Not much new to add to this other than the expected heavy snowfall and winds forecasted for the next few days are likely going to make these deeper weak layers reactive once again. Quite simply, no one should venture on or below slopes steeper than 30 degrees on aspects facing NW, N, NE, and E.

When I was out today I was focusing on weaknesses found on the old snow surface where a layer of surface hoar and near-surface facets had formed over the past few days. (Mark White has some nice photos of surface hoar development he observed on Tuesday in Broads Fork.) Whereas I was unable to find any preserved surface hoar in upper Big and Little Cottonwood, I did notice preserved near-surface facets underneath the small amounts of new storm snow. There wasn't enough of a slab on top to make this layer reactive, but with more snow and wind in the forecast, the new snow/old snow interface may be a reactive layer for avalanching.
