Regions

Chic-Choc Mountains, Littoral, Murdochville.

The new snow will rest on a wind slab interface that has proven to be very unstable over the last few days.

Avoid the alpine and open areas, and aim for objectives below treeline, where the snow will be less affected by the strong winds.

Confidence

Low

Avalanche Summary

A new size 2 slab avalanche was accidentally triggered by a group of skiers at the top of the Mur des Patrouilleurs of Mont Albert on sunday afternoon. 2 persons have been involved, but ended up at the top of the debris, without any injuries.

Snowpack Summary

Near the summits, the wind has redistributed the available snow, exposing the crust or ice at the surface and creating an overlay of slabs of variable density. Cornices are building up in the alpine with the winds from the past couple days. In sheltered areas, the February 17th crust is found under 15 to 30 cm of low density snow. Facetted grains are slowly developing on this crust. The mid-snowpack is well consolidated, with the January 18th crust down 40 to 70 cm below the surface. The base of the snowpack consist of laminated crust and basal facets.

In general, the height of the snow cover varies from 70 to 90 cm in the valley to 100 to 150 cm in the middle mountains.

Weather Summary

Forecast for the Chic-Chocs ridges and summits.

Synopsis: The Chic-Chocs will be under the influence of a major low system that will bring uncertain amounts of snow over the next two days.

Sunday night and overnight: Cloudy. 5 to 10 cm of snow. Winds from 60 to 70 km/h from the north. Min. -12C.

Monday: Cloudy. 5 to 15 cm of snow. Winds from 55 to 65 km/h from the northeast. Max. -10C.

Tuesday: Cloudy. 3 to 5 cm of snow. Winds from 35 to 50 km/h from the northeast. Max. -6C.

Wednesday: Cloudy. Trace of snow. Winds from 50 to 60 km/h from the northeast. Max. -10C.

Terrain and Travel Advice

  • Be careful to keep storm day fever from luring you out into bigger terrain features.
  • Storm slabs in motion may step down to deeper layers resulting in large avalanches.
  • As the storm slab problem gets trickier, the easy solution is to choose more conservative terrain.

Problems

Storm Slabs

Storm Slab avalanches are the release of a cohesive layer (a slab) of new snow that breaks within new snow or on the old snow surface. Storm-slabs typically last between a few hours and few days (following snowfall). Storm-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.
