I recently stayed in Karachi, Pakistan for a month, like 5 minutes away from the beach. It rained horribly for a couple of days, and the city's crap drainage system didn't help, so it was still sort of flooded in some parts when I left . In some of the lower parts I think the water got 2-3 feet high. The first day, the power was out basically the whole day and night. In the night temperatures are relatively nice so people like to keep the windows open...long story short, every few minutes we would hear thunder and see lightning flash, which was interesting in the dark with open windows -_-. The second day the power was working, but it rained more, and thunder (really loud, booming stuff that would literally shake you a little bit) and lightning seemed to be almost constant. But after those two days the weather was actually pretty nice.
