Moderate

Avalanche Summary

We haven't received reports of recent avalanches. Looking forward, isolated pockets of wind slabs could be triggered by riders in steep lee terrain features.

Snowpack Summary

5 to 10 cm of soft snow from the weekend overlies a settled snowpack. Southerly wind may have formed pockets of wind slabs in lee terrain features.

Snow depths at White Pass are around 100 cm in sheltered areas and 200 cm on wind-loaded slopes.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
  • Use ridges or ribs to avoid areas of wind loaded snow.
  • The best and safest riding will be on slopes that have soft snow without any slab properties.
