A dangerous and record-breaking heatwave is gripping the eastern United States, forcing communities to alter or cancel their Fourth of July celebrations as the long holiday weekend approaches.
The oppressive conditions are expected to dampen spirits at many events marking 250 years of American independence.
Hazardous temperatures will persist across much of the central and eastern U.S. through Friday, extending along the East Coast through the weekend, the National Weather Service said. Forecasts predict temperatures in the high 90s Fahrenheit for the Northeast, with Philadelphia and Boston potentially exceeding 100 degrees. High humidity is expected to make conditions feel even hotter.
