Snowpack Summary

Variable hard surfaces that developed during the recent dry spell have been buried by 10-15 cms of new snow. A weak layer of surface hoar or near surface facets was reported on the surface before being buried. Incremental snow falls are expected to continue to build a new storm slab above these weak layers and sliding surfaces.
