Residents in Phoenix and southern Arizona should prepare for potential severe weather conditions, including strong winds, heavy rainfall, and blowing dust. The flood watch in effect for southern Arizona highlights the risk of localized flooding, particularly in low-lying areas. Travelers along the I-10 corridor between Phoenix and Tucson may face hazardous driving conditions due to reduced visibility from blowing dust. While temperatures are expected to be slightly cooler than average, the storms could disrupt outdoor activities and pose risks to infrastructure and property.
