Snowpack Summary

Only trace amounts of snow below 1700m. Above 2000m, a generally strong, and supportive early winter snowpack exists with depths ranging from 30 to 100+ cm depending on aspect and exposure to wind. Wind effect to the recent snow has loaded northerly exposed slopes and ridge tops in the alpine, expect this to continue.
