The parking lot at my old apartment at A&M used to get flooded, and cars would float away. That's what I remember. Of course, this would always happen the first day of school also (or it seemed that way back then).
I would be more concerned about her handling being without electricity for several days. Hopefully she was able to buy some food.
However, I remember that I got stuck at A&M during a snowstorm before classes started for the 2nd semester. We had electricity, but you couldn't drive around. We were stuck in the dorms, and there were no cafeterias open on campus. We had to walk to the grocery store and there was 1 pizza restaurant that was open. We had a blast!!!
Here's praying she has fun if she gets stuck there.
