Regions

Chic-Choc Mountains.

Light snow dusts a solid melt-freeze crust, creating challenging travel conditions.

Enjoy another winter-like day in the mountains with (rare) light wind.

Avalanche Summary

No new avalanche was reported or observed on Tuesday.

On Monday, a wind slab avalanche (size 1.5) was observed in the Bol de Toilette, at Grande-Cuve, Mont Albert. It was naturally triggered over the weekend and slid on the March 21 crust.

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

Snowpack Summary

On leeward slopes, 10 to 15 cm of new snow sits atop a solid melt-freeze crust formed on March 21st.

In the alpine and at treeline, this new snow overlies various surfaces such as a crust, wind-affected pockets, or bare ground. In areas of maximum loading on east and southeast slopes, isolated spots can be found where accumulations may reach up to 30 cm.

At mid-mountain, the snowpack height ranges from 60 to 150 cm.

Weather Summary

WEATHER FOR THE PEAKS AND SUMMITS OF THE CHIC-CHOCS

A lingering trough will provide cloudy skies, flurries, and rising temperatures for Wednesday.

Tuesday evening and night: Cloudy. Isolated flurries up to 2 cm of new snow. 20 km/h south wind. Minimum -6 C.

Wednesday: Cloudy. Isolated flurries with 3 to 5 cm of new snow. 10 to 20 km/h southwest wind. Maximum 0 °C. Freezing level around 500 m.

Thursday: Cloudy. 20 km/h northwest wind. Maximum -5 C.

Friday: Cloudy. Snow beginning in the afternoon with 5 to 10 cm of new snow. 20 to 40 km/h northwest wind. Maximum -4 C.

For more details, read the Chic-Chocs alpine weather forecast.

Terrain and Travel Advice

  • Carefully evaluate steep lines for wind slabs.
  • Closely monitor how the new snow is bonding to the crust.
  • Avalanche activity is unlikely when a thick melt-freeze crust is present on the snow surface.

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.
