A round of monsoon thunderstorms moved through metro Phoenix late Sunday into Monday, dropping over an inch of rain in parts of Maricopa County, knocking out power to thousands of customers, and prompting a Flood Watch across the Valley and northern Arizona through Monday. Forecasters flagged Monday as a First Alert Weather Day, with more scattered storms possible and a tropical system in the Pacific being watched for potential impacts later in the week.
How much rain fell and where?
According to the Maricopa County Flood Control District, cited by ABC15, some parts of the Valley picked up measurable rainfall over the 24 hours spanning Sunday into Monday morning, with 12 News reporting that several areas of Maricopa County saw more than an inch of rain by Monday morning. The storms arrived in two waves covered separately by local outlets: a nighttime round on Sunday and a follow-up morning storm on Monday, both tracked live by FOX 10’s Irene Snyder.
Did the storms cause damage or outages?
Yes. ABC15’s live updates from Sunday night tracked a fast-moving sequence of Severe Thunderstorm Warnings across the northern and western Valley, including areas around Anthem, New River, Cave Creek, Glendale, Peoria, Surprise, Wittmann and Beardsley, with wind gusts reported up to 60 mph and at least quarter-size hail near Anthem. Flash Flood Warnings were also issued for Maricopa and Ak-Chin Village.
Power outages climbed and fell in waves as the storms passed through. At different points Sunday night, Arizona Public Service (APS) reported outage counts ranging from about 1,400 to roughly 6,400 customers without power, while Salt River Project (SRP) reported anywhere from about 1,200 to 5,400 customers affected at various times; by later in the night, SRP said it had restored power to most customers, leaving around 1,800 still out, while APS was still reporting about 6,400 without electricity.
What’s the forecast for the rest of the week?
AZFamily reported a 40% chance of Valley showers and thunderstorms Monday, with a cooler-than-normal high of just 96 degrees, and a Flood Watch in effect through noon in the Valley and through midnight in the high country due to continued heavy rain and flooding risk. Drier, slightly warmer weather is expected Tuesday through Thursday before another storm chance returns later in the week.
Meteorologists are also monitoring a tropical system in the Pacific that could pull additional moisture into Arizona from Friday through the Labor Day holiday weekend. That system could bring thicker cloud cover, cooler temperatures and another round of heavy rain, though forecasters say it’s too early to know exactly how it will play out.
Why does this matter for the Valley?
Monsoon storms are a seasonal hazard in Arizona, capable of producing flash flooding, damaging winds, hail and widespread power outages in a short window. The mix of warnings issued Sunday night — severe thunderstorm, flash flood and flood watch alerts stacked across multiple jurisdictions — reflects how quickly conditions escalated across the Phoenix metro and surrounding desert communities, underscoring why local outlets tracked the event in near real time with live outage counts and rainfall tallies.
How does coverage compare across outlets?
Coverage split by format and moment in the storm’s timeline rather than by conflicting facts. ABC15 offered the most granular, live-updated tracking of outages and warnings as the storm unfolded Sunday night, plus a separate rainfall-totals roundup sourced to the county flood control district. FOX 10 covered the story in short video dispatches for both the Sunday night and Monday morning rounds of rain. 12 News focused on rainfall measurements and the broader Monday pattern, including a Flash Flood Watch for northern Arizona. AZFamily took the forward-looking angle, framing Monday as a First Alert Weather Day and previewing the rest of the week, including the Pacific tropical system to watch heading into the holiday weekend.
