Talked to my brother in San Diego. It's bad there... thankfully, his home is OK, but one street away, flooding, 2 feet of water running in the street and into driveways.
We had "100 year" floods 2 years in a row, in Phoenix, in 1979 and 1980. It was hell. The bridge over 1-10 was washed out, I had to leave for work at 5 AM and leave an hour early to get home in 2-3 hours, for 6 weeks, the second time. The first year, I lived/worked on the same side of the river (normally a dry wash), but I couldn't go anywhere else, including to my parents' 4 miles away, outside of Tempe. I hope the infrastructure is better today because the rain is heading east.
