A dangerous and potentially record-breaking heat wave is set to grip the eastern half of the United States ahead of the Fourth of July holiday, placing millions at risk as they prepare for outdoor celebrations. The intense heat, driven by a persistent high-pressure system, will spread from the Midwest to the Northeast, peaking by the holiday weekend.
Temperatures are expected to climb near or above 100°F (37.7°C) in many areas, with humidity pushing “feels like” conditions beyond 110°F (43.3°C). Officials warn that the lack of overnight cooling will worsen the impact, as consecutive hot days and unusually warm nights increase the risk of heat-related illnesses. More than 100 million people are under major to extreme heat risk alerts.
Health experts emphasize that extreme heat remains the deadliest weather hazard in the United States, surpassing fatalities from hurricanes, tornadoes, and lightning combined. The growing frequency and intensity of such heat waves have been linked to human-driven climate change, with similar extreme events recently recorded in Europe.
With millions expected to attend parades, cookouts, and fireworks displays, authorities urge precautions during peak afternoon and evening hours.
