Avalanche Canada
Carefully evaluate steeper terrain for wind slabs, as there is potential for avalanches to step down to deeper weak layers.

Confidence
Moderate
Avalanche Summary
No new avalanche activity has been reported since the weekend.
Several natural and rider-triggered avalanches, up to size 2.5, were reported over the weekend. A number of these reports occurred on the weak layer from early December.
Snowpack Summary
Recent snow has been heavily wind-affected in exposed areas. A crust exists below 1250 m, making for challenging travel conditions.
A weak layer, buried in early December, of facets and a crust is down roughly 50 to 100 cm from the surface.
Weather Summary
Tuesday Night
Mostly cloudy. 10 to 20 km/h northwest ridgetop wind. Treeline temperature -7 °C.
Wednesday
Cloudy with up to 5 cm of snow. 40 to 60 km/h southwest ridgetop wind. Treeline temperature -4 °C.
Thursday
Cloudy with up to 5 cm of snow. 40 to 60 km/h west ridgetop wind. Treeline temperature -4 °C.
Friday
Partly cloudy. 30 to 50km/h northwest ridgetop wind. Treeline temperature -6 °C.

Terrain and Travel Advice
- Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
- If triggered, wind slabs avalanches may step down to deeper layers resulting in larger avalanches.
Problems
Wind Slabs
Expect stiffer and deeper deposits of snow on northeast and southeast facing slopes. Watch for steep convex rollovers, ridgetop entrances, and cross loaded features.
Aspects: North, North East, East, South East, North West.
Elevations: Alpine.
Likelihood
Expected Size
Persistent Slabs
A widespread crust with facets is buried 50 to 100 cm deep. Wind slabs may step down to this layer, producing large avalanches.
Aspects: All aspects.
Elevations: Alpine, Treeline.
