Extreme heat grounds flights in Phoenix

Nearly 50 American Airlines flights out of Phoenix Sky Harbor International Airport were canceled on Tuesday as soaring temperatures are forcing planes to stay grounded.

Extreme heat affects a plane's ability to take off. In a statement provided to the Arizona Republic, the airline said that its American Eagle regional flights use the Bombardier CRJ aircraft, which has a maximum operating temperature of 118 degrees.

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.
