The strong winds picked up substantial dust and dirt and created a massive dust storm which moved into the greater Phoenix metropolitan area after about 5 pm. Numerous weather spotters reported winds above 40 mph and visibilities below one quarter of a mile in a dust storm. The near zero visibilities created very hazardous driving conditions and led to some traffic accidents. No serious injuries or fatalities were reported.
