Problems
Wind Slabs
Previous strong SW winds have created wind slabs in alpine. Forecast winds and snow will increase the size and likelihood of triggering, and slabs may start to form at treeline.
- Be careful with wind loaded pockets, especially near ridge crests and roll-overs.
- Watch for surface cracking and stiffer surface layers of snow. Avoid wind loaded terrain.
