Highlights

Only simple terrain with no exposure to overhead hazard is suitable for the current conditions. 

Storm slabs have the potential to step down and trigger large, destructive avalanches.

Terrain and Travel Advice

  • Avoid exposure to overhead avalanche terrain; avalanches may run surprisingly far.
  • Storm slabs in motion may step down to deeper layers resulting in large avalanches.
  • Keep your guard up at lower elevations. Storms slabs have been reactive at all elevations.
