Regions

Chic-Choc Mountains.

*** A special avalanche watch is activated for areas outside our forecast zone ***

Strong north-westerly winds will continue to displace new snow. Choose land below tree line.

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

Around 30 cm of snow have fallen in the mountains since Thursday evening. This snow was redistributed by the intense southerly winds, which then became strong northerly winds. In the alpine and at treeline, this new snow rests on a variety of old wind-affected surfaces: sastrugi, crust or superimposed slabs of different densities.

In areas sheltered from the wind and below treeline, we now find 50 to 70 cm of low-density snow resting on a well-consolidated snowpack. At the base, there is a layer of well-developed facets, especially where the mantle is thinner.

Terrain and Travel Advice

  • Keep your guard up as storm slabs may remain sensitive to human triggering.
  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Storm slabs in motion may step down to deeper layers resulting in large avalanches.

Problems

Storm Slabs

Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-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.

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.
