Avalanche Summary
No new avalanches have been reported.
Snowpack Summary
20 to 30 cm of dry new snow sits over a crust or moist snow. At upper elevations the new snow has likely been redistributed by wind.
The mid and lower snowpack is generally uniform, with no significant layers of concern.
Below treeline, most areas are below threshold for avalanches.

Terrain and Travel Advice
- The new snow may require another day to settle and stabilize.
- Closely monitor how the new snow is bonding to the crust.
- Start on smaller terrain features and gather information before committing to bigger terrain.
- Look for signs of instability: whumphing, hollow sounds, shooting cracks, and recent avalanches.
