Regions: Kananaskis.

The drought continues with no end in sight. Generally stable conditions, but use caution in steep, unsupported convexities and shallow snowpack areas. The best skiing is in sheltered locations at lower elevations.

Confidence

Good

Weather Forecast

No precipitation is in the forecast. Alpine temperatures should climb to -7 on Tuesday, with moderate to strong N winds.

Avalanche Summary

Nothing new.

Snowpack Summary

Surface hoar up to 5mm in sheltered areas at 2300m and below. Surface facetting continues. Midpack is loosing strength due to continued cool temperatures promoting facetting. Condition of November rain crust is highly variable (still a crust in some areas, facetted out in others) and did produce shears in multiple field tests today.

Avalanche Problems

Wind Slabs

Wind slabs of varying thickness are present in the Alpine on all aspects, especially along ridgelines. Buried wind slabs are also present on N and E aspects down 25 to 55cm in the snowpack.
Avoid lee and cross-loaded terrain near ridge crests.>

Aspects: All aspects.

Elevations: Alpine.

Likelihood: Unlikely - Possible

Expected Size: 1 - 4

Deep Persistent Slabs

This layer is still a concern despite the lack of activity. In most areas at and above treeline we have a generally "deep" snowpack, however shallow areas will be found in the alpine. Treat these variable areas with caution.
Be aware of thin areas that may propagate to deeper instabilites.>

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible

Expected Size: 3 - 6
