Searing heat wave grills large parts of the US, causes deaths in the West and grips the East

After causing deaths and shattering records in the West over the weekend, a long-running heat wave will again grip the U.S. on Monday, with triple digit temperatures predicted for large parts of the East Coast. A visitor to Death Valley National Park has died from heat exposure and another person has been hospitalized as the temperature there reached 128 degrees this weekend. Officials say the two visitors were part of a group of six motorcyclists riding through the Badwater Basin area on Saturday. The park said in a statement Sunday that the other motorcyclist was taken to a Las Vegas hospital for severe heat illness. An excessive heat warning, the National Weather Service’s highest alert, was in effect for about 36 million people nationwide.
