Regions: Banff Yoho Kootenay.

New windslabs are being formed in lee areas. Slabs can step down to deeper instabilities creating large avalanches that can run full path. Be patient, it will get better.

Weather Forecast

Warmer temps and steady moderate winds are forecast. Along with light snow over the weekend avalanche conditions should remain static.

Snowpack Summary

Up to 70 cm of recent snow with variable wind effect has put a dense slab over the persistent weak layers. In thicker snow pack areas, the Dec. 10th weak layer of facets is now down 100-150cm with a stronger snowpack below. In thin snowpack areas, the Dec.10th layer is mixed in with the October 26 basal facets and crust.

Avalanche Summary

Numerous avalanches were reported today on east and north facing slopes in the Banff area to size 2.5 Thursday. It is likely this was the result of warming temperatures and new wind loading.

Confidence

Avalanche Problems

Deep Persistent Slabs

The Oct. 26 layer is still very active. Some large natural avalanches are still occurring and human triggering is likely. This layer needs time to adjust to the load and this problem will be around for some time.
Be aware of the potential for wide propagations which could result in large avalanches.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Likely

Expected Size: 2 - 3.5

Wind Slabs

Use caution in lee and cross-loaded terrain near ridge crests.

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

Elevations: Alpine, Treeline.

Likelihood: Likely

Expected Size: 1 - 2.5
