The weak Oct.26 facets and depth hoar at the base of the snowpack have a significant slab (50-130cm thick) sitting above them. The likelihood of triggering this layer has decreased, but if it does get triggered, the avalanche will be large in size.
Thin wind slabs are stubborn but still show potential for triggering in the alpine. Increased winds on Thursday may add to their development. These will not be a long term problem.
Deep persistent slabs are best managed by:
Cornices are best managed by:
Continued mild temperatures for January with highs in the -2 to -4C range at valley bottom and -8 to -10C at 3000m with West winds increasing to strong in the alpine. Only a few cm of snow is expected over the next 2 days.
10-20cm of snow over the last few days. Thin wind slabs can be found in alpine lee areas from strong SW winds on Saturday. Of greatest concern are the weak facets and depth hoar at the base of the snowpack. In thinner snowpack areas with less than 150 cm of snow, triggering a slab on these facets is more likely.
No new avalanches reported or observed.
