Regions

Chic-Choc Mountains.

The snowpack needs time to find its new balance after the mixed weather from the past few days.

Confidence

Low

Avalanche Summary

A size 2 avalanche was accidentally triggered by users in the northern couloirs on Hog's back. Otherwise, very few field observations since yesterday.

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

Snowpack Summary

The weather cocktail of the last few days brought changes to the upper snowpack, but thanks to the snow received at the end of the storm, the gliding conditions are still decent. In the alpine and in exposed areas at treeline, the 20 to 25 cm of storm snow was redistributed by the strong winds towards the northeast to south aspects. This snow overlies a crust left by the last system in leeward areas, and this crust is exposed on windward aspects. Below treeline, 20 to 30 cm of light snow sit over the rain crust.

The snowpack is generally wet under this crust, and it will be interesting to see how it will evolve with the cold temperatures of the next few days. Facets are still found at the base of the snowpack. The height of the snowpack varies between 100 cm and 200 cm.

Terrain and Travel Advice

  • Wind slabs are most reactive during their formation.
  • Keep your guard up as storm slabs may remain sensitive to human triggering.
  • Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.

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.

Loose Dry

Loose Dry avalanches are the release of dry unconsolidated snow and typically occur within layers of soft snow near the surface of the snowpack. These avalanches start at a point and entrain snow as they move downhill, forming a fan-shaped avalanche. Other names for loose-dry avalanches include point-release avalanches or sluffs.
