PHOENIX, Ariz. – Tropical moisture surging into central Arizona will keep a Flood Watch in effect through Saturday evening, with widespread rain and thunderstorms expected to impact travel, outdoor plans, and desert washes. The National Weather Service in Phoenix warns that heavy downpours could produce dangerous runoff and flash flooding, especially near low-lying areas, dry washes, and major roadways such as I-10, I-17, and U.S. 60.
According to the National Weather Service Phoenix office, rainfall totals of 1 to 1.5 inches are possible across the Valley, with localized higher amounts where storms stall. Communities from Buckeye and Glendale to Mesa, Chandler, and Apache Junction should prepare for ponding on roads and temporary closures along flood-prone routes. Drivers are urged never to cross flooded intersections and to allow extra travel time through Saturday night.
Emergency management officials encourage residents to charge devices, clear drainage areas, and avoid hiking trails, washes, or desert crossings until rainfall subsides. Those living in flood-prone neighborhoods should stay alert for Flash Flood Warnings and be prepared to move to higher ground if conditions worsen.
Drier and cooler fall weather will return by Sunday, bringing a much-needed break from the tropical surge. By early next week, high pressure builds, allowing sunshine and seasonal temperatures—ideal for fall events, pumpkin patches, and leaf-viewing trips across the East Valley.
