Extreme heat has significantly impacted July Fourth celebrations, particularly in Washington D.C., where temperatures reached a record 102 degrees Fahrenheit on Saturday, making it the hottest July Fourth ever for the city and surpassing the 1919 record of 100 degrees. The heat index was expected to hit between 110 and 115 degrees Fahrenheit. This led to the cancellation of America's National Independence Day Parade on Friday evening due to safety concerns for participants and spectators. The Great American State Fair and FIFA Fan Zone on the National Mall also delayed its opening by two hours on Saturday.
The widespread extreme heat is fueling severe weather across a large portion of the country, with over 75 million people in the threat zone for severe storms stretching from the Plains to the Northeast. The primary hazard is damaging wind gusts, with a level 3 of 5 risk for parts of the Mid-Atlantic, including Washington D.C. and Baltimore, as well as parts of Kansas and Oklahoma. New York City's fireworks could be affected, with thunderstorm activity expected between 8 to 10 p.m. ET. The severe weather threat is expected to continue into Sunday for the Mid-Atlantic region.
The heat wave and severe weather have also caused significant power outages, with nearly 779,000 homes across multiple states in the Midwest and Northeast experiencing blackouts. Amtrak also canceled several trains (88, 10, 94, and 695) due to temperature-related conditions, expressing apologies for the inconvenience. Organizers of various events, including Freedom 250, have coordinated with authorities like the National Park Service, U.S. Park Police, and FEMA to provide cooling resources, water stations, and medical support.
