More detailed information about the avalanche: 

Many Loose Wet Point-Releases are visible on most aspects where the recently deposited 4-6" of new snow stuck. Winds from the SW-W-NW helped deposit snow onto SE-E-NE aspects in the near & above treeline areas. Slab development has not been a major factor from what I have observed. The avalanche event photographed was several Loose-Wet slides that congregated in one terrain trap zone. All of the avalanches originated high in the starting zone on slopes steeper than 42 degrees, near & around rocks. Estimated at R2 in size but pushing D2.5- D3 in destructive potential. Enough snow was entrained to definitely bury a car & this was the largest of the avalanches observed in both Virginia Lakes & the BWRA.

More detailed information about the weather: 

Quite cloudy with calm to light winds from the W-SW. The new snow that fell landed on a wet bed-surface & much melted immediately. The snow that prolonged became wet & acted as Loose Wet (Point release) avalanches do. Skiers that I spoke with said it was fun & styrofoamy with a semi-hard sliding surface on exposed ridges. Sluffs were visible within ski tracks on NE-E aspects.
