Highlights

There are still isolated reports of settlements in thinner snowpack areas at higher elevations. It is still early winter, so although the chance of triggering a big avalanche has decreased, confidence is still not high in the big terrain. SH

    Previous wind slabs up to 30cm thick are still triggerable in steep, open terrain. 10-15cm expected this Saturday with light to moderate W winds will do little to change the overall hazard besides sloughing in steep terrain and near ridgetops.

    A well settled midpack overrides a weaker facetted base. This weak base is found most places except the west side of the divide. Beware of steep shallow snowpack areas (where the likelihood of triggering this basal layer is highest).
