Above 2500m, 60cm of snow from last week is being blown into soft windslabs in isolated areas. Below 2500m, up to 30 -50 cm of snow lies over the Nov 27th and Nov 23rd crusts. Both of these now overly the Halloween crust/ facet layer that sits 30-50cm above the ground. This lower layer presents as a facet layer above 2500m and as a crust below.

Natural avalanche activity has tapered, but concern remains for human triggering on the weak snow on this layer. Previously, slab avalanches have been triggered above ~ 2400m where the Nov. 23rd crust fades out. Shallow alpine areas warrant caution.
