Monday morning, December 9, 2019
The overall avalanche danger is MODERATE. The danger is most pronounced in the highest terrain which received the most snow and most wind. Watch for fresh drifts along the upper east facing ridges. By far the biggest concern is on slopes approaching 40 degrees above about 9000 feet that face northwest, north, and northeast where an avalanche could break into old weak sugar snow near the ground.

Description
The new snow from Sunday will most likely make things slightly more sensitive on the high northerly facing steep slopes where the old weak sugar snow from October is present. Continue to avoid slopes steeper than about 30 degrees on those slopes if you want to stay safe.
