Lo esencial

The weather is providing great travel conditions but remain cautious around older wind slabs that could be sitting on weaker snow. Also pay attention to how the sun might be affecting south aspects at lower elevations.

    Wind slabs vary in age across the region but can be sitting on weaker crystals so triggering is still possible. Tread with caution on stiff, drum-like snow as firm wind slabs can be unpredictable.

Avalanche Summary

No new avalanches have been reported in this region since the weekend.

Snowpack Summary

Surface conditions are variable and include sun crusts, wind-affected snow, and in some places up to 10 cm of snow above surface hoar. Sheltered areas have 20 to 40 cm of soft snow from last week. This snow sits above a layer of surface hoar or decomposing crusts, that could develop into a problem when buried more deeply. The lower snowpack contains weak and faceted grains, but these layers have not recently produced avalanches.

Terrain and Travel Advice

  • Be careful with wind slabs, especially in steep, unsupported and/or convex terrain features.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.
