Regions: Kananaskis.

Wind slabs in open areas and good skiing in sheltered places. Approach the Alpine with caution.

Confidence

Moderate -

Weather Forecast

Friday will bring yet another windy day with strong Westerly winds. Temperatures will start to warm up to -1c with a mixed bag of sun, cloud and flurries.

Avalanche Summary

No new avalanches have been noted.

Snowpack Summary

Expect to find wind slabs in the alpine and loose snow in sheltered areas. The two layers that are being tracked right now are:

1. Several generations of wind slabs in the upper 40cm of the snowpack producing moderate to hard test results.

2.The November 5 crust is sitting about 50cm off the ground. You can find up to 10cm of facets sitting overtop of the crust and still producing test results on the facets. This layer is found all the way into the alpine.

Terrain and Travel

  • Avoid shallow, rocky areas where the snowpack transitions from thick to thin.
  • Be careful with wind loaded pockets, especially near ridge crests and roll-overs.
  • Approach lee and cross-loaded slopes with caution.

Avalanche Problems

Wind Slabs

Watch for windslabs in alpine areas in the upper snowpack. Gullies and ridgelines are common areas to find these issues. 

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

Elevations: Alpine, Treeline.

Likelihood: Possible - Likely

Expected Size: 1 - 2.5

Persistent Slabs

Recent test results indicate moderate to hard results on facets above the Nov crust layer.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1 - 3
