Regions

Chic-Choc Mountains.

The wind has affected the snow right up to tree line. Beware of wind-loaded areas, especially on convexities and slopes without downhill support.

Confidence

High

Avalanche Summary

No new avalanche was reported or observed.

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

Snowpack Summary

In the alpine, the new snow (around 10-12 cm) have been wind blown and formed new windslabs. There is significantly more snow on the southern and eastern slopes. North and west-facing slopes are mostly free of snow, apart from couloirs and other depressions.

At and below treeline, in areas protected from the wind, 15 to 25 cm of low-density snow cover a layer of dense snow. The latter rests on 2 to 10 cm of facets that have developed on top of the New Year's Day melt-freeze crust. At these elevations, the best snow is found on the northern slopes.

The average height of the snowpack is approximately 100 cm, but varies greatly according to aspect and elevation.

Weather Summary

Synopsis: Cloudy with light snow showers on Monday, then fairly sunny with comfortable temperatures for the rest of the week.

Sunday evening and night: Becoming cloudy overnight. Wind northeast, 30-40 km/h. Low -15.

Monday: Cloudy. Light snow, accumulation of 1 to 2 cm. Wind northeast, 30 to 50 km/h. High -11.

Tuesday: Clearing in the afternoon. Wind 20 to 30 km/h from the northeast. Maximum -6.

Wednesday: Alternating sun and clouds. Wind 10 to 20 km/h from the northwest. Maximum -4.

Terrain and Travel Advice

  • Wind slabs are most reactive during their formation.
  • Be careful with wind slabs, especially in steep, unsupported and/or convex terrain 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.
