Avalanche Summary

Snowpack Summary

The winter snowpack is mostly gone from lower elevations. On northerly facing slopes and on glaciated terrain snow can still be found and may present or conceal hazards. On warm days the snow will be soft and unstable making travel difficult and potentially dangerous. Cool clear nights might cause the snow to freeze into a hard slippery surface.
