Thunderstorms developed across the central deserts during the late afternoon hours on July 25th, and due to favorable atmospheric conditions, they were able to generate strong and gusty outflow winds in excess of 40 mph. The outflow winds spread across much of the central deserts, including the greater Phoenix area, and generated dust storm conditions. A number of weather spotters reported visibilities at or below one quarter mile in dense blowing dust, and Dust Storm Warnings as well as Blowing Dust Advisories were issued. No injuries were reported due to the dense blowing dust.
