Points saillants

Wind slabs still need some time to stabilize, and human triggering is still possible.

Look for wind sheltered slopes, where you'll find the best snow!

    Wind slabs of varying density sit on top of each other, creating inversions in the snowpack in some places. This has the effect of prolonging and increasing the reactivity of the wind slabs.

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

Saturday's mild temperatures favoured the settling of the snowpack, and the sun affected the steeper slopes on solar aspects. .In the alpine and at treeline, the wind has sculpted the landscape, creating great variability. The surface alternates between snowdrifts, pressed snow, scoured or snow accumulation. In areas sheltered from the wind, especially below treeline, this snow lies on a well consolidated mid-pack. However, a fragile layer of facets persists at the base. The height of the snowpack 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.
