Heat wave threatens Fourth of July celebrations and power grids

A severe heat wave swept across the eastern United States on Friday, bringing near‑record temperatures that threatened to disrupt July 4th celebrations, World Cup matches and the region’s power grids. Meteorological agencies reported that several states recorded temperatures in the upper 90s to low 100s Fahrenheit, with some heat indices surpassing 120 degrees in parts of the Midwest and Southeast.

The sweltering conditions prompted the National Weather Service to issue heat advisories and urged residents to stay hydrated and avoid outdoor activities during peak heat. Major cities planned for Independence Day fireworks and parades were forced to postpone or cancel events, while the U.S. Soccer Federation announced that the upcoming World Cup qualifiers would be rescheduled due to the extreme heat. Power utilities reported increased demand and several substations were operating at capacity, raising concerns about potential outages.

Officials are monitoring the situation closely, with the Department of Energy and regional grid operators coordinating to maintain supply stability. Residents are encouraged to follow official guidance and to seek air‑conditioned shelters if necessary, as the heat wave is expected to persist for several more days.
