More detailed information about the avalanche: 

Several new avalanches occured today with the arrival of +10cm/4" of new snow above 8000'. Most of the visible avalanches were superficial point releases but have entrained enough snow to bury an individual. The winds have created leeward slabs on aspects near & above treeline which face North-East-Southeast. There is a Storm Slab component to the avalanche hazard as the new accumulation sits atop a variable spring bed-surface. Some areas of the old snow are refrozen & icy while others are almost slush or completely rotten to the ground.  Tracks in & around the avalanche activity are concerning but at most the avalanches are of the R2-D2 realm. More snow to come, be prepared to use your rescue skills.

More detailed information about the weather: 

Swirling Light to Moderate winds from the South-West-Northwest was blowing snow into banners from ridgetops. Temperatures were in the mid-40Fs near 8000' with a low of 25F at 9600'. Intermittent sun was poking through the clouds & zapping the new snow. The snow had brief moments of intensity but was battered by winds forming deposits near 6" deep. When calm falling flakes were stuck together by the dozen.
