Regions

Chic-Choc Mountains.

Although the danger rating has been reduced to moderate, avalanches can still be triggered by human intervention.

Confidence

High

Avalanche Summary

No new avalanches were observed or reported today.

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

Snowpack Summary

Following Tuesday's thaw, a refreezing crust formed only at low elevation (below 300 m). In the alpine and at treeline, a variety of wind-affected surfaces were observed (rocks, hard snow, snow accumulation). At all elevations in wind-protected areas, 30 to 50 cm of fairly light snow lies on top of a well-consolidated snowpack. A significant presence of facets is found at the base of the snowpack (up to 60 cm), especially in areas where the snowpack is thinner. The height of the snowpack varies between 120 and 220 cm.

Terrain and Travel Advice

  • Avoid steep, rocky, and wind-affected areas where triggering slabs is more likely.
  • If triggered, wind slabs avalanches may step down to deeper layers resulting in larger avalanches.

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.
