The National Weather Service issued a Flood Advisory for Maricopa County in south central Arizona, effective from 10:13 PM MST on August 9 through 1:15 AM MST on August 10. Heavy rain from thunderstorms has already dropped between 0.25 and 1 inch of rainfall across the area, with minor flooding ongoing or expected to begin shortly in low-lying and poor drainage areas.
Additional rainfall of 0.25 to 1 inch is forecast, which will result in continued minor flooding. Some low-water crossings may become impassable. The advisory primarily affects rural areas of Maricopa County, including drainages such as Flying E Wash, Jimmie Wash, Grass Wash, Star Wash, Mill Wash, and the Hassayampa River. The National Weather Service advises residents to avoid flooded roads; most flood deaths occur in vehicles attempting to cross flooded areas.
