This problem will be with us all season. At higher elevations there is more concern that these deep persistent weak layers could be human triggerable.
Watch for pocket of deep persistent slabs in Alpine terrain along ridgelines and in steep crossloaded features.

Nothing new observed in the last couple of days.
There was a trace of a trace on Wednesday...
Strong winds have stripped all available snow and left hard slabs and scoured to ground where exposed. The early December rain crust is still present down about 30 cm but is starting to show signs of breaking down in valley bottom areas. Weak basal facets and depth hoar complete the lower snowpack. Overall conditions more closely resemble early November as opposed to Early January!
Daytime highs around -6C with moderate winds out of the SW. There will be a trace of new snow over the next 24hrs!
