Regions

Chic-Choc Mountains.

Currently, the greatest danger in the mountains is hitting objects on the surface or barely covered in snow, such as rocks or branches.

Confidence

High

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

The cold temperatures of the last few days have favoured the formation of near-surface facetting.

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: A weak low-pressure system over central Quebec will increase cloud cover in the Gaspé region from Thursday morning. A second low-pressure system will move in on Friday, bringing a few snow showers and, hopefully, 5 to 10 cm by Sunday.

Wednesday evening and night: Clear. Southwest wind, 20 to 30 km/h. Low -14.

Thursday: Alternating sun and clouds. Wind south, 10 to 20 km/h. Maximum -4.

Friday: Cloud cover. Accumulation of 2 cm of snow. Wind south, 10 to 20 km/h. Maximum -1.

Saturday: Intermittent snow. 2 to 4 cm of snow. Wind northeast, 10 to 20 km/h. Maximum -10.

Terrain and Travel Advice

  • Be cautious of buried obstacles especially below treeline.
  • 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.
