The alpine rating is Storm Slabs.
, the treeline rating is , and the below treeline rating is Known problems includeThe winds associated with the last storm have created a great spatial variability in the snowpack. Isolated instabilities may persist.
Watch for signs of instability such as whumphing or shooting cracks.

Avalanche Summary
No new avalanche was reported or observed. If you go into the backcountry, thanks for sharing your observations at bulletin@avalanchequebec.ca or on the Mountain Information Network (MIN).
Snowpack Summary
The extreme winds from the last storm have redistributed the snow very unevenly. The eastern and southern aspects are generally exposed to the crust. On the lees aspects (North west to North East), wind-pressed pockets of dense snow are showing impressive accumulations, with up to 130 cm of snow overlying the New Year's crust. A layer of facets has been observed between this new snow and the crust. Below treeline, despite this latest storm, the hazard is generally below threshold.

Terrain and Travel Advice
- Continue to make conservative terrain choices while the storm snow settles and stabilizes.
- Wind slabs may be poorly bonded to the underlying crust.
- Watch for areas of hard wind slab on alpine features.
Problems
