Isolated wind slabs may exist on Northerly-Easterly Aspects primarily in the Upper elevations and Near Tree Line. SW Winds yesterday were continuing to transport  snow and observations found a few isloated, shallow panels of snow that were reactive near tree line. Be on the lookout for potential wind slab development on slopes adjacent to ridgeline, deposition zones under cliff bands, and steeper convex terrain such as rollovers and cross loaded gully features. Stay focused on your exposure to down slope hazards, terrain traps, and the plethora of obstacles that exist where even a small slide could prove to be hazardous.
