Rain and recent warm temperatures have significantly affected the snowpack at treeline and below. Small pockets of wind slabs may develop at upper elevations only.
Small pockets of wind slabs may develop on lee terrain features at upper elevations with upcoming precipitations. Avalanches may be particularly dangerous due to obstacles that are exposed or just below the surface.
No recent avalanches have been reported. Recent snow, rain, and wind may have caused isolated wind slabs and wet loose avalanches in steep terrain Thursday and Friday, but field observations are limited.
Up 15-20 cm of wet snow may be found at upper elevations, which has rapidly settled with warm temperatures on Friday. This recent snow is bonding well to the warm and moist snow beneath. The snowpack below 1500 m is either soaked with rain or slowly melting away. Total snow depths at ski hills and remote stations are 60 to 80 cm, with closer to 100 cm possible at treeline. Many areas are below the threshold depth for avalanches.
