Dangerous heatwave scorches US ahead of Fourth of July holiday

A dangerous and prolonged heatwave is currently scorching the central and eastern United States, impacting millions ahead of the Fourth of July holiday weekend. Temperatures, combined with high humidity, are pushing the "feels like" heat index to extreme levels, with some areas potentially reaching as high as 115 degrees Fahrenheit (46 degrees Celsius). This intense weather event is attributed to a "heat dome" settling over the region.

Authorities are warning of major to extreme heat risks, with forecasts indicating numerous daily temperature records could be broken, and some areas may even experience consecutive-day, monthly, or all-time records. Over 60 million people are currently under heat alerts, and the prolonged conditions pose significant health hazards, particularly as limited overnight cooling is expected. Residents are strongly advised to limit outdoor exposure, stay hydrated, and seek refuge in air-conditioned spaces or designated cooling centers to mitigate the risks associated with the sweltering conditions.
