A strong and supportable snow surface refreeze is expected to have occurred last night with near to below freezing air temperatures aided by radiational cooling under clear skies. As daytime warming progresses, areas of surface wet snow will form on sun exposed slopes. With the snowpack already subject to periods of rain and prolonged melt earlier this winter, free water drainage from the snowpack is well established. With little to no snow cover on the vast majority of SE-S-SW-W aspects, minimal instability concerns are expected on those aspects. E aspects continue to hold significant snow cover around the vast majority of the forecast area and will experience surface wet snow formation up to several inches deep by this afternoon. With free water drainage well established, wet snow instability is expected to be limited to human triggered roller balls and human triggered loose wet sluffs that require a push to set into motion in steep terrain. Loose wet avalanches large enough to bury or injure a person are unlikely today.
