Nearly 200 million people in the United States, or 60% of the U.S. population, are under a heat advisory or flood warning or watch as high temperatures spread and new areas are told to expect severe storms.
The National Weather Service said a “dangerous” heat wave began to scorch the Northeast and mid-Atlantic on Thursday and will continue into the weekend. Severe thunderstorms and flash floods are possible for parts of the Northeast and South, New England and South Florida. Meanwhile, the string of record-breaking temperatures will persist for the Southwest and Midwest.
