Tornado?

So, I'm chillin this afternoon, when I here this dull roar. I thought, is that a vacuum, or a siren. Well, turns out it was the city tornado siren. First day of class & I had to run around the dorm to tell everyone to get in the basement. Needless to say it was hot and stinky after about 10 minutes. Finally we got to leave after about 1/2 an hour. No tornado, just lots of lightening and tons of rain in a very short time. A few buildings on campus had some flooding. A few leaks in J. Alvin, but no big deal. Only the third time it's rained since we've been here, but every time it comes on super fast.
