Regions

Chic-Choc Mountains, Chic-Chocs.

Test the reactivity of the new snow as you move through the mountains.

Confidence

Moderate

  • Forecast snowfall amounts are uncertain.

Avalanche Summary

No avalanche activity was observed or reported.

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

Snowpack Summary

Between 20 and 30 cm of new snow is forecast between now and Tuesday evening. The melt-freeze crust from December 20 will then be 30 to 50 cm deep. Snow cover is very unevenly distributed in the mountains due to recent wind events. There is considerable spatial variability, ranging from bare rocky slopes to wind-blown snow accumulations.

Conditions remain typical for the beginning of the season: there are numerous obstacles on the ground.

Weather Summary

A winter storm will hit the Gaspé Peninsula on Monday evening and bring 20 to 30 cm of snow by Tuesday evening.

WEATHER FOR THE CHIC-CHOCS RIDGES AND PEAKS

Monday evening and night: Snow, at times heavy. Accumulation of 15 to 25 cm. Wind from the southeast at 60 to 100 km/h. Low of -4.

Tuesday: Snow. Accumulation of 5 to 10 cm. Wind from the southwest at 20 to 40 km/h. High of -2.

Wednesday: Alternating sun and clouds. Wind from the southwest at 20 to 30 km/h. High -18.

Thursday: Intermittent snow. Accumulation of 4 to 6 cm. Wind from the south at 30 to 50 km/h. High -10.

Terrain and Travel Advice

  • Wind slabs are most reactive during their formation.
  • Be cautious of buried obstacles, especially below treeline.

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.
