Southwest through northwest winds have formed thin wind slabs over a crust / surface hoar layer and may propagate farther than expected. Dig down and investigate the bond of new snow before committing to your line.
Avoid open slopes and convex rolls at and below treeline where buried surface hoar may be preserved.
Aspects: North, North East, East, South East, South, South West.
Elevations: Alpine, Treeline.
LikelihoodLikely - Possible
Expected Size1 - 2
Deep Persistent Slabs
This layer likely requires a large trigger. Be cautious when transitioning from thick to thin snowpack areas
Avoid steep convexities or areas with a thin or variable snowpack.
Aspects: All aspects.
Elevations: All elevations.
