Published:

Locally unstable conditions with storm slabs. Keep good distance to avalanche terrain and run-out zones.

New snow (slab avalanches)

Buried weak layer of new snow

Look for cohesive new snow that breaks apart or is poorly bonded to the old snow. Cracks around your skis are a typical dangersign.
