Forecast snow may form small wind slabs on lee features below alpine ridgetops.

Avoid steep, rocky, and wind effected areas where triggering slabs is more likely.

Summary

Confidence

Moderate

Avalanche Summary

A couple of naturally triggered wet slab avalanches up to size 2 were reported on sunny aspects on Tuesday.

Snowpack Summary

5 to 15 cm of forecast snow may form small wind slabs on lee features below alpine ridgetops. The new snow overlies a crust on all aspects and elevations.

A widespread crust with facets above is down 60 to 110 cm. This layer is unlikely to human trigger in areas where a thick crust above the weak layer is present.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
  • Avoid steep, rocky, and wind effected areas where triggering slabs is more likely.
  • When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
