The mid-Atlantic and Carolinas face significant flash flooding risks, particularly in areas like Norfolk, Virginia Beach, and eastern North Carolina, where rainfall could reach 8 inches. Flooding may disrupt travel, damage property, and pose safety hazards. Meanwhile, the Gulf Coast, Central U.S., and Southern Plains are under high risk for extreme heat, with heat indexes as high as 115°F (46°C). Vulnerable populations, including children, the elderly, and outdoor workers, are at heightened risk of heat-related illnesses. NOAA also predicts a heat dome over Texas and the southern Plains into early August, exacerbating heat stress.
