Snowpack Summary
Up to 15 cm of new snow fell over the South Coast region over Thursday night, with average new snow amounts closer to 5 cm. In some areas, the new snow overlies up to 3cm of recent graupel accumulation. Below the new snow and graupel, the previous snow surface is a mix of sun crust on solar aspects and surface hoar on shaded aspects. The new snow's bond to these surfaces will take some time to form. Older storm snow can be found below the new snow interface and it is reportedly well bonded to the widespread mid-February rain crust, now found down around 40-60 cm at higher elevations. The crust itself is supportive and roughly 20cm thick. Below the crust, the snowpack is still moist as a result of heavy rain from last week.
