25 dead in ongoing heat wave as storms bring flood, wind threats to East Coast
A weeklong heat wave gripping the East Coast, Southeast and Southwest has produced at least 25 deaths and left about 40 million people under heat alerts as record-high temperatures and dangerous heat indices persist. Throughout July Fourth weekend, numerous cities saw new highs and emergency-room visits rise, while forecasters warned of continued heat, with potential 2-inch-per-hour rainfall and flash-flood risks from advancing storms. The outlook anticipates a gradual cooldown later in the week, though lingering storm threats and flood alerts remain in effect for much of the region. Authorities and meteorologists stress the need for hydration, cooling measures, and vigilance for rapid weather changes as conditions evolve. The episode underscores how prolonged heat intertwines with severe storms to stretch public health and infrastructure systems over multiple days.
