FLOOD ADVISORY: The National Weather Service in Phoenix issued a Flood Advisory for Maricopa County Tuesday evening, effective at 8:27 p.m. and running until 10:30 p.m. MST, citing heavy rainfall from thunderstorms producing minor flooding in low-lying and poor drainage areas.
Doppler radar and automated rain gauges confirmed between 0.25 and 1.25 inches of rain had fallen across the advisory area by 8:27 p.m., according to the NWS alert. An additional 0.25 to 0.75 inches were expected, enough to sustain minor flooding conditions.
Affected drainages include Camp Creek, Cave Creek, Grapevine Wash, Seven Springs Wash, Rodger Creek, Blue Wash, Cottonwood Creek, Apache Wash, New River, and Galloway Wash. Locations expected to see flooding include Scottsdale, Cave Creek, Carefree, Desert Mountain, Camp Creek, and Seven Springs.
The NWS cautioned that rises in small streams and normally dry arroyos are occurring or imminent, with ponding of water in urban areas expected. Nighttime conditions increase risk, the agency noted, as darkness makes it harder to recognize flooding hazards. Residents are urged to report observed flooding to local emergency services.
The advisory expires at 10:30 p.m. MST; check weather.gov/safety/flood for updates.
