Dust Storm in Central Deserts, Arizona

Thunderstorms developed across the central deserts during the late afternoon hours on July 25th, and they generated strong and gusty outflow winds in excess of 40 mph. The winds led to dust storm conditions across portions of northern and central Pinal county, including communities such as Coolidge and Stanfield. A Dust Storm Warning was issued for the area from 1646MST until 1900MST. At 1642MST, a trained weather spotter 1 mile southwest of Coolidge reported dense blowing dust with a visibility of just one eighth of a mile. At 1650MST another trained spotter 6 miles southwest of Stanfield reported near zero visibility in dense blowing dust along Interstate 8 east of Stanfield.
