The August 28 monsoon has turned out to be one of the worst in recent history, perhaps extended history. A condo building in downtown Phoenix lost its roof, several trees were uprooted, and a friend of mine caught a pic of a palm tree flattening a car near ASU. Add to this that the 100 mile/hour winds in parts of the city rivaled a Category 1 hurricane and well, you've got a city in shambles.
The following photos came from here.
The aforementioned building roof.
I have some pics I took myself that I'll upload later...but this just gives you an idea of the kind of fury we're subject to in "the land without natural disasters."
