We had a pretty heavy group of storms move through Tucson today and it started while I was driving to work. I took a few pictures.
If you're not from Tucson (or Arizona) then you're probably wondering what the big deal is. Its just a rainstorm. But it doesn't rain that often here (it's the desert!) so its one of the most extreme weather events that occurs here. The ground is mostly clay and very hard so flooding occurs very easily.
