    Our observations concerning the effects of the storm are limited. Take particular care on the eastern and southern slopes. Recent strong winds may have formed large wind slabs.

Avalanche Summary

No new avalanches observed or reported.

If you are out in the backcountry, please share your observations on the Mountain Information Network (MIN).

Snowpack Summary

Around 30 cm of snow have fallen in the mountains since Thursday evening. This snow was redistributed by the intense southerly winds, which then became strong northerly winds. In the alpine and at treeline, this new snow rests on a variety of old wind-affected surfaces: sastrugi, crust or superimposed slabs of different densities.

In areas sheltered from the wind and below treeline, we now find 50 to 70 cm of low-density snow resting on a well-consolidated snowpack. At the base, there is a layer of well-developed facets, especially where the mantle is thinner.

Terrain and Travel Advice

  • Keep your guard up as storm slabs may remain sensitive to human triggering.
  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Storm slabs in motion may step down to deeper layers resulting in large avalanches.
