The National Weather Service issued a Flood Advisory for Maricopa County effective August 9 at 9:21 PM MST through August 10 at 12:15 AM MST. Doppler radar indicated heavy rain from thunderstorms, with between 0.25 and 1 inch of rain already fallen. Minor flooding is ongoing or expected to begin shortly in low-lying and poor drainage areas, with dangerous flows over low-water crossings and water over roadways.
Affected locations include Glendale, Avondale, Goodyear, Buckeye, Tolleson, Luke AFB, and Phoenix International Raceway, among others. An additional 0.25 to 1 inch of rain is expected, which will result in minor flooding. The National Weather Service advises turning around and not driving through flooded roads, as most flood deaths occur in vehicles.
