Flood Watch Issued for South Central Arizona Through Thursday Afternoon

October 20, 2026 · wweather1 editorial · 2 min read

The National Weather Service in Phoenix has issued a Flood Watch for portions of south central Arizona from Wednesday evening through Thursday afternoon. Excessive rainfall from an incoming storm system may cause flash flooding across the region.

A strong weather system moving into the area will bring widespread showers and thunderstorms, primarily between Wednesday evening and Thursday afternoon. During this period, moderate to heavy rainfall is expected, with localized rainfall rates potentially reaching 1 to 2 inches per hour at times.

The watch encompasses numerous communities across south central Arizona. Affected locations include Central Phoenix, North Phoenix, Glendale, Scottsdale, Paradise Valley, Deer Valley, Buckeye, Avondale, Aguila Valley, Tonopah Desert, Cave Creek, New River, Fountain Hills, East Mesa, South Mountain, Ahwatukee, Apache Junction, Gold Canyon, Queen Creek, Northwest Pinal County, and West Pinal County.

According to the National Weather Service, excessive runoff from heavy rain could lead to the flooding of rivers, creeks, streams, and other low-lying or flood-prone locations.

Residents in the affected areas are advised to stay informed about changing conditions by monitoring subsequent weather reports.
