I heard the chopper but didn't have any idea how tragic the news would be:

I climbed Casaval on Saturday morning and didn't see a single falling rock although I did start from the car at 1:30AM. There was some ice raining down from above on the slope below the catwalk around 8AM but that was it. (It's off this topic, but the upper parts of the mountain were in amazing shape - the rocks at the top of Casaval are still heavily coated in rime and the catwalk is still very wide.)
Be careful out there!
