One large avalanche was observed on Sunday, which was suspected to have been a reloaded bed surface and possibly failing on the sugary faceted grains and sun crust described in the snowpack summary. Otherwise, no new avalanches were observed in the region.

Wind slabs are reported as being widespread at treeline and alpine elevations. These formed from the recent storm that deposed 50 to 90 cm of snow with strong southwest winds. There have been reports that all this snow is not bonding well to underlying surfaces in areas. Below treeline, this new snow is likely settling and gaining strength.There are a few deeper weaknesses in the snowpack. Professionals are still tracking a layer around 150 to 200 cm deep, composed of sugary faceted grains, feathery surface hoar, and a sun crust. The base of the snowpack may also still be composed of weak faceted grains in parts of the region. The likelihood of triggering these deep weak layers is low and would most likely be triggered by humans in areas where the snowpack is shallow.
