Avalanche Problems
Wind Slabs
New, reactive wind slabs will likely be found in exposed terrain. Due to the potential for variable wind, wind slabs may be found on all aspects. These new slabs may not bond well to the hard surfaces they are forming over.
Aspects: All aspects.
Elevations: Alpine, Treeline.
Likelihood: Likely
Expected Size: 1 - 1.5
