Millions across the Eastern United States are facing a dangerous heatwave, with temperatures projected to hit 38C (100F) for multiple days. The National Weather Service warns that the heat index in cities like New York, Philadelphia, and Washington DC could soar to 115F during the Independence Day weekend.
This extreme weather coincides with high-profile events, including President Donald Trump’s planned outdoor 4 July celebration and various outdoor World Cup matches. In New York, where officials like Mayor Zohran Mamdani are urging residents to remain indoors, pop star Taylor Swift and NFL player Travis Kelce are reportedly holding their wedding at Madison Square Garden.
The current conditions, driven by a persistent high-pressure system known as a heat dome, have been exacerbated by dry soil following a period of drought in the Northeast. Similar extreme conditions are impacting Canada, leading to the cancellation of public World Cup watch parties in Toronto. While forecasters expect a slight cooling trend by Sunday as a northern weather system arrives, the event underscores a global trend of more frequent and intense heatwaves linked to climate change.
