Regions

Chic-Choc Mountains.

The surface crust lowers the risk of triggering an avalanche but makes travel more difficult.

Watch out for small wind slabs that could form on top of this crust after the light snowfall that’s expected.

Confidence

Moderate

Avalanche Summary

No new avalanche observed or reported.

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

Snowpack Summary

In alpine areas and at the treeline, a breakable crust on the surface — present up to around 750 m — makes travel difficult. Beneath this layer, an ice crust lies 10 to 15 cm deep, just above a very firm surface formed during the mid-March thaw. This stacking of crusts complicates movement.

The middle of the snowpack consists of alternating well-settled snow and melt-freeze crusts.

At higher elevations, east- and southeast-facing slopes have better snow coverage, while north-facing aspects are more scoured. At mid-mountain, snow depth ranges from 60 to 180 cm.

Terrain and Travel Advice

  • Carefully evaluate steep lines for wind slabs.
  • Approach lee and cross-loaded slopes with caution.

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.
