US heatwave disrupts 250th anniversary Fourth of July celebrations
An intense heatwave across the eastern United States has forced the cancellation or rescheduling of several Independence Day events, including parades and festivals, raising health concerns.

The United States is preparing to celebrate its 250th birthday, but a severe heatwave has settled over much of the eastern part of the country, prompting officials to warn of serious health risks. Temperatures are exceeding 38°C (100°F) in many areas, with high humidity making it feel even hotter.
Some celebrations have already been disrupted. The Great American State Fair in Washington, D.C., temporarily closed when temperatures reached 39°C (102°F). In Philadelphia, the Salute to Independence Parade was canceled, and several events in Pennsylvania were postponed or called off. Amtrak has canceled multiple trains in the Northeast and warned of delays, as extreme heat can cause rails and bridges to expand.
Cities are taking precautions. New York City has deployed over 200 teams to check on homeless individuals and direct people to cooling centers, including air-conditioned public buildings and mobile vans. Mayor Zohran Mamdani urged residents to stay indoors and set air conditioners to 26°C (78°F) to avoid straining the power grid. Boston is offering free admission to air-conditioned museums, while Providence, Rhode Island, has extended pool hours.
Health authorities recommend drinking plenty of water, taking breaks in the shade, and limiting alcohol consumption. Signs of heat illness include cramps, rapid pulse, heavy sweating, hot red skin, dizziness, and nausea. Immediate medical attention is advised if symptoms appear.
