Regions

Chic-Choc Mountains.

Be careful if you go into the alpine on Wednesday, as the wind slabs could still be reactive.

Confidence

Moderate

Avalanche Summary

A natural avalanche of size 2.5 was reported to us. It occurred early in on Tuesday morning in the Mélèze, on a southern slope.

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

Snowpack Summary

On Tuesday, the snow became moist up to 700 m of elevation. We can expect a refreezing crust on the surface by Tuesday evening. In the alpine and at treeline, there are a variety of wind-affected surfaces (rocks, hard-packed snow, snow accumulation). At all elevations, 40 to 60 cm of rather light snow resting on a well-consolidated snowpack. Significant presence of facets at the base of the snowpack (up to 60 cm), especially where the snowpack is thinner. Snowpack height varies between 120 and 220 cm.

Weather Summary

WEATHER FOR THE CRESTS AND SUMMITS OF CHIC-CHOCS

This week's menu includes a little more snow and temperatures close to seasonal normals.

Tuesday evening and night: Cloudy. 2 to 4 cm of snow. Winds 10 to 20 km/h from the southwest. Minimum -4C.

Wednesday: Mix of sun and clouds. Winds 15 to 30 km/h from the northwest. High -4C.

Thursday: Cloudy. Trace of snow. Winds 20 to 50 km/h from the southwest. Maximum -6C.

Friday: Intermittent snow. 5 to 10 cm of snow. Wind 15 to 30 km/h from the northwest. Maximum -4C.

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

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.

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.
