Regions

Chic-Choc Mountains.

Recent test results show that wind slabs are still sensitive to human triggering. Cold temperatures significantly slow snowpack stabilization.

Confidence

Moderate

Avalanche Summary

No new avalanches reported or observed

If you head into the backcountry, thanks for sharing your observations on the Mountain Information Network (MIN).

Snowpack Summary

At treeline and in the alpine, surface snow is strongly affected by wind, resulting in great variability in its distribution.

In wind-protected areas, the average depth of snow cover varies between 90 and 120 cm. Within this blanket, we find:

  • A thin layer of frost at a depth of around 20 cm.

  • A layer of facetted grains approximately 40 cm deep.

  • A melt-freeze crust at 60 cm.

Weather Summary

WEATHER FOR THE CHIC-CHOCS RIDGES AND SUMMITS

Temperatures will remain cold until the weekend.

Wednesday evening and night: Partly cloudy. Wind west, 20 to 40 km/h. Low -22.

Thursday: Mostly cloudy. Wind west, 20 to 40 km/h. High -17.

Friday: Sunny. Wind northwest, 25 to 50 km/h. High -15.

Saturday: Sunny. Wind northwest, 15 to 30 km/h. High -12.

For more details, see the Chic-Chocs alpine weather forecast.

Terrain and Travel Advice

  • If triggered, wind slabs avalanches may step down to deeper layers resulting in larger avalanches.
  • Watch for areas of hard wind slab on alpine features.

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.
