Regions

Chic-Choc Mountains.

The spatial variability of snowpack is considerable in the forecast area. Localized risk assessment is essential.

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

At treeline and in the alpine, surface snow is strongly affected by wind, resulting in great variability in its distribution and density. There is considerably more snow in the northern part of the forecast area (Mines versus Lyall).

The average snow depth at treeline varies between 90 and 120 cm. The cold weather of the past week has promoted the faceting process within the snowpack.

Weather Summary

WEATHER FOR THE CHIC-CHOCS RIDGES AND SUMMITS

A weak low pressure system brings milder temperatures on Sunday, before dropping off early in the week.

Saturday evening and night: Partly cloudy. No precipitation. Southwest winds from 25 to 35 km/h. -16C.

Sunday: Increasing clouds. Light snow beginning in the afternoon. Wind from the southwest from 35 to 45 km/h. -16C.

Monday: Cloudy. Light snow. Wind from the southwest from 45to 55 km/h. -20C.

Tuesday: Cloudy. 10 to 15 cm of snow, ending in the morning. Northwest winds from 45 to 55 km/h. -23C.

Terrain and Travel Advice

  • Watch for areas of hard wind slab on alpine features.
  • Wind slabs are isolated, but may remain reactive.
  • Be cautious of buried obstacles, especially below treeline.

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.
