Regions

Chic-Choc Mountains, Chic-Chocs.

The significant variability between the northeast and south of the forecast area complicates regional forecasting. The magnitude of the avalanche problem appears to be much greater at the Madeleine mines than in the rest of the forecast area.

Regardless of your destination, exercise caution when approaching leeward slopes and slopes with lateral loading.

Confidence

Moderate

  • We are uncertain about forecast snowfall amounts.
  • We are uncertain due to the variability of wind effect on the snowpack.

Avalanche Summary

No new avalanches reported or observed.

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

Snowpack Summary

Since Monday, approximately 15 cm of very light snow has fallen on the southern part of the forecast area (Lyall, Hog's Back, Albert) and up to 30 cm in the Madeleine Mines sector. There is therefore significant spatial variability across the area.

This snow has had difficulty settling on the alpine slopes of Albert. The south and east slopes have very firm surfaces. There are only a few isolated pockets of accumulation in areas of lateral loading. The west slopes are generally bare.

The alpine sector and the tree line of the Madeleine Mines have been loaded much more significantly.

Below the tree line, as well as in areas sheltered from the wind, there are 20 to 40 cm of light snow resting on a gradually denser blanket. Here again, the distribution remains highly variable depending on the sector.

At mid-mountain, the average snowpack depth is approximately 120 cm.

Weather Summary

WEATHER FOR THE CHIC-CHOCS RIDGES AND PEAKS

Thursday: Light intermittent snow. Wind from the southwest at 10 to 30 km/h. High −5°C.

Friday: Sunny. Wind from the west 10 to 30 km/h. High −12°C.

Saturday: Snow, 5 to 10 cm. Wind from the southwest 70 to 100 km/h. High -5. Freezing level at 300 m.

Terrain and Travel Advice

  • Recent wind has varied in direction, so watch for wind slabs on all aspects.
  • Pay attention to isolated wind affected features in the alpine, as well as cross-loaded features at treeline.
  • Carefully evaluate steep lines for wind slabs.

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.
