Millions of people across the eastern and central parts of the U.S. are trying to stay cool on Saturday, as a massive heat wave bakes the region.
The National Weather Service said temperatures were forecast to reach the mid- to upper 90s.
But with the humidity, the heat index could hit as high as 115 degrees in some areas.
The heat wave extends from Kansas to the Atlantic Coast and from South Carolina to Maine.
In Washington, D.C., residents and tourists tried to catch a breeze on the Potomac River.
Others sought to escape the scorching heat by heading to museums. In New York, where the heat index was 100 degrees and forecast to rise to 110, hundreds found refuge in a pool in Queens.
Meanwhile, in Philadelphia about 250 senior citizens returned home on Saturday, a day after their retirement community lost power, disabling their air conditioners.
Forecasters say the heat wave is expected to continue through Sunday with little overnight relief.
