Regions

Chic-Choc Mountains.

Even though the danger level is low, there is still a problem with windslabs.

The windslab problem is found in few places, due to the low level of general snow cover and the size of the skiable areas allowed.

Confidence

Moderate

Avalanche Summary

No new avalanches 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 and in wind-affected areas, on eastern and southern slopes, there is a succession of windslabs resting on facets.

A rain/solar crust, which formed on February 11, is present on steep solar slopes and below 500m altitude. The crust is covered by 5 to 15 cm of light snow.

The middle of the snowpack is well consolidated, resting on the December 30 combo of facets and crust. Facets and depth hoar are developing at the base of the snowpack.

Weather Summary

Synopsis: Milder weather returns on Wednesday. Mild temperatures, sunshine and light winds, that's what the week has in store for us

Tuesday evening and night: Clear. Wind northwest, 30-40 km/h. Low -22.

Wednesday: Sunny. Wind southwest, 20 to 30 km/h. High -10.

Thursday: Alternating sun and clouds. Wind south, 10 to 20 km/h. High -5.

Friday: Intermittent snow. South wind, 10 to 20 km/h. High -3.

Terrain and Travel Advice

  • Be careful with wind slabs, especially in steep, unsupported and/or convex terrain features.
  • Wind slabs may be poorly bonded to the underlying crust.
  • Even a small avalanche can be harmful if it pushes you into an obstacle or a terrain trap.

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.
