Confidence

Moderate

  • We are uncertain due to a limited number of field observations.

Avalanche Summary

Numerous size 1 dry loose avalanches were observed in steep features, and a few windslab avalanches to size 2 were observed Monday morning.

Snowpack Summary

40 cm of new snow is being redistributed into wind slabs in lee features. This sits over older wind slab in the alpine and over a new crust treeline and below treeline. Beneath this, 30–50 cm of settled snow overlies crusts and facets which is all moist treeline and below treeline. This moist snow is starting to refreeze due to colder temperatures. The lower snowpack is generally well settled.

Terrain and Travel Advice

  • Watch for newly formed and reactive wind slabs as you transition into wind-affected terrain.
  • Loose avalanches may step down to deeper layers, resulting in larger avalanches.
