Regions

Chic-Choc Mountains, Chic-Chocs.

It is still possible for a skier to trigger a wind slab avalanche on slopes that have recently been loaded by the wind. As these slabs rest on a crust, their stability remains uncertain. Assess wind-loaded slopes carefully before venturing onto them and give preference to those that have not been affected.

Confidence

Moderate

  • We are uncertain due to the variability of wind effect on the snowpack.

Avalanche Summary

Some signs of instability were observed on the eastern slope of Hog's Back on Saturday, as reported on the Mountain Information Network: https://avalanche.ca/mountain-information-network/submissions/2037f855-1fea-11f1-b0a6-0a58a9feac02

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

Snowpack Summary

Since Wednesday, between 20 and 30 cm of fresh snow has fallen. A thin layer of ice pellets lies within this snow, approximately 10 to 15 cm below the surface. That new snow rests on a widespread melt-freeze crust in the mountains. This crust generally supports a skier’s weight in alpine terrain, but it is less supportive below the tree line.

We will be monitoring these two more fragile layers closely (crust and ice pellets), as they could persist within the snowpack and slow down the stabilisation of the slabs covering them.

Beneath this widespread crust, the middle of the snowpack remains well consolidated.

Strong to extreme winds from the south, then from the north-west, have created significant variability in the snowpack in alpine terrain and at the tree line, and in places even below the tree line.

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

Weather Summary

WEATHER FOR THE CHIC-CHOCS RIDGES AND PEAKS

A high-pressure system will bring us a brief spell of clear weather on Sunday afternoon, before we come under the influence of a strong low-pressure system bringing warm temperatures, rain and wind at the start of the week.

Saturday evening and night

Intermittent snow, 1 to 2 cm. Light wind veering north-westerly. High -12°C.

Sunday

Light, intermittent snow clearing in the morning. North-westerly wind 20–40 km/h. High -8°C.

Monday

Snow, 2–4 cm. South-easterly wind 50–80 km/h. High -2°C. Freezing level at 450 m.

Tuesday

Rain, 15 to 30 mm. Southerly wind 30 to 90 km/h. Maximum +8°C. Freezing level at 3300 m.

Terrain and Travel Advice

  • Approach lee and cross-loaded slopes with caution.
  • Keep in mind a buried crust offers an excellent bed surface for avalanches.
  • The best and safest riding will be on slopes that have soft snow without any slab properties.
  • 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.
