Loose dry avalanches up to size 2 in steep terrain continue to be reported in the region. Two wind slabs up to size 2 were observed at 1200m on southwest aspects on Saturday.
Winds have varied in direction over the past few days. Wind slab could be found on all aspects as a result.
Another surface hoar layer was buried recently , it is not a problem yet.
The December 18th surface hoar/facet layer is down 30cm, the surface hoar was observed up to 12mm in both the treeline and below . It is likely only a problem in isolated locations in the treeline where wind slab has formed above it.
The December 7 persistent weak layer is now typically down 100cm and has not produced avalanches in over a week.
Snowpack depths vary greatly across the region, expect to find anywhere from 100-300 cm of snow around treeline.
