Dust Storm in South Central Pinal County, Arizona

Thunderstorm outflow winds produced widespread blowing dust that reduced visibilities to less than a quarter mile and caused traffic disruptions along Interstate 10 in southern Pinal County.

Scattered thunderstorms developed across the Mogollon Rim and International Border during the afternoon and moved west across southeast Arizona through the evening hours. Several storms became severe with damaging winds of 60 to 90 mph that created blowing dust and downed trees and power poles. The most extensive structural damage occurred in the Sierra Vista/Fort Huachuca and Green Valley/Sahuarita areas.
