Snowpack Summary
5 to 10cm of recent storm snow overlies the last pulse of settled snow from yesterdays storm. All of the recent storm snow is sitting on a variety of crusts on all aspects except perhaps north above 2000m. Once again, it appears that slightly more snow fell in the south of the region where they received 10 to 15 cm of snow. The storm featured moderate south/southwest winds that have most likely formed wind slabs on lee slopes around treeline and above. Below the new snow, the snowpack is generally well-settled throughout with no notable persistent weaknesses, however, cornices are are reported to be huge and fragile. Be aware that as the high pressure comes into the region the winds will shift and be from the north. This could lead to reverse wind loading and build wind slabs on the south aspects below ridge tops.
