The National Weather Service in Phoenix issued a Flood Watch at 12:45 a.m. Wednesday covering all of Maricopa County, including Scottsdale and Paradise Valley, with the alert running through 11 p.m.
The NWS says a combination of abundant moisture and an incoming weather system will drive rounds of showers and thunderstorms through the evening. Rainfall rates in excess of 1 to 2 inches per hour are expected with most storms. Some areas face the additional risk of training storms, a pattern in which successive cells move over the same ground and produce high rainfall accumulations.
The watch covers a broad swath of south central Arizona, extending from the Aguila Valley and Gila Bend in the west through the Tonto Basin, Mazatzal Mountains, and Globe/Miami area in the east, and south into Pinal and Gila counties.
Excessive runoff may result in flooding of rivers, creeks, streams, normally dry washes, and other low-lying and flood-prone locations, according to the alert.
Residents should monitor later NWS forecasts and be prepared to take action if a Flood Warning is issued. The NWS flood safety resource is available at weather.gov/safety/flood.
