Weather Forecast

west.

Avalanche Summary

No new avalanches were observed.

Snowpack Summary

Wind slabs are mostly noticeable in cross loaded and lee features in the alpine. Sheltered areas at all elevations are still providing good skiing. Overall the midpack feels well settled and solid at treeline and below. The buried wind slabs in the top 50cm in the alpine are still on our radar; it is worth to dig and see how they are reacting. Last week's rain crust is down about 20cm and is easy to find below 1950m. 

Terrain and Travel

  • Approach lee and cross-loaded slopes with caution.
  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
