Residents in Phoenix, Tucson, and southeastern Arizona should prepare for potential severe weather, including strong winds, blowing dust, and heavy rainfall. The I-10 corridor between Phoenix and Tucson is particularly at risk. Flooding is a concern in areas under the flood watch, especially in southern Arizona. Reduced visibility from blowing dust could impact travel, and localized flooding may occur in low-lying areas. While temperatures will be cooler than average, the storms could disrupt outdoor activities and pose safety risks.
