Snowpack Summary

In the alp the wind has created both deep lee pockets of snow and in other areas removed the snow altogether. The much discussed Oct 25th crust can be found 40cm off the ground and buried, in some locations, by 80cm of wind transported snow.  The crust is most likely to be encountered between 2,700m-2,000m. Below treeline snow cover is very thin.

Avalanche Summary

No new activity observed or reported. Remember to share the conditions found on your trip this weekend with Avalanche Canada's, Mountain Information Network

Confidence

Due to the number of field observations

Avalanche Problems

Deep Persistent Slabs

Although currently dormant, it would be wise to assess the strength of the interfaces above & below the October 25 crust before entering committing lines. This layer exists on most skiable slopes.
Watch for whumpfing, hollow sounds, and shooting cracks.Ride slopes one at a time and spot for your partners from safe locations.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible

Expected Size: 1 - 2.5
