Regions

Chic-Choc Mountains, Chic-Chocs.

Spatial variability is currently very pronounced within our forecast area. The best riding conditions, as well as the safest conditions, are found below treeline. We recommend continuing to avoid areas where snow has been wind-loaded for the time being.

Confidence

Moderate

  • We are uncertain due to a limited number of field observations.

Avalanche Summary

Several avalanches were reported over the weekend on the Mountain Information Network. They occurred on north and northeast aspects and were 10 to 30 cm thick.

One of the avalanches that occurred on the Patrollers’ Wall is particularly noteworthy, as the surface snow that released stepped down and triggered a deeper buried weak layer.

If you head into the backcountry, thanks for sharing your observations on the Mountain Information Network (MIN).

Snowpack Summary

The extreme winds over the weekend significantly affected the snowpack in alpine terrain and at treeline. At the surface, conditions are highly variable, with wind-hardened snow, powder, wind slabs of varying densities, and scoured areas on west-facing slopes.

Below treeline, there are 20 to 40 cm of light surface snow resting on a progressively denser snowpack, down to weak layers of faceted crystals and depth hoar at the base.

At mid-mountain, the average snowpack depth is approximately 125 cm.

Terrain and Travel Advice

  • Strong wind is building wind slabs farther downslope than usual.
  • Avoid lee and cross-loaded slopes at alpine and treeline elevations.
  • Seek out wind sheltered terrain below treeline where you can avoid wind slabs and find great riding.

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.
