    A new storm slab is expected to develop due to the forecast new snow and wind. The new snow is not expected to bond well to the old hard surfaces. There may also be a weak layer of surface hoar or facets sandwiched between the new snow and the crusts

Weather Forecast

Avalanche Summary

No new avalanches reported.

Snowpack Summary

Variable hard surfaces like wind slabs and sun crusts developed during the recent period with no precipitation. Some areas have a weak layer of surface hoar and/or surface facets that were on top of the hard sliding layers that are now buried. The new storm snow has not bonded well to these old surfaces, but reports suggest that the new snow has not consolidated into a cohesive slab. Forecast snow is expected to continue to develop a storm slab above the weak layers and sliding surfaces.
