Death Valley recorded a scorching 130 degrees (54.4 degrees Celsius) Sunday, which if the sensors and other conditions check out, would be the hottest Earth has been in more than 89 years and the third-warmest ever measured.
Sunday's temperature would beat marks of 129 (53.9 Celsius) recorded three times in recent years, he said.
The 130-mark capped a week and an ongoing summer of very strange weather, said Deke Arndt, director of the National Weather Service's Center for Weather and Climate and former chairman of the U.S. national weather extremes committee.
Death Valley's National Park's 130-degree temperature was recorded at 3:41 p.m. at Furnace Creek near the park's visitor center.
It's the same area that holds the world record for highest temperature ever recorded 134 degrees (56.67 Celsius) set on July 10, 1913, although that record remains in dispute.
