Regions

Chic-Choc Mountains.

Snow for the Chic-Chocs! There could be a good variability in the amount of snow received across our forecast area.

If you find yourself in a location with more precipitation than expected, take advantage of it! But remember, it's still early season!

Snowpack Summary

On Monday morning, we could already find 5 to 10 cm of new snow on the Chic-Chocs. The snow should continue to accumulate throughout the day until Tuesday morning. The easternmost sectors of our forecast area are likely to see the heaviest accumulations.On the lee aspects, this new snow will cover the 15 to 30 cm already accumulated on the December 8 crust. In some areas where the loading was heavier, up to 100 cm of snow accumulated on this crust. The strong to extreme northeasterly winds of the last few weather systems have already greatly redistributed the snow, exposing the rock or crust on the windward slopes and this trend will continue with this new depression.Despite the fresh snow, snow conditions will remain minimal. Remember that crust and obstacles such as rocks, stumps, trees and trunks can still be found barely buried under this beautiful white carpet.

Weather Summary

Forecast for the Chic-Chocs ridges and summits.

A low-pressure system will remain quasi-stationary over the Maritimes and will bring snow to the Chic-Chocs from Sunday evening until Tuesday. Areas northeast of Highway 299 will be favoured by precipitation. The coastline could see a few episodes of mixed precipitation. Sunday night and overnight: Snow, 5 to 10 cm. Wind northeast, 40 to 70 km/h. High -3. Freezing level at 200 m.Monday: Snow, 10 to 15 cm. Wind northeast, 50 to 70 km/h. High -3. Freezing level at 250 m. Tuesday: Intermittent snow, 2 to 3 cm. Wind northeast, 20 to 40 km/h. High -4Wednesday: Cloudy. Wind south 10-20 km/h. High -5.

Terrain and Travel Advice

  • Wind slabs are most reactive during their formation.
  • Wind slabs may be poorly bonded to the underlying 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.
