The storm system is expected to bring localized flooding risks, particularly in Yuma and Maricopa counties. Thunderstorms may produce heavy rain, lightning, and small hail in some areas. Increased winds could also pose risks, especially for outdoor activities. Residents in flood-prone areas should be prepared for potential evacuations and avoid driving through flooded roadways. The Flood Warning remains in effect until Tuesday morning. (Source: FOX 10 Phoenix, Source time: not specified)
