Avalanche Summary

No new avalanches were observed on Monday. A few small avalanches were triggered by riders near White Pass over the weekend (see here and here).

We appreciate all your observations on the Mountain Information Network.

Snowpack Summary

Around 5 cm of snow and strong southerly wind are forecast, which will form new wind slabs in lee terrain features. In sheltered terrain, around 10 cm of softer snow may exist.

The remainder of the snowpack has been reported as being hard but heavily faceted.

Terrain and Travel

  • Wind slabs are most reactive during their formation.
  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
  • Avoid terrain traps such as gullies and cliffs where the consequence of any avalanche could be serious.
