Regions

Chic-Choc Mountains.

Natural avalanches are becoming increasingly unlikely, but those triggered by a skier are still possible.

Exercise caution when approaching wind-loaded slopes or those recently loaded by the wind.

Confidence

High

Avalanche Summary

No new avalanches were observed or reported.

If you are out in the backcountry, please share your observations on the Mountain Information Network (MIN).

Snowpack Summary

In wind-protected areas at and below the tree line, up to 40 cm of light snow is found resting on a thin, friable crust.

The wind has altered the snow cover in the alpine, creating significant variability: some areas are bare, others are compacted or eroded, while some have accumulated snow. The east and southeast slopes have been favored by recent loading. A thin crust is buried beneath the new snow on the sunny slopes of the alpine up to about 700 m.

The middle of the snowpack is well consolidated, resting on a layer of faceted grains that are rounding out.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Be careful with wind-loaded pockets, especially near ridge crests and rollovers.
  • Avoid steep, rocky, and wind-affected areas where triggering slabs is more likely.

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.
