Regions

Kananaskis, Bow Valley, Highwood Pass, North 40, Spray - KLakes.

Flurries will continue to add a hint of fresh snow over the next couple of days. Not really enough to fix our ski quality problem, but also not enough to increase avalanche hazard.

Confidence

High

Avalanche Summary

Nothing new was noted today.

Snowpack Summary

Surface windslabs continue to be the most concerning issue in our snowpack. They are essentially widespread, but vary in thickness and density. Areas of hard slab are the most concerning as they are the most likely to propagate. There was some light snow today giving about 4cm, however that isn't enough to tilt the scales of ski quality or avalanche danger. In sheltered areas, or areas that haven't seen travel the snowpack is still very weak. While walking or skiing it isn't uncommon to punch to ground.

Weather Summary

Overnight low of -15, daytime high of -9. Flurries will carry on through the night with very light accumulation. Winds will continue to be light to calm.

More details can be found in the Mountain Weather Forecast.

Terrain and Travel Advice

  • Carefully evaluate big and steep terrain features before committing to them.
  • Avoid steep terrain, including convex rolls, or areas with a thin, rocky, or variable snowpack.
  • Be careful as you transition into wind-affected terrain.

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.
