Regions

Chic-Choc Mountains, Chic-Chocs.

The new snow and strong west winds have likely formed wind slabs reactive to skier traffic in the upper parts of slopes and below convexities. Travel cautiously and avoid areas where snow has accumulated due to wind.

Confidence

Moderate

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

Avalanche Summary

No new avalanches have been observed or reported.

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

Snowpack Summary

We have received between 5 and 10 cm since Tuesday evening.

In the alpine and at treeline, conditions are highly variable, with wind-hardened snow, pockets of powder, wind slabs of varying densities, and areas scoured down to bare ground, particularly on west- and south-facing slopes.

Below treeline, 20 to 40 cm of light snow overlies a progressively denser snowpack, down to basal weak layers of faceted grains and depth hoar.

On solar aspects, a sun crust is present 5 to 30 cm below the surface.

At mid-elevation, the average snowpack depth is around 130 cm.

Weather Summary

WEATHER FOR THE CHIC-CHOCS RIDGES AND PEAKS

A high-pressure system will move across Gaspésie on Thursday, bringing clearing skies and colder temperatures.

Wednesday evening and night: Partly cloudy. Northwest wind 30–50 km/h. Low -23°C.

Thursday: Sunny. Northwest wind 20–40 km/h. High -18°C.

Friday: Sunny. Southwest wind 10–30 km/h. High -7°C.

Saturday: Intermittent rain beginning around midday. Total accumulation around 10 mm. Southwest wind 50–70 km/h. High +2°C. Freezing level rising to 2,700 m.

Terrain and Travel Advice

  • Wind slabs are most reactive during their formation.
  • Stay off recently wind loaded slopes until they have had a chance to stabilize.
  • 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.
