I just so happened to crest a ridge and look over at the Big Horseshoe and WATCH two avalanches release naturally. Spectacular! The southwest wind was blowing enough to produce plumes and there is no doubt that the added weight of the wind drifted snow pushed the weak snowpack over the edge.
The photo below is of two different avalanches that released either late Thursday or early Friday. I took the photo on Friday but highlighted in red the two avalanches that I watched release today.
