Dust Storm in Greater Phoenix Area, Arizona

Scattered thunderstorms developed across the greater Phoenix area during the evening hours on September 5th and some of the stronger storms produced gusty outflow winds in excess of 40 mph. The winds stirred up significant amounts of dust and created dust storm conditions which primarily affected the south and southeast portions of the Phoenix area, including the communities of Mesa, Queen Creek and Chandler. According to an NWS employee located 3 miles northeast of East Mesa, dense blowing dust reduced visibility to one eighth of a mile near the intersection of Brown and Ellesworth Roads. This occurred at 1905MST. At 1900MST a trained spotter 2 miles northwest of Chandler reported a dust storm with visibility down to one quarter of a mile at the Chandler Fashion Center Mall. Finally, at 1845MST, local broadcast media passed on a viewer report of visibility down to zero miles in dense blowing dust approximately one mile northeast of Queen Creek. A Dust Storm Warning was issued and in effect at the time of the dust storm reports; despite the very hazardous driving conditions no accidents or injuries were reported as a result of the dense blowing dust.
