Episode narrativeepisode_narrativeA large convective complex formed over south central Arizona during the early morning hours on August 23rd, a result of a weather disturbance acting on a very humid and unstable airmass. The complex of thunderstorms produced locally heavy rain across much of south central Arizona, including the greater Phoenix metropolitan area, beginning shortly after midnight and persisting through sunrise. Peak rainfall rates were between 3 and 4 inches per hour, and the heavy rain led to episodes of flooding and flash flooding, affecting areas from Witmann and New River south through the central portions of Phoenix. Several Urban and Small Stream Flood Advisories were issued for the event, but no Flash Flood Warnings were issued, despite the fact that a Flash Flood Watch remained in effect through 5 am.

An Urban and Small Stream Flood Advisory was issued for northwest Maricopa county, including Wittmann, beginning at 1 am and continuing through 4 am. At 125 AM, a Flood Control District rain gage located 10 miles northwest of Wittmann, measured 1.73 inches of rain at Daggs Wash. The rain fell in a one hour period of time.
