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.
