Meanwhile, Phoenix is expecting to hit a high of 122 degrees on Tuesday.

Millions of Americans are under excessive heat warnings from California to Nevada. The hot temperatures are knocking out power and buckling roads. Additionally, U.S. Border Patrol is stepping up warnings to migrants attempting to cross into the U.S. by the Sonoran Desert.

That almost seems cool in comparison to what residents in Death Valley, California will feel, as the temperature is expected to rise to a whopping 127 degrees.
