Generally safe avalanche conditions. Evaluate steep lines for pockets of wind slab, even small avalanches can have serious consequences in extreme terrain.

Confidence

Moderate

Avalanche Summary

A few isolated, small (size 1) wind slabs were triggered by riders on Monday. Otherwise, no new avalanches were observed.

Snowpack Summary

Widespread crusty surfaces exist on all but high north-facing alpine terrain, where snow is dry and likely wind affected. There are no deeper concerns at this time.

Terrain and Travel Advice

  • Carefully evaluate steep lines for wind slabs.
  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
