The National Weather Service in Phoenix issued a Flood Watch Saturday covering Scottsdale, Paradise Valley, and a broad swath of south-central Arizona, effective through 5 a.m. Sunday, Aug. 30.
The watch spans the Phoenix metro, all of Gila and Pinal counties, and much of Maricopa County, including Cave Creek, New River, Deer Valley, Fountain Hills, the East Valley, Apache Junction, and Queen Creek, among other areas.
Increasing moisture and atmospheric instability, combined with an approaching weather system, are expected to produce scattered thunderstorms capable of heavy rainfall from late Saturday afternoon through Saturday night. The NWS warns that storm training could result in localized rainfall totals exceeding two inches within the watch area.
Excessive runoff may cause flooding of rivers, creeks, streams, and other low-lying and flood-prone locations across the region.
Residents should monitor updated NWS forecasts and be alert for possible Flood Warnings. Those in flood-prone areas should be prepared to take action if flooding develops. Additional safety guidance is available at weather.gov/safety/flood.
The watch expires at 5 a.m. MST Sunday; an updated NWS forecast is expected before then.
