Be alert to conditions that change throughout the day with rising temperatures.
Avalanches are possible on slopes with wet or wind-affected snow.
New snowfalls and strong wind have formed reactive slabs on lee terrain features at upper elevations. Be alert to conditions that change with elevation and wind exposure.
Rain and rising temperatures could destabilize surface snow at treeline elevations and produce small wet, loose avalanches. 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 since Thursday but field observations are limited.
Up to 30-40 mm of precipitation has fallen since Wednesday night, with rain below 1500 m. Up 15-20 cm of wet snow may be found at upper elevations. This new snow should bond well to the warm and moist snow beneath. 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.
