Avalanche Summary

There have been no reports of avalanche activity in the past 2 days.

Snowpack Summary

Expect to find 5-15 cm of new snow sitting on the snow surface above 1500 m. This is likely being redistributed by primarily southwest wind in alpine and treeline lee terrain. It likely sits on a crust or moist snow except on high northerly aspects where the snow has stayed dry.

The lower snowpack is settled and well bonded.
