The southeastern half of Arizona faces the highest risk of flash flooding and strong thunderstorms, which could bring high winds and dust. In Phoenix, scattered showers may cause localized disruptions, but the risk of severe weather is lower. Residents in flood-prone areas should remain vigilant and prepared to evacuate if necessary. Rising waters and flooded roads pose significant hazards, and drivers are advised to avoid water-covered roadways. Heat-related illnesses remain a concern, with temperatures expected to stay near or slightly above 100°F (37.8°C) through the weekend.
