Newsweek -  National Weather Service meteorologists say that people in four states should change their drinking water habits as excessive heat grips the U.S. Southwest on Tuesday. High temperatures began scorching the region last week, breaking daily records in multiple cities as temperatures climbed past 100 degrees Fahrenheit. The heat has lingered this week, with warnings in place across multiple NWS offices in California, Arizona, Utah and Nevada. An excessive heat warning is in place across each of the four states. There also is a heat advisory issued in central California. The high temperatures are prompting meteorologists to suggest people drink more fluids to stave off heat exhaustion or heatstroke, which can be fatal. Some of the worst heat is expected in the Phoenix, Arizona, region, where dangerously hot conditions will occur with temperatures forecast to be between 106 and 115 degrees Fahrenheit.

"Drink plenty of fluids, stay in an air-conditioned room, stay out of the sun, and check up on relatives and neighbors," the warning read. "Do not leave young children and pets in unattended vehicles. Car interiors will reach lethal temperatures in a matter of minutes."
