Heatwave disrupts July 4
The United States marked the 250th anniversary of independence on Saturday as a heatwave bore down on millions across multiple states and disrupted July 4 plans, with the National Weather Service warning that "numerous daily temperature records are expected today and Independence Day."
“"numerous daily temperature records are expected today and Independence Day"”
In Washington, D.C., the Great American State Fair was closed for several hours Friday afternoon and the Independence Day parade scheduled for Saturday was cancelled due to extreme heat, while the National Mall events were partially postponed after people required medical attention.
The heatwave also strained power grids, with ABC News reporting that "nearly 800,000 customers" were without power as outages were reported across multiple states.
In New York City, the heat index climbed to about 105F (41C), prompting authorities to open cooling centres and extend public swimming pool hours, and in Philadelphia and Washington, D.C. temperatures were expected to endure a third consecutive day of triple-digit temperatures.
Across the eastern U.S., forecasters warned that extreme heat and humidity could spark severe thunderstorms, with ABC News saying the primary hazard on Saturday was damaging wind gusts.
Trump’s speech and politics
As the heatwave disrupted celebrations, President Donald Trump delivered a speech at Mount Rushmore on Friday that warned of communism as a "mortal threat to American liberty," and the AP described the address as veering into darkly political rhetoric to usher in America 250.
The DW reported Trump used Independence Day to warn of "communism is a mortal threat to American liberty" and called it a greater danger than World War I, World War II, Pearl Harbor or 9/11.
In New York City, Mayor Zohran Mamdani, a democratic socialist, delivered an address that cast America as a nation of contradictions, and the AP said Mamdani did not mention Trump by name while parts of his speech appeared aimed at the president’s divisive rhetoric.
The AP also tied the holiday’s political tone to the broader moment, noting that the anniversary came as a brutal heat wave gripped the eastern portion of the country and officials urged people to stay hydrated and take air-conditioned breaks.
In Washington, D.C., the Great American State Fair shut down in the early afternoon before reopening at 5 p.m., and an Independence Day parade scheduled for Saturday in Washington was cancelled.
What’s at risk next
With July 4 celebrations continuing Saturday afternoon and evening, ABC News said more than 75 million people were in the threat zone for severe storms, stretching across parts of the Plains into the Northeast, and it warned that fireworks could be impacted in New York City and surrounding areas.

ABC News reported that severe thunderstorm watches expanded and would remain in effect until 8 p.m. ET for the Chicago area and until 10 p.m. ET for parts of the mid-Atlantic including D.C., Baltimore and Richmond, Virginia, while a watch for Philadelphia into New Jersey and New York City was set to remain in effect until 11 p.m. ET.
The Times of India said the heatwave was expected to ease after the holiday weekend but warned that severe storms could pose an additional threat to Independence Day celebrations across parts of the eastern United States.
In Washington, D.C., the Great American State Fair temporarily closed as temperatures reached over 39 degrees Celsius (102 degrees Fahrenheit) in parts of the capital, and Al Jazeera reported that the Salute to Independence Semiquincentennial Parade in Philadelphia was cancelled after officials announced the heat-related risks.
Beyond weather and power, the AP said the holiday included a Capitol Fourth concert that opened its gates a little later than normal but moved forward with appearances from Patti LaBelle, Trace Adkins, members of the Artemis II space mission and fireworks over George Washington’s Mount Vernon, while Trump planned another speech at the National Mall before a historically massive fireworks show.
