Chic-Choc Mountains

Some snow in Thursday's forecast, but not enough to erase the effects of the crust.

Keep in mind that travel will remain difficult and that the crust can provide an excellent sliding surface for avalanches.

Forecast for the Chic-Chocs ridges and summits.

Wednesday evening and night: Snow, 2 to 5 cm. Wind northwest 50 to 70 km/h. Low -7.

Thursday: Snow, 2 to 5 cm. Wind northwest 30 to 50 km/h. High -10.

Friday: Alternating sun and clouds. Wind southeast 30 to 50 km/h. High -6.

Saturday: Sunny. Wind northwest 10 to 20 km/h. High -6

• Wind slabs are most reactive during their formation.
• Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
• Wind slabs may be poorly bonded to the underlying crust.

The deposit of a size 2 natural avalanche, possibly caused by a cornice fall, was observed by the field team at the base of the Frigo, in the very steep sectors of the mur des Patrouilleurs. This was 24 to 48 hours old.

By the end of the day on Thursday, 5 to 10 cm of new snow is expected in the mountains. This snow will be strongly displaced throughout the day by strong northwest winds. This snow will be deposited on a very firm icy crust in the alpine and on a more friable crust, which breaks under the weight of a skier, at and below the treeline. It goes without saying that travel in the alpine and on steep terrain will be perilous. The snowpack is still thin and the consequences of slipping on these icy surfaces could be fatal. Spatial variability is important, from rock to ice to areas of greater accumulation. Generally speaking, the thickness of the snow cover varies from 50 to 100 cm depending on the sector and the altitude.
