I lived in PV and Scottsdale from '59 until 5 years ago, when I moved to the mountains. During the 60s we had one of those roll in from the east every day at 4:30 PM during the monsoon season. You could set your watch by it. We would see that front wave coming all the way from the Superstition Mountains (we lived on the south slope of Mummy Mountain, north of Camelback Mountain), and the dust storm would roll across the Valley knocking out power everywhere and leaving a lot of destruction in its wake. During the stronger storms, it was not unusual for many homes and businesses to lose roofs. Of course, the dust storm was followed by big thunderstorms. Power outages were standard, and we always had a good supply of lanterns and candles at the ready. Driving in them is a bad deal, visibility drops to nothing, and paint, windshields and trim will be badly sandblasted, if you don't have an accident. All the development since the 70s has greatly reduced the frequency and severity of the storms, as there is less dirt to pick up, and somewhat less convection to feed the intense T-storms, the outflow of which causes the dust storms. Big ones still occur frequently around Casablanca Grande, causing large-scale wrecks on I-10.
Those storms also cause a lot of havoc if you're flying -or turbulence, zero visibility and, if one is foolish enough to fly into it, lots of damage to the airplane (and that is in a light storm, hate to see what would result from penetrating a heavier storm, like the one in the original post.
