Amid sweltering heat, dozens of flights canceled in Phoenix

The summer average temperatures in Phoenix could be more like Kuwait City by the end of the century, making this now rare heat routine.

Each aircraft manufacturer sets its own parameters for operating temperatures, Feinstein said. As temperatures increase, a plane needs more speed to lift off and certain runways might not be long enough to allow for such speed to be reached, according to the Arizona Republic.

The forecast called for a high of 120 degrees (49 degrees Celsius) in Phoenix, 119 in Palm Springs, California, and 126 in Death Valley.

American Airlines flights from Phoenix to cities including Boston, Chicago, and Denver use aircrafts that can operate at higher temperatures and will be unaffected by the cancellations, the Phoenix New Times reported.

Dozens of flights were cancelled Tuesday in Phoenix as extreme heat swept over the region, prompting officials to deem it too hot for some planes to fly. Beneath the dome, sinking air is causing temperatures to soar well over 110 degrees in many areas.

Larger jets, such as those manufactured by Airbus AIR, -0.59% and Boeing BA, -0.38%, aren't expected to be affected by this week's heat.

Phoenix is expected to beat its all-time highest temperature today.

"Down here, it's hot", Guadalupe said. The temperature in Phoenix, Arizona also touched almost 50 degrees Celsius, . or just 120 degrees Fahrenheit, one of the highest temperatures ever recorded in the city.

"I have 13 different boarding passes just from yesterday in my backpack", says one traveler who was rebooked several times and had to stay overnight because of heat cancelations.

Arizona has been experiencing extreme heat lately, even when compared to usual weather conditions in the state in late June. And temperatures remained high even as night fell: at 9:30 p.m. Monday, temperatures were still topping 109 degrees Fahrenheit. The temperature in Tucson, Ariz., was 116 degrees, one degree short of its historic record.

Phoenix has hit 120 only three times in recorded history.

Excessive heat warnings have been issued for inland California, southern Nevada, and parts of southwest Arizona through Friday.

Authorities warned about the dangers of heat illness and urged people to be vigilant about not leaving pets or children inside a auto for any time at all.

Authorities in Phoenix are trying to keep about 350 jail inmates housed in outdoor tents cool despite triple-digit heat.
