I had my sights on Upper Pines this coming weekend, just got robo-called. Yosemite is closed through Sunday March 27th. My reservation has been cancelled and I have been issued a full refund.
It's sounds like it's still pretty hairy up there and there are a few more waves to pass before the weather calms down after the weekend. The next worry will be all this snow melting too quickly.
Best luck to everyone up there.
