A Special Avalanche Advisory is in effect. Strong winds drifted new snow on an unusually shallow and very weak base. This makes for the greatest potential to trigger a large avalanche in wind-drifted terrain so far this season. They can break deeper into old snow layers on northerly and easterly-facing slopes. Also, keep an eye on steep sunny slopes. These could become wet and unstable as they warm throughout the day. Sticking to lower-angle terrain is the best way to stay safe.
Avalanche conditions will remain dangerous through the weekend. Careful planning and conservative terrain selection are essential for safe travel in backcountry avalanche terrain.
