Thunderstorms developed across portions of south central Arizona, including the greater Phoenix metropolitan area, during the evening hours on August 10th. Due to high levels of moisture and instability in the atmosphere, some of the storms produced very heavy rainfall with peak rain rates in excess of 2 inches per hour. The heavy rain led to episodes of flooding across portions of the central deserts, including the community of Buckeye. The flooding led to the closure of various roads, including highway 238 just to the northwest of Ak-Chin Village. Isolated thunderstorms also generated gusty and damaging outflow wind in excess of 50 mph which caused damage to trees and power poles in the town of Buckeye. The flooding led to the issuance of Urban and Small Stream Flood Advisories but no Flash Flood Warnings.
