cloud, light southwest wind, treeline temperatures near -3 C, freezing level rising to 1700 m and dropping to valley bottom.
In the neighbouring Kananaskis Country and the Lizard-Flathead regions, loose dry avalanches were observed up to size 2.
5-15 cm of recent snow has been accompanied with moderate southwest winds, forming fresh wind slabs in lee features that may be possible to human trigger. Cornices are large, looming, and capable of triggering avalanches when they fail.
The mid-pack is firm and well settled. Some faceted snow and a decomposing melt-freeze crust can be found near the base of the snowpack. Snow line is gradually creeping up to higher elevations.
Glide cracks releasing as full depth glide slab avalanches become more common in the spring and are extremely difficult to predict. Best practice is to avoid slopes with glide cracks.
