    There are variable wind slabs throughout the region. Be extremely cautious in terrain traps where even a small slide could have dangerous consequences. Higher Consequence above 2400m due to lack of new rain crust.

Snowpack Summary

New rain crust to 2400m. 5-10 cm recent storm snow sits above this new Nov crust. Total snow pack height in alpine 45-85 cm. Snowpack sits atop a weak basal crust from Oct 07.

Avalanche Summary

From Friday: Natural avalanche cycle up to size 2 were mostly loose point release on all aspects at treeline. They remain relatively small. One slab release size 2 on Parker Slabs from steep deposition zone showed good propagation likely on the basal crust. Visibility was limited. No new avalanches observed Sunday

Confidence

Due to the number of field observations
