Snowpack Summary
In leeward areas, between 3 and 5 cm of very light new snow rested directly on the crust formed by the rain and ice from Saturday night. The southern aspects, exposed to the wind, are swept down to the crust or the rock. The surface crust supports the weight of a skier in the alpine and at the treeline.In areas of significant accumulation, between 5 and 15 cm of snow can be found between this surface crust and that of December 1, 2022. At the beginning of the season, the height of the snowpack varies from 25 to 55 cm in general and up to 70 to 80 cm in areas of maximum accumulation. Conditions remain marginal, with barely enough snow to cover obstacles and a crust (or two...) that makes travel difficult and hazardous.Rain, warm temperatures and southerly wind expected on Wednesday will not improve these conditions ...

Terrain and Travel Advice
- Carefully evaluate steep lines for wind slabs.
- Wind slabs may be poorly bonded to the underlying crust.
Problems
Wind Slabs
Wind slabs can be found on leeward aspects, mainly in gullies, depressions and terrain breaks. The strong wind of the last few days, as well as the early season conditions, make this problem very sporadic and isolated, so it does not affect the hazard index. Consider recently loaded areas in the alpine as having a higher hazard rating.
Aspects: North, North East, North West.
