Regions

Chic-Choc Mountains, Chic-Chocs.

A melt-freeze crust near the surface makes travel more difficult and can lead to an uncontrolled fall. The use of ski crampons is recommended; make sure to install them at the base of slopes to avoid getting into a hazardous situation.

Confidence

High

  • We have a good understanding of the snowpack structure and confidence in the weather forecast.

Avalanche Summary

No new avalanches have been observed or reported.

If you head into the backcountry, thanks for sharing your observations on the Mountain Information Network (MIN).

Snowpack Summary

Overnight from Sunday to Monday, up to 10 cm of snow fell at higher elevations and was redistributed by the wind. This snow rests on a new melt-freeze crust 3 to 5 cm thick. Below this crust, the snowpack is moist and becomes fully isothermal at lower elevations. On north to east aspects, a melt-freeze crust formed in mid-March is still present at a depth of 10 to 50 cm.

At mid-elevations, the average snowpack depth is approximately 125 cm.

Weather Summary

WEATHER FOR THE CHIC-CHOCS RIDGES AND PEAKS

A high-pressure system is settling over the Gaspé Peninsula for the next few days, bringing fair weather and light winds.

Monday evening and night: Partly cloudy. Northwest winds at 20 to 40 km/h. Low of -10 °C. Freezing level in the valley.

Tuesday: A mix of sun and cloud. West winds up to 15 km/h. High of -5 °C. Freezing level at 300 m.

Wednesday: Sunny. Northwest winds up to 15 km/h. High of 2 °C. Freezing level at 750 m.

Thursday: A mix of sun and cloud. Light north winds in the morning, increasing to moderate in the afternoon. High of 2 °C. Freezing level at 625 m.

Terrain and Travel Advice

  • Although avalanches are unlikely when a hard crust exists on the snow surface, the crust may pose a slip and fall hazard.
  • Carefully evaluate steep lines for wind slabs.
  • Pay attention to cornices and give them a wide berth when traveling on or below ridges.

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.
