It rained a little bit on campus today. About 90 seconds worth. I hadn't noticed until a student came to class with a wet sweatshirt.
I also learned that this weekend's rains, modest as they were, caused flooding in some neighborhoods. There is not much drainage because there typically is not much rain. However, according to my students, rainfall has been increasing dramatically in the past few years. They think it might have something to do with global warming.
Apparently, this is the first October rain Cairo has seen in 10 years.
