Avalanche Summary

There were reports of numerous skier controlled dry loose and wind slab avalanches to size 1 and 1.5 on Sunday.

Snowpack Summary

20 - 30 cm of new snow has accumulated over a crust at most elevations.

There is a layer of sugary facets that are buried 30-50 cm deep and in some places may sit on a crust. Avalanches on this layer are unlikely, but we continued to monitor its reactivity.

The lower snowpack contains a series of crusts and faceted snow that are more prominent in shallow areas in the east and north of this forecast region.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
  • Wind slabs may be poorly bonded to the underlying crust.
