Weather

Strong NW wind blowing snow ATL in the AM, warm for Feb., few clouds streamed by mid-day.

Snowpack

Below treeline(NE), the snowpack is mostly cohesionless. Near and above treeline, wind and persistent slab structures can be found on isolated leeward slopes. Snowpack test results(HS:140cm) showed propagating failure mid-pack under a newly formed slab among strong and weak persistent layers. A previous pit(1/29, HS:110cm) in the same location showed non-propagating failures due to a lack of a cohesive slab.

Avalanche

Recently reported. Small(~30'x20'), loose dry, directly below drifted ridgeline.
