Regions

Chic-Choc Mountains.

Snow quality remains good at higher elevations, while the crust is widespread below 750 m. Caution is advised in wind-loaded areas on steeper slopes.

Confidence

Moderate

Avalanche Summary

A size 1 avalanche, estimated to have occurred 12 to 24 hours ago, was observed below “le Frigo” in the “Mur des Patrouilleurs” area.

If you are heading into the backcountry, please share your observations on the Mountain Information Network (MIN).

Snowpack Summary

In the alpine zone and at the treeline, a new, fragile crust is present on the surface up to 750 m. Conditions range from a hard frozen surface to accumulations of wind-blown snow.

The snowpack as a whole consists of alternating layers of well-settled snow and melt-freeze crusts.

At higher elevations, east and southeast aspects have better snow coverage, while north-facing slopes are scoured. Mid-mountain snow depth ranges between 60 and 190 cm.

Weather Summary

WEATHER FOR THE PEAKS AND SUMMITS OF THE CHIC-CHOCS

Monday evening and night: Clear. Northwest winds at 15 km/h. Low of -10°C.

Tuesday: Cloudy. Snow in the late afternoon. Southerly winds up to 15 km/h. High of 0°C.

Wednesday: Intermittent snow. Accumulation of 2 to 5 cm. Westerly winds at 25 km/h. High of -9°C.

Thursday: Intermittent snow. Accumulation of 2 to 5 cm. Westerly winds at 35 km/h. High of -8°C.

Terrain and Travel Advice

  • Carefully evaluate steep lines for wind slabs.
  • Pay attention to isolated wind affected features in the alpine, as well as cross-loaded features at treeline.

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.
