The extreme heat has already resulted in 113 heat-related deaths in Maricopa County this year, more than triple the number at this time in 2025. The upcoming thunderstorms could bring additional risks, including strong winds, blowing dust, and flash flooding. Residents in the Phoenix area should remain cautious, especially during the transition from extreme heat to monsoon activity. Those in low-lying areas or near washes should be particularly vigilant for potential flooding. The combination of heat and storms poses a dual threat to public safety.
