Weakening snow surface on old avalanche bed surfaces could allow the patchwork of bed surfaces below 7500' to produce future "repeater" avalanches. Now is a good time to memorize the pattern, before the evidence is buried by the next storm. The weak snow in this video is just 8" thick and sitting directly on the very hard 12/16 rain crust. I think the colder inverted temperatures in the valley, could weaken the lower elevation snow surface more than the higher elevations.

Photos of widespread surface hoar at all aspects and elevations. Like Mark White's comments farther South, it is worth noting that these faceted crystals now exist on the regular ski runs. And not just in typical sheltered areas. If it survives intact and is buried during the next storm, it could be an unusually widespread persistent layer.
