PHOENIX, Ariz. – Heavy rain continues to drench central Arizona this Saturday morning, with flash flooding still a serious concern for travelers and residents through Columbus Day. Flood Watches remain in effect across Maricopa, Pinal, and Gila counties as tropical moisture fuels repeated rounds of thunderstorms. Drivers should expect ponding along I-10, I-17, and local roadways, and delay travel if possible.
According to the National Weather Service in Phoenix, rainfall totals of 1 to 2 inches are likely through Sunday evening, with some areas exceeding 3 inches where storms train. Urban flooding is possible in Glendale, Scottsdale, and Mesa, especially in low-lying and poor drainage areas. The heaviest rain is expected Saturday afternoon and Sunday morning before tapering by early Monday.
City and county officials urge residents to keep devices charged and avoid flooded washes. The “Turn Around, Don’t Drown” warning remains in effect across Maricopa County. Cooler, drier air will follow the system, setting up a pleasant, sunny stretch for midweek—ideal for post-holiday travel and outdoor fall events.
By Monday afternoon, skies begin clearing, and highs dip into the upper 80s. Fall sunshine will return Tuesday, offering a break for pumpkin patch visits and fall festivals. Another weak front late next week may bring slightly cooler mornings, signaling an early taste of the desert’s slow shift toward late-October chill.
