No new avalanches reported.

Snowpack Summary

5-10 cm of dry light new snow now covers the solid melt-freeze crust that developed last week. The new snow has been stripped by recent strong Northerly winds and transported into pockets of wind slab at higher elevations. Surface hoar was found in may areas before the new snow arrived, and cold temperatures are expected to preserve the surface hoar where it is buried below the thin layer of new snow. A well settled mid and lower snowpack may rest on basal facets, especially in thin snowpack areas at higher elevations.
