Avalanche Summary

No new avalanche was reported or observed. If you go into the backcountry, thanks for sharing your observations at [email protected] or on the Mountain Information Network (MIN).

Snowpack Summary

The distribution of the snow cover is extremely variable, ranging from 5 to 180 cm. In the alpine and at treeline, the southern and eastern slopes are bare of snow due to the strong winds of the last storm. The snow has been redistributed to the north-western and northern slopes. On these slopes, there are windslabs resting on facets that developed on the New Year's crust.

Below tree line, there is between 15 and 80 cm of very dense snow on the ground, making skiing possible in some places. The bottom and natural obstacles, however, remain very close.

Weather Summary

Synopsis: The high pressure system will affect us for another 24 hours before giving way to the next winter storm. We can expect 20 to 30 cm by Friday. Areas further east, such as Murdochville, could receive up to 40 cm.

Monday evening and night: Partly cloudy. Southwest wind, 20 to 30 km/h. Maximum -15C.

Tuesday: Alternating sun and clouds. Snow expected to begin in the evening. Wind south, 10 to 20 km/h. Maximum -10C.

Wednesday: Cloudy. 15 to 20 cm of snow. Wind north, 20 to 30 km/h. Maximum -8C.

Thursday: Cloudy. 5 to 10 cm of snow. Wind north, 20 to 30 km/h. Maximum -15C.

Terrain and Travel Advice

  • Approach lee and cross-loaded slopes with caution.
  • 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.
