Avalanche Summary
No new avalanches have been reported in the past few days. We suspect rider triggerable wind slabs will be found on Thursday.
Snowpack Summary
New snow with southwest wind is falling onto a hard melt-freeze crust at all elevations. Wind slabs are likely forming in lee terrain features at higher elevations. This new snow may take time to bond to the crust.
The remainder of the snowpack is consolidated and strong.

Terrain and Travel Advice
- Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
- Closely monitor how the new snow is bonding to the crust.
Problems
Wind Slabs
New snow and southwest wind may form wind slabs at treeline and above. The underlying crust may prevent wind slabs from bonding, resulting in larger and more reactive slabs.
