Avalanche Summary

One Na size 1.5 avalanche was observed in steep unsupported terrain at treeline.

Snowpack Summary

Strong to Extreme SW winds have redistributed 50cm of storm snow into windslabs at all elevations. This overlies wind-affected old surfaces and pockets of windslab in the alpine and at treeline. The lower snowpack is a variety of old surfaces including facets, crusts, and windslab. A spotty crust exists at the very bottom of the snowpack in deeper locations.

Below treeline windslab overlies settling storm snow and early-season snow in the form of facets and crusts.

Weather Summary

Saturday

Cloudy with PM flurries. Alpine temps -3. Winds moderate SW.

Sunday

Cloudy with flurries. Alpine temps -5. Winds light out of the south.
