Extreme Heat and Storms Grip U.S. Regions

Much of the United States is under heat advisories or extreme heat watches, with regions such as Savannah, Central Florida, New Orleans, and parts of Mississippi experiencing highs in the 90s and heat indices over 100°F, leading to frequent afternoon storms and localized flooding. Southern Nevada faces particularly hazardous conditions, with temperatures forecast to reach up to 120°F under an Extreme Heat Watch. The Northeast contends with high humidity, thunderstorms, and periodic downpours, though some relief is expected by midweek. Alaska remains cooler and cloudy with rain showers and elevated river levels, but no heat concerns. Flash flood risks continue in select areas due to recent rainfall. There is currently low tropical storm activity in the Atlantic, with no new developments expected soon.
