Problems
Wind Slabs
Windslabs continue to develop today and are still sensitive to human triggering on lee features at treeline and above. Cornices will also be a concern with the new snow and wind.
- Use caution in lee areas. Recent wind loading have created wind slabs.
- Watch for whumpfing, hollow sounds, and shooting cracks.
