episode_narrativeStrong thunderstorms developed in the afternoon over the high terrain of central and southern Arizona before spreading to the lower deserts through the evening, with new development driven mostly by strong outflow boundaries. The primary outflow boundary moved southwest with widespread 30-40 mph wind gusts observed across south-central Arizona and a few stronger gusts, including a 59 mph gust in southern Gila county. The winds were strong enough to cause hundreds of power outages in the Phoenix metro area and generate dense blowing dust over the open deserts in Pinal and western Maricopa counties. With above normal moisture levels, storms also produced localized flash flooding mostly in foothill/high terrain areas, including flash flooding enhanced by recent burn scars.
event_narrativeVisibility briefly fell to 1/4 mile in blowing dust along Highway 347 between Riggs Road and Interstate 8. Blowing dust was generated by a strong northward-moving outflow boundary from storms in northern Pima county and reinforced by a storm near the town of Maricopa. There were no reports of damages or injuries.
