10-20 cm of new snow with moderate SW winds forming new wind slab in the alpine down to tree line. Watch for buried sun crust on steep solar aspects.

Problems

New wind slab development in the alpine and exposed areas at tree line. Expect these to be reactive to human triggering in the immediate lee of terrain features and in steep gullies.
- Be careful with wind loaded pockets while approaching and climbing ice routes.
- Be careful with wind loaded pockets, especially near ridge crests and roll-overs.
