Regions: Kananaskis.

Falling temperatures will help to "lock" the snowpack together. Travel will probably be fast, but challenging.

Confidence

Moderate -

Weather Forecast

Temperatures will begin to fall tonight with a morning low around -18. Despite the overnight plummet, daytime highs will quickly rise to -6 by mid afternoon. Winds will also taper tonight with only light winds at treeline for tomorrow. Skies will be a mix of sun and cloud with no snow expected.

Avalanche Summary

We saw numerous loose wet avalanches up to sz 2 today. Some were on steep alpine solar aspects, but the majority were low elevation dribblers.

Snowpack Summary

Temperatures have been above zero for a long time now. Expect moist snow up to 2100m, and possibly higher on solar aspects. After tonight's cooling, expect a crust in valley bottoms. Beyond that, there has been little change to the treeline and alpine snowpacks. Widespread windslabs on all aspects. 

Terrain and Travel

  • Avoid exposure to steep, sun exposed slopes, especially when the solar radiation is strong.
  • Cornices become weak with daytime heating or solar exposure.
  • Be careful with wind slabs, especially in steep, unsupported and/or convex terrain features.

Avalanche Problems

Wind Slabs

These will become less reactive at treeline, but remain reactive in the alpine. The cold will help stabilize them.

Aspects: All aspects.

Elevations: Alpine, Treeline.

Likelihood: Possible

Expected Size: 1.5 - 2.5
