Regions

Chic-Choc Mountains.

Take the time to assess how the new snow adheres 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

Between 10 and 15 cm of new snow covers 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

Thursday evening and night: Snow. Snow accumulation of 5 cm. Risk of freezing rain overnight. Westerly winds of 30-40 km/h becoming light overnight. Temperatures rising to -2 overnight.

Friday: Snow. Accumulation of 2 cm. Wind northwest, 15 to 30 km/h. Maximum -2. Freezing level at 500 m.

Saturday: Alternating sun and clouds. Light southerly winds. High -2. Freezing level at 700 m.

Sunday: Snow. Accumulation of 10 cm. Southwest winds, 25 to 40 km/h. Maximum 0. Freezing level at 700 m.

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.
