Regions

Chic-Choc Mountains.

Saturday promises to be a beautiful day in the mountains, but take the time to check how the wind slabs are adhering to the underlying crust.

Confidence

Moderate

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

The snowpack in the alpine and at treeline is highly variable. Conditions vary from a frozen surface, or even hard ice, to an accumulation of wind-blown snow.

Below treeline, we find 10 to 15 cm of fresh snow resting on a thin melt-freeze crust. Beneath this crust, a 15-30 cm layer of light snow covers another thick, solid melt-freeze crust dating from March 21. The middle of the snowpack is made up of a superposition of well-consolidated snow and melt-freeze crusts.

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

WEATHER FOR THE PEAKS AND SUMMITS OF THE CHIC-CHOCS

Saturday promises to be a beautiful day in the mountains.

Friday evening and night: A few flurries, ending around midnight. Snow accumulation of 2 to 4 cm. Northwest winds, 20 to 30 km/h. Low -7.

Saturday: Sunny, cloudy in the afternoon. Wind south, 10 to 20 km/h. High -2. Freezing level at 600 m.

Sunday: Snow. Accumulation 10 to 15 cm. Possibility of rain in the afternoon. Southwest winds, 30 to 60 km/h. Maximum +2. Freezing level at 700 m.

Monday: Sunny. Wind west, 20 to 40 km/h. High -5.

Terrain and Travel Advice

  • Closely monitor how the new snow is bonding to the crust.
  • Be alert to conditions that change with elevation, aspect, and exposure to wind.
  • Keep in mind a buried crust offers an excellent bed surface for avalanches.

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.
