    Snow and wind loading with gusting winds created a wind slab hazard. The team has limited snowpack observations yet tests show the base is weak and the new snow interface is uncertain. Remain vigilant for reactive and changing conditions.

Terrain and Travel Advice

  • Avoid freshly wind loaded terrain features.
  • Be aware of the potential for loose avalanches in steep terrain where snow hasn't formed a slab.
