Confidence

Moderate

Avalanche Summary

Recent avalanche observations are limited to a few small dry loose avalanches.

Snowpack Summary

Recent strong southerly wind formed wind slabs in lee terrain features near ridges. Terrain sheltered from the wind has about 10 cm of soft snow. This snow may sit above a layer of surface hoar crystals. A weak layer of facets that formed during the arctic outbreak in December is buried 30 to 60 cm deep. Observations suggest it is fairly widespread, but not reactive to triggering under the current conditions.
