Weather Forecast

Light west winds persist through Thursday with alpine day time high temperatures around -7 and a mix of sun and cloud. Click here for the Avalanche Canada mountain weather forecast.

Snowpack Summary

Strong SW wind and warm temps have likely created windslabs in the alpine. The October 25 crust, sitting 0-40cm off the ground, remains a concern. This crust is most prevalent in deeper snowpack areas - found predominately on N-NE lee features. Faceting above and below this layer continues to weaken the lower snowpack.

Avalanche Summary

No recent activity has been reported.

Avalanche Problems

Wind Slabs

Strong winds have likely created windslabs .
If triggered the wind slabs may step down to deeper layers resulting in large avalanches.Test slopes before committing to them.

Aspects: North, North East, East, South East, North West.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 2

Deep Persistent Slabs

Most skiable slopes have this crust, assess the strength of this interface before jumping into any committing lines. See forecast details for more info on this layer.
Watch for whumpfing, hollow sounds, and shooting cracks.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible

Expected Size: 1.5 - 2.5
