US braces for second day of scorching weekend temperatures
An oppressive heat wave stretching from the Midwestern plains to the Atlantic coast had nearly 150 million people struggling to stay cool amid stifling temperatures Saturday.
"The temperatures we're seeing in our city today and tomorrow could be the highest we've seen in years. Take it seriously," New York Mayor Bill de Blasio said on Twitter.
The heat was expected to continue through late Sunday as a high-pressure system off the Atlantic coast ushered in steamy, subtropical air.
"Dangerously hot conditions will continue through Sunday," the National Weather Service (NWS) warned for the Washington and Baltimore area, where forecasters predicted high temperatures ranging from 95 to 100 degrees for a second day.
"High temperatures and humidity could quickly cause heat stress or heat stroke if precautions are not taken," the NWS added.
