Chic-Choc Mountains.

*** A special avalanche watch is activated for areas outside our forecast zone ***

Be vigilant in areas where snow has been accumulated by the wind. Avalanches could be triggered by a rider.

Confidence

Moderate

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

Since Thursday evening, 40 cm of snow have accumulated in the mountains. In the alpine and at treeline, the western and northern slopes have been swept by the wind, leaving a hardened surface or one strewn with obstacles. The eastern slopes, on the other hand, have new wind slabs. Recent winds have also affected the snow, reaching below treeline in places.

The middle of the snowpack is well consolidated. At depth, a layer of well-developed facets is present, particularly in areas where the snowpack is thinner.

Terrain and Travel Advice

  • Wind slabs are most reactive during their formation.
  • Approach lee and cross-loaded slopes with caution.

Problems

Wind Slabs

Wind Slab avalanches are the release of a cohesive layer of snow (a slab) formed by the wind. Wind typically transports snow from the upwind sides of terrain features and deposits snow on the downwind side. Wind slabs are often smooth and rounded and sometimes sound hollow, and can range from soft to hard. Wind slabs that form over a persistent weak layer (surface hoar, depth hoar, or near-surface facets) may be termed Persistent Slabs or may develop into Persistent Slabs.
