Snowpack Summary

Up to 25 cm of new snow accompanied by moderate to strong southwesterly winds is expected by Saturday evening. This falls over 80 cm of rapidly settling snow from recent storms. Under the storm snow, sits a mid December crust. The lowest snowpack layers are generally a series of melt forms to the ground, with the exception of above 1700m where the mid-November crust/facet layer can still be found in select areas.
