Flooding poses risks to residents in affected counties, including Maricopa, Pima, Navajo, and Coconino. River flood advisories in Greenlee and Graham counties indicate potential overflow and localized flooding near waterways. Residents should remain vigilant as floodwaters can disrupt transportation, damage property, and pose safety hazards. Prolonged warnings suggest sustained risks in certain areas, particularly Maricopa County, where advisories extend into Saturday.
