Snowpack Summary

New snow on Wednesday will fall on about 50 cm of recent snow, which sits on a thick melt-freeze crust. Reports indicate that the snow is bonding well to the crust. Strong winds on Wednesday may redistribute snow, producing wind slabs in lee terrain features. Snow depths increase substantially with higher elevations. Expect to find about 200 cm at treeline elevations.
