In-Depth Analysis
The National Weather Service (NWS) issued blowing dust advisories for much of southern Arizona, highlighting the risk of strong thunderstorm outflows producing gusts of 40-45 mph. These conditions can lead to haboobs, massive dust clouds that cause near-zero visibility. The advisories covered areas including the Tucson metro area, western Pima County, and parts of Pinal and Graham counties.
Authorities anticipated that outflow-driven blowing dust would move westward across southeast Arizona during the afternoon, affecting central Pima and southeast Pinal counties in the late afternoon and evening. Motorists in the impacted areas were urged to remain alert and follow local weather guidance.
