Avalanche Summary
No new avalanches reported.
Snowpack Summary
5-10 cm of light dry snow now sits above a solid melt-freeze crust at all elevations and all but some very sheltered North aspects. There was a widespread surface hoar layer reported after the temperature inversion ended. I suspect that the thin layer of light dry snow has buried the surface hoar, but at this time there is not enough snow above this weak layer to create an avalanche danger. The deep persistent layer of weak facets continues to be a concern in shallow snowpack areas, however the re-frozen upper snowpack may make triggering less likely.
