More detailed information about the avalanche: 

Many small Loose wet avalanches were observed. East aspects get the earliest rays & have a long duration of sun. By early afternoon the snow surface was wet & minor sluffs & rollerbisalls were everywhere. Wind scoured ridges were firm with shallow winds slabs below that were unreactive to foot travel. Fantastic splitboarding! Corn snow mixed with broken precip particles made great surface snow.

More detailed information about the weather: 

Clear sky with zero clouds. A mild haze, likely from sublimating snow. Winds were 1-5 mph from the North, at ridgeline they were gusty to near15 mph. Sunburn? An inversion held overnight with a 6F degree difference between Leavitt & Sonora Snotels. Excersize caution today as wet snow has not refrozen. In my sample location at 9100' on a NW aspects it was 6.9C (44F), with a Height of Snow HS140cm, the Temperature of the surface snow Tsurf 0.0C. Blowing snow was seen at ridgeline.
