Regions

Chic-Choc Mountains.

The danger rating will increase throughout the day as the storm moves in.

Confidence

Low

Avalanche Summary

No new avalanches reported or observed.

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

Snowpack Summary

A thin melt-freeze crust is present on the surface. The snow forecasted on Thursday will rest on this crust. Below this crust, a 15-30 cm layer of light snow covers a thick, solid melt-freeze crust dating from March 21.

At higher altitudes, the eastern and southeastern slopes enjoy better snow cover, while the southern, western and northern slopes are rather bare.

At mid-mountain, snow depth varies between 60 and 180 cm.

Weather Summary

Terrain and Travel Advice

  • Wind slabs are most reactive during their formation.
  • Closely monitor how the new snow is bonding to the crust.

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.
