Regions

Chic-Choc Mountains.

New snow and wind will gradually increase the avalanche danger over the next few days. Be careful in areas recently loaded by the wind.

Confidence

Moderate

Avalanche Summary

No new avalanches observed or reported.

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

Snowpack Summary

In the alpine and on exposed features at treeline, we find a variety of surfaces affected by wind: Sastrugi, crust or multiple thin slabs of different densities overlying each other.

In sheltered areas and below the treeline, we find 25 to 40 cm of low-density snow on top of a well-consolidated core.

In general, cold temperatures continue to promote the faceting of the snowpack, especially where the latter is thinner.

Weather Summary

A low-pressure system from Texas brings snow on Thursday and Friday.

Wednesday evening and night: Clear, cloudy after midnight. Wind 10 to 20 km/h from the northwest. Low -23.

Thursday: Snow starting in the morning, 10 to 20 cm. Wind 40 to 70 km/h from the southeast, maximum -14C.

Friday: Snow flurries, 3 to 5 cm. Wind 40 to 60 km/h from the west. High -11.

Saturday: Sunny. Strong north-westerly wind. High -17.

For more details, see the Chic-Chocs alpine weather forecast.

Terrain and Travel Advice

  • Carefully evaluate steep lines for wind slabs.
  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.

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.
