Lo esencial

Avalanche hazard is decreasing, but wind slabs in the Alpine are still a concern. Also, keep in mind the weak basal layers that have recently produced a few large avalanches.

Problemas de aludes

  • Wind Slabs

    These are improving. Sticking to well supported terrain will help stack your odds of not triggering it.

  • Deep Persistent Slabs

    Probabilidad
    Unlikely - Possible
    Tamaño
    1.5–3
    This layer is back in the game. Several full depth avalanches have occurred over the last several days. Thin spots and a weakening mid pack could spell trouble.

Avalanche Summary

Nothing new today, but observations were limited. Over the weekend several wind slabs and deep persistent slabs were observed in Alpine areas with debris running into Treeline and Below Treeline elevations.

Weather Forecast

The cold snap continues.  Another night of -30, followed by mostly sunny skies and temperatures near -17 for Tuesday. Winds will be light from the NW.

Snowpack Summary

Alpine areas are primarily wind effected with a mix of hard and soft wind slabs on all aspects. These tend to disappear as you descend into Treeline elevations. Overall the snowpack continues to facet, especially in shallow snowpack areas and at lower elevations. In valley bottoms the ski penetration is to ground unless you are traveling on an existing packed trail.
