More than 95 million people from Southern California to western Pennsylvania and as far south as Florida are already under an excessive heat warning or heat advisory
Heat-related warnings and advisories were in effect Wednesday for nearly a third of the U.S. population, mostly in the Midwest and Southeast, the National Weather Service said, adding that it may take weeks to see relief.
More than 95 million people from Southern California to western Pennsylvania and as far south as Florida were under an excessive heat warning or heat advisory, meteorologists said. Residents should expect to see temperatures rise well into the 90s and 100s, with heat indexes — a measure of how hot it feels factoring in humidity and temperature — soaring in some locations into the triple digits.
