Snowpack Summary

Around 20 cm of recent snow fell above 1500 m. Another 10 cm of snow is expected on Sunday above 1700 m, with associated strong to extreme southwest wind. This will likely form new wind slabs. All this recent snow overlies a melt-freeze crust or wet snow. Below 1500 m, the snowpack is wet and rapidly melting.
