Snowpack Summary

Strong East-Northeast winds overnight may have transported any loose snow that was left on North aspects. Below freezing temperatures have developed a solid melt-freeze crust at all elevations and on most aspects. A couple of cm of new snow is now on top of the crust and/or facets and surface hoar that developed during the recent clear weather. A well settled mid and lower snowpack may rest on basal facets, especially in thin snowpack areas at higher elevations.
