Stay warm and watch for wind slabs on steep open slopes.
Reactive wind slabs have been reported on a range of aspects, including lower elevations than usual. Expect the most reactive slabs in immediate lee terrain, such as just below ridgetops.
Natural wind slab avalanches (size 1 to 2) were observed on multiple aspects on Monday. Moderate to strong winds will continue to build wind slabs, with wind direction varying by elevation.
Strong, shifting winds have heavily affected alpine and treeline terrain, building wind slabs on many aspects and in some places extending into the trees.
Cold temperatures are faceting the surface, which may become an issue with new snow this weekend.
The snowpack remains generally deep and simple for the time of year, with treeline depths exceeding 300 cm.
