Regions

Chic-Choc Mountains.

In alpine areas and treeline, the eastern and southern slopes are beginning to accumulate significant amounts of snow. At lower elevations, however, natural obstacles remain close to the surface.

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 and density. There is considerably more snow in the northern part of the forecast area (Mines versus Lyall).

The average snow depth at treeline varies between 90 and 120 cm. The cold weather of the past week has promoted the faceting process within the snowpack.

Weather Summary

WEATHER FOR THE CHIC-CHOCS RIDGES AND SUMMITS

A strong ridge of high pressure will settle over the Chic-Chocs on Saturday, before giving way to a weak trough of low pressure that will rapidly cross Quebec on Sunday.

Friday evening and night: Partly cloudy. Wind west, 20 to 40 km/h. Low -18.

Saturday: Sunny. Wind west, 20 to 40 km/h. High -12.

Sunday: Alternating sun and clouds. Accumulation of 1 to 3 cm. Wind southwest, 20 to 40 km/h. Maximum -10.

Monday: Flurries. Accumulation 10 to 15 cm. Wind southwest, 20 to 40 km/h. Maximum -10.

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

Terrain and Travel Advice

  • Wind slabs are most reactive during their formation.
  • Watch for areas of hard wind slab on alpine features.
  • Be cautious of buried obstacles, especially below treeline.

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.
