Regions: Kananaskis.

Despite the lack of natural activity, the deep basal weakness is still a concern on northerly alpine features.  The probability of triggering a slide is low but the consequences remain high

Confidence

Good - The weather pattern is stable

Weather Forecast

Still no new precipitation in the foreseeable future.  Skies will be mainly clear with slowly rising temperatures and winds.  Daytime highs will be in the -15 degree range with overnight lows continuing to drop below -20 deg C.

Avalanche Summary

No new observed or reported.

Snowpack Summary

No change - surface facetting taking place.  Sun crusts are still present at all elevations on solar exposed aspects.  Terrain in the alpine and treeline elevation zones are highly variable with tregards to snowcover and conditon but wind slabs definitely dominate the landscape.  The deep basal weaknesses remain in place!

Avalanche Problems

Deep Persistent Slabs

The density of the slabs and the bridging effect above this layer are making it very hard to trigger an avalanche on this weakness but it is still potentially reactive in the right terrain. The probability is going down, but consequences remain high
Be aware of thin areas that may propogate to deeper instabilites.>Be aware of the potential for full depth avalanches due to deeply buried weak layers.>

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Unlikely - Possible

Expected Size: 3 - 6
