Event narrativeevent_narrativeScattered thunderstorms developed across portions of central Arizona, including the greater Phoenix area, during the afternoon hours on August 2nd. Due to very high moisture levels in the atmosphere, a Flash Flood Watch had been issued for the area from noon through midnight. Some of the thunderstorms affected communities such as Scottsdale, Paradise Valley and Deer Valley, and they did produce locally heavy rainfall. A variety of spotters reported heavy rain with rainfall rates well in excess of one inch per hour. For example, at 1709MST a trained spotter 3 miles southwest of Desert Ridge Marketplace measured 0.58 inches of rain within 20 minutes. At 1650MST, another nearby spotter reported the curb lane on 32nd Street was flooded and impassable. Additionally, at 1811MST a trained spotter 2 miles southwest of Fountain Hills measured 0.52 inches of rain within 30 minutes and reported that the wash behind his house was running. A Flash Flood Warning had been issued for communities such as Scottsdale, Desert Ridge and Carefree, from 1641MST through 1845MST, however significant flash flooding was not observed. Instead, there were instances of urban flooding reported, including flooding of local streets and washes.
