Fresh, reactive wind slabs are expected to form at upper elevations with strong winds.
As rain will be turning into snow, total snowfall amounts are uncertain.
Fresh, reactive wind slabs are expected on northerly aspects at upper elevations, with new snow and strong southwest winds. Be cautious around ridge crests and in steep terrain, where human triggering is most likely.
Evidence of a small loose avalanche from the past weekend may still be visible. The likelihood of avalanches will increase with ongoing strong winds and rain turning into snow on Tuesday night.
At lower elevations, rain has created a moist snow surface. At higher elevations, new snow accumulates on a crust or moist snow except high north-facing alpine where the snow surface may remain dry.
