Weather

12" of new snow with 1.15" of water content. It looked like the storm was moving out around mid-morning, but snow moved back in and light snow continued all day with an additional 2-3" by 1700. Temperatures were in the teens and moderate SSW winds caused moderate wind transport near treeline.

Snowpack

Found reactive soft storm slabs on windloaded NE-E aspects near treeline. Avalanches were triggered at the new snow/old snow surface interface. Found no signs of instability on north aspects below treeline.
