A severe and prolonged heatwave is set to escalate across a vast region of the United States this week, bringing with it blistering daytime temperatures, elevated humidity levels, and oppressive nighttime conditions, according to meteorologists.
As of Tuesday, approximately 120 million Americans are under extreme heat warnings as the nation approaches the Fourth of July holiday weekend, the National Weather Service (NWS) reported.
Meanwhile, much of Canada is also experiencing rising temperatures, with Ontario expecting highs of up to 37°C (99°F) starting Tuesday.
This comes on the heels of an unprecedented early summer heatwave that has affected several European nations, shattering temperature records across the continent.
The current heatwave is projected to impact a large swath of the country, extending from the East Coast to central regions.
By Thursday, around 250 million individuals will encounter some level of hazardous heat, according to weather experts.
The extreme temperatures, driven by a heat dome phenomenon, are predicted to peak in the Midwest and Mississippi Valley by Thursday before shifting eastward into the Ohio Valley and East Coast throughout the holiday weekend.
Temperatures are expected to range from 95°F to 105°F, with high humidity pushing the heat index to between 100°F and 115°F.
Records for daily temperatures are likely to be broken on Thursday and Friday, with some monthly and all-time highs also at risk.
Authorities are urging residents in affected areas to minimize outdoor activities, stay well-hydrated, and ensure access to air conditioning or cooling centers.
In New York City, Mayor Zohran Mamdani has activated a heat emergency plan, with hundreds of cooling centers scheduled to open on Wednesday.
Detroit is also responding to the extreme conditions, with temperatures potentially reaching 100°F, the city has opened a dozen air-conditioned recreation centers for residents seeking relief.
The intense weather could pose challenges for some World Cup matches, with heat indexes potentially exceeding safety thresholds established by the global players’ union, Fifpro.
Texas is expected to experience the hottest conditions, impacting fans traveling to and from air-conditioned stadiums in Houston and Arlington.
This situation may also affect the England vs. DR Congo match on Wednesday in Atlanta, Georgia.
In Philadelphia, parts of the FIFA World Cup Fan Festival will be relocated into cooled tents on Thursday and Friday to provide respite from the heat.
In Canada, high temperatures are anticipated to persist until Thursday, particularly in Ontario, where they could reach 37°C (99°F).
Toronto is scheduled to host a World Cup game on Thursday when temperatures are forecasted to hit 35°C (95°F).
