A severe heat wave has broken over 280 heat records across the U.S., driven by a 'heat dome' that has caused dangerous conditions affecting nearly 130 million people, with continued high temperatures expected.
A NASA map using satellite images and the Goddard Earth Observing System model reveals extreme heat across the U.S. on July 10, 2024, with temperatures exceeding 104 degrees Fahrenheit in many areas. The Southwest experienced the most intense heat, with Las Vegas setting a record of 118 degrees. Death Valley saw a high of 129 degrees, leading to a fatality and multiple hospitalizations. The heat wave has also affected the East Coast, with New York City and Washington, D.C. experiencing record temperatures. Excessive heat warnings remain in effect for several regions.
