Heatwave Develops Across Eastern US
Ben Rich reports on a significant heatwave forming across the eastern United States, bringing intense heat and humidity.
A prolonged and hazardous heatwave is expected to strengthen over a wide area of the US this week, delivering scorching daytime temperatures, elevated humidity levels, and oppressive overnight warmth, according to forecasters.
Approximately 120 million people nationwide are under extreme heat warnings as of Tuesday, coinciding with the approach of the Fourth of July holiday weekend, the National Weather Service (NWS) announced.
Heatwave Extends into Canada
To the north, much of Canada is also experiencing a heatwave beginning Tuesday, with temperatures forecast to reach up to 37°C (99°F) in Ontario.
This heat event follows an unprecedented early summer heatwave in Europe, which affected multiple countries in recent days and resulted in broken temperature records across the continent.

Geographic Scope and Progression
The heatwave is predicted to impact a broad region of the United States, spanning from the East Coast to central parts of the country.
The extreme temperatures, driven by a heat dome, are expected to peak in the Midwest and Mississippi Valley through Thursday, the NWS forecasted. The heat will then shift eastward into the Ohio Valley and East Coast on Thursday and persist into the holiday weekend.
Temperatures ranging from 95°F to 105°F (35°C to 40.6°C), combined with high humidity, will produce heat index values between 100°F and 115°F (38°C to 46°C).
Daily temperature records are anticipated to be broken on Thursday and Friday, with the possibility of some monthly and all-time records being surpassed.
Public Safety Measures
Authorities are advising residents in affected areas to limit outdoor activities, maintain hydration, and ensure access to air conditioning or cooling centers.
New York City Mayor Zohran Mamdani has activated a heat emergency plan, with hundreds of cooling centers scheduled to open across the city starting Wednesday.
In Detroit, where temperatures may reach 100°F (38°C), a dozen recreation centers equipped with air conditioning have been opened for residents seeking relief from the heat.
Impact on World Cup Events
The intense heat may affect some World Cup matches, with heat indexes potentially exceeding thresholds deemed unsafe for play by the global players' union Fifpro.
The highest temperatures are expected in Texas, which could affect fans traveling to and from the air-conditioned stadiums in Houston and Arlington. Similarly, the England versus DR Congo match on Wednesday in Atlanta may experience hot and humid conditions outside the stadium.
Philadelphia is relocating portions of its FIFA World Cup Fan Festival into cooled tents on Thursday and Friday to mitigate heat exposure.
