Terrain and Travel Advice

  • Recent wind has varied in direction so watch for wind slabs on all aspects.
  • Extra caution for areas experiencing rapidly warming temperatures for the first time.
  • Back off if you encounter whumpfing, hollow sounds, or shooting cracks.
  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
