Avalanche Summary

No new avalanches have been reported.

Snowpack Summary

Small amounts of dry snow accumulate over crusts and moist snow.

The mid and lower snowpack is generally uniform, with no significant layers of concern.

Below treeline, most areas are below threshold for avalanches.

Terrain and Travel Advice

  • Storm snow and wind is forming touchy slabs. Use caution in lee areas in the alpine and treeline.
  • Closely monitor how the new snow is bonding to the old surface.
  • Look for signs of instability: whumphing, hollow sounds, shooting cracks, and recent avalanches.
