In sintesi

Snow tests have shown that windslabs rest on a fragile, reactive layer of facets. Assess the snow carefully before venturing onto a slope. For more details, see the ''Problems'' tab.

    We can hear a lot of whoumpfing as we move around the field right now. It's the facets (present on the New Year's crust) that are collapsing. Windslabs rest on these grains, and tests have shown that it's easy to initiate a fracture in this interface, and that it propagates easily. Be careful.

Avalanche Summary

No new avalanche was reported or observed. If you go into the backcountry, thanks for sharing your observations at [email protected] or on the Mountain Information Network (MIN).

Snowpack Summary

The distribution of the snow cover is extremely variable, ranging from 0 to 180 cm. In the alpine and at treeline, the southern and eastern slopes are bare of snow due to the strong winds of the last storm. The snow has been redistributed to the western and northern slopes. On these slopes, there are windslabs resting on facets that developed on the New Year's crust.

Terrain and Travel Advice

  • Approach lee and cross-loaded slopes with caution.
  • Use conservative route selection. Choose simple, low-angle, well-supported terrain with no overhead hazard.
  • Watch for areas of hard wind slab on alpine features.
