Snowpack Summary

Tuesday and Wednesday saw very heavy amounts of precipitation. The freezing level hovered around tree line during that time, however it can be expected that 70-100cm of snow fell at upper elevations. The new snow would have been redistributed by moderate to strong southwest wind and is sitting on a well settled lower snowpack. Rain below tree line has soaked an already moist and/or wet lower snowpack.
