Avalanche Summary

No new avalanches reported.

Snowpack Summary

Below freezing temperatures have developed a solid melt-freeze crust at all elevations and on most aspects. A couple of cm of new snow is now on top of the crust and/or facets and surface hoar that developed during the recent clear weather. A well settled mid and lower snowpack may rest on basal facets, especially in thin snowpack areas at higher elevations.

Confidence

Fair - Intensity of incoming weather systems is uncertain
