Regions

Kananaskis.

Frigid temperatures remain. Plan your objectives wisely, a little exposure to the sun will make all the difference. Good ski quality with the addition of 30cm over the last 2 days

Confidence

High -

Weather Forecast

The cold will continue until Friday when we see a warm up. No new snow expected Wednesday and up to 18cm by Friday evening. Moderate SW winds

Avalanche Summary

Some loose dry sluffs in Steep E facing alpine terrain up to Sz 2 noted in the Goat range today. 

No new slab activity.

Snowpack Summary

10-15cm overnight adds to the 15cm from Monday. 30cm Storm snow now sits on top of the cold snap facets. There seems to be wide spread wind slabs (roughly 5cm thick) buried anywhere between 5-25cm in the Alpine and open Treeline. This is not showing any reactivity at this time.

Terrain and Travel

  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
  • Watch for areas of hard wind slab on alpine 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.
