Weather

A few clouds and mild temps. A brief period of moderate NE winds with some wind transport, but onto aspects with spotty coverage. HN/W; 1.5"/0.15". HST/W; 9"/0.6". Significant settlement in the new snow, 9" settling to 4-5" in less than 24 hours.

Snowpack

Isolated, small triggered activity (D1) with ski tests in steep N-NE aspects near and below TL. Warming temps in the afternoon produced numerous wet rollers on sunny aspects, but they couldn't get themselves organized into an avalanche.

Avalanche

No observed avalanche activity along the highway corridor and in the Weminuche and South San Juan Wilderness areas.
