Heat Wave Triggers ER Visits Surge as Northeast Braces for More Heat

A multiday East Coast heat wave has driven CDC-reported “extremely high” rates of heat-related illness to emergency rooms, with Washington, DC near 102°F and New York City and Philadelphia around 100°F (heat indices near 105). A Pennsylvania death linked to heat exhaustion was noted as cooling centers open, power outages strain the grid, and some Fourth of July events are canceled or delayed. Officials warn of continued hot conditions into Saturday and urge hydration, breaks in shade or indoors, and checks on vulnerable populations. Experts also say fossil-fuel pollution amplified the heat.
