Uncertainty about a buried weak layer warrants conservative terrain choices.
The early December weak layer may still be triggered in shallow, thin-to-thick areas, or with large loads like a cornice or avalanche.
No new avalanches were reported Wednesday or Tuesday (at time of publishing). On Monday, a few size 1 to 2 natural avalanches occurred on northeast alpine slopes.
There have been no recent reports of persistent slab avalanches, but uncertainty remains. Snowpack test results and whumpfing suggest it may still be triggerable in some areas.
10 to 20 cm of new snow fell on Monday and Tuesday. Expect lesser amounts of new snow the further east you go. It came with strong southwest wind which built slabs on lee slopes and scoured exposed areas back to old, hard layers.
A weak layer of facets and a crust from early December is buried 50 to 100 cm deep. This layer exists on all aspects up to around 1700 m.
