This from a post on Yosemite News and Discussion group by someone who is very familiar with the park and its staff:
"Convoys are meeting at El Cap Meadow at 1100am and 1200pm for Wawona exit. May also exit via Crane Flat to Tioga Pass only (this route is dependent on fire behavior and could close at any moment). Must leave the valley by 1200pm today."
Very sad news.
