Regions

Chic-Choc Mountains, Chic-Chocs.

While traveling, pay attention to newly formed wind slabs as well as storm slabs that may still be reactive to rider traffic in some areas.

Confidence

Moderate

  • We are uncertain about alpine conditions due to limited field observations.

Avalanche Summary

Several avalanches that occurred on Sunday were reported on the Mountain Information Network (MIN). These avalanches, triggered by skiers, occurred at treeline on north-facing aspects.

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

Snowpack Summary

In some areas, up to 40 cm of new snow fell during the last storm. This snow rests on a variety of surfaces: wind-affected snow, powder snow, or sun crust.

A widespread melt-freeze crust about 2 cm thick is present at depths of 40 to 70 cm. A weak layer of faceted grains has developed on this crust on north to east aspects and is reactive in tests at treeline and in alpine terrain.

At mid-elevation, the average snowpack depth is around 140 cm.

Weather Summary

WEATHER FOR THE CHIC-CHOCS RIDGES AND PEAKS

After the weekend storm, a high-pressure system will bring fair weather over the next few days.

Monday evening and night: Snow showers. Accumulation of 5 to 10 cm. Northwest wind at 20 to 40 km/h. Low of -15 °C.

Tuesday: Mix of sun and cloud. Northwest wind at 10 to 30 km/h. High of -12 °C.

Wednesday: Sunny. West wind at 10 to 30 km/h. High of -8 °C.

Thursday: Sunny. South wind increasing in the afternoon to 70 km/h. High of 2 °C. Freezing level rising to 2000 m.

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

Terrain and Travel Advice

  • Wind slabs are most reactive during their formation.
  • Continue to make conservative terrain choices while the storm snow settles and stabilizes.

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.

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.
