Points saillants

Pay particular attention to the start zones, where wind slabs may persist.

If in doubt, opt for a more conservative line, or explore sheltered areas, where the best snow is currently to be found.

    Isolated wind slabs of surprising depth can still linger in the start zones. Even if they tend to stabilize, triggering is still possible.

    Smaller wind slabs will be more widespread as a result of the new snow and moderate winds expected on Sunday night. Keep an eye on start zones and cross-loaded features.

Avalanche Summary

No new avalanches observed or reported in the last 24 hours.

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

Snowpack Summary

In the Alpine and on exposed features at treeline, the wind has strongly sculpted the landscape, creating great variability. The surface alternates between snowdrifts, hardened surfaces, scoured areas and pockets of lower density snow. In areas sheltered from the wind and below treeline, a few centimetres of fresh snow cover a thin, breakable crust. Beneath this layer, 20 to 40 cm of low-density snow rest on a well-consolidated snowpack. However, where the snowpack is thinner, a fragile layer of facets persists at the base. The height of snow varies between 120 and 220 cm.

Terrain and Travel Advice

  • Approach lee and cross-loaded slopes with caution.
  • If triggered, wind slabs avalanches may step down to deeper layers resulting in larger avalanches.
