Remember that even with a low danger rating, it is still possible to trigger an avalanche.
Although isolated, avalanche problems are still present and deserve to be assessed before committing to a challenging descent.

Snowpack Summary
5 to 10 cm of low density snow covers the various surfaces created by the extreme winds from the last weekend. In the alpine, at treeline and on open areas below treeline, these few centimetres overlies the January 18th crust, while in wind loaded areas, over 100 cm of compacted snow can be found on top of it.
Below the treeline, 35 to 45 cm of wind-pressed snow was found on top of the decomposing crust.In general, the height of the snowpack goes from 70 to 90 cm in the valley to 100 to 150 cm at mid-mountain.
Weather Summary
Forecast for the Chic-Chocs ridges and summits.
Synopsis: A ridge of high pressure will bring nice, but cold weather, on Thursday, followed by a low pressure that will leave several centimetres of snow on the Chic-Chocs.
Wednesday night and overnight: Mostly clear. Trace of snow. Winds from the northwest from 50 to 70 km/h. Min. -18C.
Thursday: Sunny, no precipitations. Winds from the northwest around 30 km/h with gusting up to 70 km/h. Max. -13C.
Friday: Cloudy. 10 to 15 cm of snow. Winds from the south around 50 km/h with gusting up to 80 km/h. Max. -8C.
Saturday: Cloudy. 3 to 5 cm of snow. Winds from the northwest from 45 to 50 km/h. Max. -20C.

Terrain and Travel Advice
- If triggered, wind slabs avalanches may step down to deeper layers resulting in larger avalanches.
- Avoid thin areas like rock outcroppings where you're most likely to trigger avalanches failing on deep weak layers.
Problems
Wind Slabs
Although there are moderate winds and small amounts of snow available for transport, meaning new wind slabs are building up, the problem lies primarily underneath the new snow, where the old wind slab overlie a layer of lower density.
Aspects: North, North East, East, South East, South.
Elevations: Alpine, Treeline.
Likelihood
Expected Size
Persistent Slabs
A layer with slab properties overlies a layer of facets over the January 18th crust. The likelihood of triggering an avalanche on this interface is unlikely, but the consequence of an event on this layer would be a large avalanche. Keep an eye out in areas where the snowpack is thinner.
Aspects: North, North East, East, South East.
Elevations: Treeline, Below Treeline.
