Avalanche Summary
No recent avalanche activity has been reported.
Snowpack Summary
As much as 20 cm of new snow has buried a mixture of moist snow or old crusts. Below the recent snow, the snowpack is generally settled and well-bonded.
Below treeline, slopes are largely below the threshold for avalanches.

Terrain and Travel Advice
- Stay off recently wind loaded slopes until they have had a chance to stabilize.
- Watch for newly formed and reactive wind slabs as you transition into wind affected terrain.
- When a thick, melt-freeze surface crust is present, avalanche activity is unlikely.
