The National Weather Service in Phoenix cancelled the Flood Watch for Scottsdale/Paradise Valley and 16 other areas across the greater Phoenix region, effective as of a 1:06 a.m. Sunday alert, after the first round of rainfall wrapped up with only isolated showers expected through Sunday morning.
Flooding is no longer expected to pose a threat overnight, the NWS said, but residents should not stand down entirely. A second round of showers and storms is forecast for Sunday evening, with heavy rainfall and localized flooding possible Sunday evening into early Sunday night, particularly across Maricopa and Pinal counties.
The cancellation covers a wide swath of the Valley: Aguila Valley, Buckeye/Avondale, Cave Creek/New River, Central Phoenix, Deer Valley, East Valley, Fountain Hills/East Mesa, Mazatzal Mountains, New River Mesa, North Phoenix/Glendale, Northwest Valley, Rio Verde/Salt River, Scottsdale/Paradise Valley, South Mountain/Ahwatukee, Southeast Valley/Queen Creek, Tonopah Desert, and Tonto Basin.
The NWS advises residents in flood-prone areas to be prepared to take action if flooding develops Sunday evening, and to continue heeding any remaining road closures from the overnight storm.
The NWS Phoenix forecast office is expected to issue updated watches or warnings ahead of the Sunday evening storm window; the current alert expires at 5 a.m. Monday MST.
