Regions

Kananaskis.

Very Good skiing at all elevations. Approach the alpine with caution for wind slabs.

Confidence

Moderate -

Weather Forecast

Wednesday and Thursday will be cloudy with light flurries. Temperatures in the alpine will be between -12c and -17c. Winds are expected to be from the SW at 30km/hr in the alpine. Cold moving in on Friday.

Avalanche Summary

Evidence of size 1 slab avalanche was seen in the Commonwealth area.

Snowpack Summary

The recent 50cm storm snow is showing evidence of a soft slab in some areas of tree line producing some hard test results on a density change 60cm down in the snowpack. The DEC 1, Nov 15 and Nov 5 crusts were easily found in a snow profile in the Commonwealth area at 2150m. Some faceting has started near the Dec 1 crust. In the alpine, expect more soft slabs at the surface, especially along ridge crests and cross loaded features. Take the time to dig and look at the upper snowpack.

Terrain and Travel

  • Approach lee and cross-loaded slopes with caution.
  • Avoid steep, unsupported slopes.
  • Recent wind has varied in direction so watch for wind slabs on all aspects.

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
