Avalanche Summary
Natural avalanches up to size 2.0 and ridder triggered up to 1.5 have been observed.
Snowpack Summary
Up to 15cm of new snow fell in the most recent storm pulse. This adds to the previous storm snow, with 45 cm being an average amount over the mid February layers. These layers are a strong melt freeze crust at lower elevations and wind effected snow higher in the alpine while between these elevations, the interface varies wildly from facets, surface hoar, sun crust or wind press. The surface hoar is not widespread but is responsible for much of the recent avalanche activity. With the additional wind loading, pockets as deep as 60cm are possible on lee features.
