A severe heatwave is impacting several US cities, including New York, Philadelphia, and Washington D.C., with temperatures nearing 40°C (104°F). The extreme heat has caused widespread power outages, creating significant challenges for residents. Consequently, organizers have been forced to delay the start of Independence Day celebrations planned for July 4th. The heatwave is also impacting events related to the ongoing Women’s World Cup. Authorities are urging caution and advising citizens to take necessary precautions to avoid heatstroke and other heat-related illnesses. The unusual weather pattern is casting a shadow over the nation's 250th Independence Day anniversary.
