Wind drifted snow yesterday was found to be more widespread than I anticipated and Dave observed sensitive, fresh deposits on all aspects at mid and upper elevations. Ranging in depth from 3"-12", wind slabs should be less sensitive today, but steep slopes with more than about 6" of freshly deposited snow should be carefully evaluated. Interspersed between areas of wind-scoured surfaces, recent drifts will be easily recognizable by their smooth, rounded appearance and cracking is a sign of instability.
Dave Garcia was able to crack out this wind slab on a SW aspect below treeline where swirling winds from a predominately SW direction still managed to deposit drifts of unstable snow.
