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
Problems
Wind Slabs
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.
- Be careful with wind loaded pockets, especially near ridge crests and roll-overs.
- Use caution in lee and cross-loaded areas. Recent wind loading has created new wind slabs.
