Snowpack Observations
An additional 30-35cms of new light (F-F+) snow sits atop the additional storm snow from the previous days. Now in most locations, there is anything from 40-60cms of new storm snow sitting atop the most recent rain crust (11/25 rain crust). The snowpack overall is still quite shallow, with total HS ranging from 50-80cms at this location.
