Regions

Chic-Choc Mountains, Chic-Chocs.

Although the danger rating has decreased to Moderate, it is still possible to trigger wind slabs in areas that have recently been wind-loaded. It is important to recognize these loaded zones and avoid them.

Confidence

High

  • The snowpack structure is well understood.

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

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, pockets of powder, wind slabs of varying densities, and scoured areas on west-facing slopes.

Below treeline, 15 to 30 cm of light surface snow overlies a progressively denser snowpack, down to weak layers of faceted crystals and depth hoar near the ground.

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

At mid-mountain elevations, the average snowpack depth is about 130 cm.

Weather Summary

WEATHER FOR THE CHIC-CHOCS RIDGES AND PEAKS

Cloud cover will increase on Tuesday as a system approaches from the west. Winds will shift to the southwest and temperatures will rise to around -10°C in the mountains.

Monday evening and overnight: A few clouds. West wind 20–40 km/h. Low -23°C.

Tuesday: A mix of sun and cloud. Southwest wind 30–50 km/h. High -10°C.

Wednesday: Intermittent snow. Accumulation of 4–6 cm. West wind 40–60 km/h. High -5°C.

Thursday: Sunny. Northwest wind 20–40 km/h. High -19°C.

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.
