Primary Problem: Persistent Slab
Bottom Line: Twenty to 40 mph winds are transporting 12-20” of snow since Friday into cohesive slabs and making human-triggered avalanches likely. Weak layers formed at the surface during last week’s high pressure are the primary culprit. Avoid wind-loaded slopes. Dig below the recent snow to evaluate for instability at the interface of the older snow and snow that fell since Friday before considering travel on non-wind-loaded terrain steeper than 30 degrees. Shooting cracks, collapsing and recent avalanche activity supersede any indicator of stability.
