A persistent weak layer of faceted snow under the new snow from this week's snowfall (example photo below, the facets are the sugary looking snow under the new snow) can fracture and produce soft slab avalanches today. This layer exists mostly on northerly facing slopes but can be found on east facing slopes as well. Another observer in the Abajos yesterday got widespread collapsing on this layer on northerly facing slopes around 9000 feet on EVERY spot with a any amount of drifting. The snowpack is talking to us and saying its unstable. We should listen.
I wouldn't trust the snowpack and would be very conservative in my decision making on what slopes to cross and which ones to ride.
