Points saillants

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

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

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.

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.
