Chic-Choc Mountains

Even if the rating is low, it doesn't guarantee absence of avalanche danger. Unstable wind slabs might persist in isolated spots, possibly sitting atop a crust ideal for sliding.

Be vigilant for indications of recent loading.

No new avalanches reported or observed.

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

Snowpack height is highly variable across the zone, and wind effects are strong in the alpine and at the treeline.

In areas sheltered from the wind, you can find between 10 and 20 cm of very low density snow. Sectors closer to the north coast were favoured.

Below 500m altitude, this new snow rests on a refreezing crust that had formed on Monday. The crust thickens and hardens as we lose altitude. On sunny slopes, the crust is present up to 1000m. On sunny alpine slopes, the crust is very firm, and ski crampons are essential. A thin layer of facetted grains is developing on this crust.

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

The average height is around 100 cm.

Synopsis: The cold, rather dry weather continues until Wednesday, when we'll be treated to milder temperatures in the mountains.

Monday evening and night: Partly cloudy. Wind northwest 20-40 km/h. Low -22.

Tuesday: Mostly sunny. Wind northwest, 25 to 45 km/h. High -20.

Wednesday: Sunny. Wind southwest, 20 to 40 km/h. High -6.

Thursday: Alternating sun and clouds. Wind southwest, 10 to 20 km/h. High -2. Freezing level at 500m.

• 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.
