SAN FRANCISCO: Firefighters struggled to contain an exploding Northern California wildfire under blazing temperatures as another heat wave hits the US West this weekend, prompting an excessive heat warning for inland and desert areas.

On Friday, Death Valley National Park in California recorded a staggering high of 130 degrees Fahrenheit (54 Celsius) and could reach the same high on Saturday. If verified, the 130-degree reading would be the hottest high recorded there since July 1913, when the same Furnace Creek desert area hit 134 F (57 C), considered the highest reliably measured temperature on Earth.
