Some 195 million Americans — out of a population of more than 330 million — are facing dangerously high temperatures as much of the mainland U.S. is under excessive heat advisories beginning Thursday and expected to last until the weekend.
Before relief arrives, temperatures will reach levels that feel hotter than 100 degrees Fahrenheit, the National Weather Service warns.
Earlier this summer, a heat wave around the Portland, Ore., area and in Canada was blamed for the death of hundreds of people. This time around the oppressive heat will not only exacerbate drought conditions and wildfires in the West but also will make for dangerous conditions on the East Coast.
The National Weather Service predicts the Interstate 95 corridor in the East could reach 100 F Thursday afternoon. Oppressive heat indexes, a measure of how hot it really feels outside, are expected to range between 105 to 110 degrees Fahrenheit.
