Regions

Kananaskis.

As we exit the drought, remember that a snow surface that's been exposed for a long time often leads to trouble down the road. Any new snow we get will sit on either a crust or windslab. In both cases, a good bond will take awhile to form.

Confidence

Moderate -

Weather Forecast

Bit of a ho hum kind of day tomorrow. It'll be cloudy all day with flurries starting in the morning. Winds will be light to moderate from the west. Temperatures will be around -4 all day, but as the evening approaches, they will begin to drop as the next system arrives.

Avalanche Summary

Nothing today.

Snowpack Summary

Flurries have left us with a few centimeters today. Nothing crazy, but we can't be too choosy these days. Every bit will help. We are in an extended period with no significant change in our snowpack. It remains well settled with a surface crust down low and wide spread windslabs everywhere else. There are likely isolated pockets of windslab in the alpine on all aspects.

Terrain and Travel

  • Avoid freshly wind loaded terrain features.

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.
