    Fresh snow will not bond well to the old surface. Check for reactive slabs around steep and high-consequence slopes.

Snowpack Summary

A dusting of flurries has covered a crust on all aspects and elevations. Wind has redistributed loose snow into gullies and depressions with pocket wind slabs below steep, open features.

Multiple crusts exist in the upper snowpack. The mid and lower snowpack are well settled.

Terrain and Travel

  • Watch for wind-loaded pockets especially around ridgecrest and in extreme terrain.
  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.

Avalanche Summary

Rapid warming triggered several wet loose and wet slab avalanches to size 1.5 around the region Wednesday through Friday. The snowpack has since cooled and avalanche activity is unlikely, but re-frozen debris could be a real travel hazard.
