Tens of millions swelter as heatwave blankets the central and eastern US | US weather
National Weather Service (NWS) published several extreme heat WARNINGS AND RECOMMENDATIONS As a dangerous and long high temperature and moisture blanket wave of most of the Middle and Eastern USA, the worst conditions are expected to continue in the middle of this week.
A few places recorded the hottest temperatures of the year at the weekend: Salt Lake City, Utah, hit 104F (40C) on Thursday, the first three -digit reading of 2025 and the city of Mitchell in South Dakota on Saturday and exceeded the previous daily record of 101F (38.3c). In some parts of Minnesota, Wyoming and Michigan, daily high records were broken.
Cities under active heat warnings include Chicago, Kansas City, St Louis, Detroit, Cincinnati, Pittsburgh, Philadelphia, Washington DC and New York. NWS classified some of its warnings as “excessive heat” warnings, the highest level due to the seriousness of the conditions.
Some cities, including Boston, New York, Philadelphia and Washington, may approach or exceed 100F (37.8c) during the summit of the heat wave. NWS said New York’s Central Park has not reached this level since July 18, 2012, and Philadelphia’s last hit in June 1994.
Moisture is also a factor, oppressive moisture levels use the “heat index” values-this is also a factor in moisture, to feel how warm it feels to a human-to the western western, large lakes, middle atlantic and northeast trilateral steps. In some parts of Middle USA, the heat index may rise up to 46C (115f).
In the meantime, at night at around 21C-27C in urban areas, it will provide little relief among the lowest levels, especially among vulnerable populations and increase the risk of heat-related disease.
In New York, authorities encourage residents to take precautions. The city’s Emergency Management Agency warned on Saturday, “This is the most deadly threat of air we have encountered in New York – Act this way” social media. “Do not wait until you feel the patient. Heat occurs. Compounds. Silently kills.”
Philadelphia’s Public Health Department announced A heat health emergency starting on Sunday noon.
Authorities call on the people to remain watery, limiting time outdoors, and to control others at risk as the elderly neighbors and heat wave continues.
