Avalanche Summary
A size 2 natural slab avalanche was reported on Thursday but the avalanche likely occurred on Wednesday. Click on the picture for more details.
Snowpack Summary
Variable surface conditions exist at all elevations. New surface hoar has formed at treeline and below in sheltered terrain. South facing slopes has a mix of scouring, wind hammered surface snow, a crust and potentially moist snow in the afternoon. Soft snow can still be found on sheltered north facing terrain.
A layer of surface hoar may be found down 20 to 60 cm in north facing, sheltered terrain. It may be an isolated problem at the moment but good to try to get some observations or test suspect slopes before jumping into your line.
A thick melt-freeze crust is found down 50 to 100 cm below 1500 m. this layer is not currently a concern.

Terrain and Travel Advice
- Seek out sheltered terrain where new snow hasn't been wind-affected.
- Carefully evaluate steep lines for wind slabs.

Rider triggerable wind slab may still be found near ridge crests. They will likely be more reactive if they overlie facets or surface hoar.
