Historic Heat Wave Scorches Eastern U.S., Millions Under Alert

East Coast Braces for Historic Heat Wave Washington D.C. - The eastern United States is currently experiencing its first major heat wave of the summer, with temperatures soaring into the triple digits across several major cities. FOX Weather reports that cities along the Interstate 95 corridor, including Washington, Philadelphia, and New York City, are expected to reach or exceed 100 degrees Fahrenheit. Heat alerts have been issued for over 147 million Americans, as high temperatures are projected to run 10-20 degrees above average. Forecasters warn that the combination of extreme heat and high humidity will offer little relief, even during overnight hours, with nighttime temperatures remaining very warm. This stagnant air mass is preventing any significant cooling, leading to prolonged dangerous conditions. Experts caution the public about the severe health risks associated with such extreme heat, including heat-related illnesses. They urge residents to take precautions, such as staying indoors, drinking plenty of water, and avoiding strenuous outdoor activities. Dozens of century-old heat records are at risk of being broken this week as the heat dome persists.
