Several small wind slabs were triggered by people on Monday on north to north-east aspects near treeline. On Sunday, several explosives-triggered avalanches to size 2 were reported in the region at or near treeline on all aspects.

Recent snow and winds have created variable storm slabs and wind slabs. Wind slabs were observed at all elevations on Monday. Isolated layers of surface hoar and or crusts may be found in the upper snowpack. Around 1 m down in the snowpack is a buried weak layer that formed in early December. It consists of a rain crust, surface hoar, and facets (sugary snow). Professionals continue to monitor this interface as it has potential to produce large avalanches, although the likelihood of triggering has gone down. It is most likely to be triggered from a thin-spot trigger point or with a large load, like cornice fall.
