Major July 4th parade canceled due to extreme heat as temps soar over 100 degrees
Key Points:
- A dangerous multi-day heat wave is affecting the eastern US, breaking temperature records and causing extreme heat indices above 110 degrees in major cities like DC, Philadelphia, New York City, and Boston ahead of the Fourth of July holiday.
- Philadelphia canceled its Independence Day parade due to extreme heat, while DC’s Capitol Fourth concert will proceed with strong advisories for attendees to stay hydrated.
- Climate scientists attribute the intensity of this heat wave largely to human-caused climate change, with fossil fuel pollution making such extreme heat and humidity virtually impossible in the past.
- The heat wave is straining the electric grid, prompting energy officials to ask large power users like data centers to switch to backup power and utilities to reduce voltage or limit power use to prevent outages.
- Cities across the region have opened cooling centers, hydration stations, and emergency resources, while some events have been moved indoors or canceled to protect public health during the extreme heat conditions.
