UNITED STATES – A powerful heat wave across the eastern United States has killed at least 25 people as extreme temperatures and severe storms disrupted Independence Day holiday events during one of the country’s busiest travel weekends. As of Saturday, the National Weather Service reported nearly 156 million people under heat alerts, with temperatures topping 38°C (100°F) in cities including Washington, DC, Norfolk in Virginia, and Raleigh in North Carolina. Peak heat indexes could reach 46°C (115°F) in some areas, and several cities posted record highs as the prolonged heat placed heavy pressure on regional power grids and strained public infrastructure. WASHINGTON – More than 72 million people were also under severe thunderstorm watches on Saturday, with forecasters warning of wind gusts above 105 kph (65 mph) and hail up to the size of quarters. The storms disrupted celebrations of America’s 250th anniversary of independence in several East Coast cities and forced a roughly two-hour evacuation of the National Mall in the capital. In New York City, authorities opened hundreds of public buildings as cooling centres, deployed volunteers to check on vulnerable residents, and extended public pool hours. Meteorologists said cooler air from Canada is expected to push the heat dome south and west in the coming days, though dangerous overnight heat and humidity will linger, in a warming climate where NASA data show US summer heatwaves have roughly doubled since 1980.
