Regions

Chic-Choc Mountains.

When the danger rating is moderate, human-triggered avalanches are possible. Carefully assess the snowpack and terrain; identify any terrain features of concern.

Confidence

Moderate

Avalanche Summary

No new avalanches have been observed or reported.

If you're out in the backcountry, please share your observations on the Réseau d'Information en Montagne (RIM).

Snowpack Summary

30 cm of recent snow, dry above 900 m, resting on a generalized refreeze crust. Conditions are highly variable in the alpine and at treeline (presence of rocks, ice and wind-blown snow). Below treeline, up to 50 cm of recent snow is present on the refreezing crust. The upper part of the snowpack, up to 80 cm deep, is moist. The middle of the snowpack consists of alternating well-consolidated snow and refreezing crust.

At mid-mountain, the depth of the snowpack varies from 80 to 170 cm.

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.
