Avalanche Summary

No avalanche activity has been reported.

Snowpack Summary

Over the last few days, as much as 60 cm of new snow has fallen at upper elevations, accompanied by strong to extreme alpine winds.

Various hard surfaces, including crusts or previously wind-affected snow, may exist below the recent storm snow.

Terrain and Travel Advice

  • In times of uncertainty, conservative terrain choices are our best defense.
  • Start with simple terrain and gather information before committing to bigger features.
  • Continue to make conservative terrain choices while the storm snow settles and stabilizes.
  • Be cautious of buried obstacles, especially below treeline.

Avalanche Problems

Storm Slabs

Recent stormy weather has formed storm and wind slabs, especially concerning at higher elevations. At these altitudes, snowfall has been more consistent, and ground roughness is largely now buried.

Aspects: All aspects.

Elevations: All elevations.

Likelihood: Likely - Very Likely
