I was there yesterday too! The rain was intense, your pictures didn't even cover the half of it. I was surprised at what stayed open, though. I got a chance to ride Nitro (hey, I liked Nitro in the rain), S:UF, and Medusa, while I saw El Toro and GASM stay open as well.
We wanted to ride The Dark Knight, but when we got on the line they said that it wasn't working and we decided it wasn't worth waiting in the rain (that, and on the way there, we heard some kids complaining, "They took Chiller out for THAT?!")
Plus, they closed Medusa so we could have mass, and wouldn't you know it, the sky almost totally darkened during it and we had to sit for almost an hour in the pouring rain, not fun.
