The rain on Saturday will not improve the conditions in the mountains at all.

Avalanche Summary
No new avalanche activity has been observed or reported. Please share your observations at info@avalanchequebec.ca, or with the Mountain Information Network.
Snowpack Summary
About 5 to 10 cm of new snow covers the widespread melt-freeze crust 1 to 4 cm thick present at all aspects and elevations. Isolated pockets in localized leeward depressions can reach 15 to 20 cm in places.
At the start of the season, the height of the snowpack varies from 30 to 50 cm in general and up to 70 to 80 cm in the areas of maximum accumulation. The conditions remain marginal, with barely enough snow to cover the obstacles and a crust that makes travel difficult and perilous.

- Wind slabs may be poorly bonded to the underlying crust.
- Be carefull around freshly wind loaded features.
Problems
Wind Slabs
Small isolated wind slabs are possible at the top of eastern lee slopes, in depressions and gullies and in cross loading areas. These cover a crust which could potentially form an excellent sliding surface.
Aspects: North East, East, South East.
Elevations: Alpine.
