Buried faceted snow. AKA: Persistent Weak Layer. This stuff remains a concern today and we'll be watching it for a while to come.
The weak layers down deep can still fail and produce a dangerous slab avalanche. The chance for this happening is decreasing every day by a little bit. 8 out of 10 slopes will probably not avalanche if someone gets on them. However, figuring out the remaining two slopes that will avalanche is not easy to do. A buried layer of facets is not a "manageable" situation. All you can do is avoid the steep northerly facing terrain until strength increases.
