Snowpack Summary
Strong southerly wind and some new snow are likely forming new wind slabs in lee terrain features. Southerly slopes exposed to the wind are likely hard with a surface melt-freeze crust or wind-pressed snow.
There are no deeper layers of concern at this time. Thin snowpack areas may host various weak layers lower in the snowpack, which are likely dormant with the cool weather trend.
