GREENVILLE, Aug 9 (Reuters) - The monstrous Dixie Fire in northern California has grown to become the second-largest wildfire in state history, authorities said on Sunday (Aug 8), with three people reported missing and thousands fleeing the advancing flames.

As of Sunday, the fire had destroyed 463,477 acres, up from the previous day's 447,723 acres. It now covers an area larger than Los Angeles.

The Dixie blaze is the largest active wildfire in the United States, but one of only 11 major wildfires in California.

Over the weekend, it surpassed the 2018 Mendocino Complex Fire to make it the second-worst fire in state history.

"It was like driving out of a war zone that you see in a movie," Tami Kugler told AFP, sitting beside her tent at an evacuation station after fleeing the historic town of Greenville before it burned down.

"My neighbourhood is gone - I mean gone, gone. Everybody I care and love about that's in that neighbourhood, their homes are gone," she said, adding: "I didn't have insurance."

On Saturday, Governor Gavin Newsom visited the charred remains of Greenville, expressing his "deep gratitude" to the teams fighting the flames.

He said authorities had to devote more resources to managing forests and preventing fires.

But he added that "the dries are getting a lot drier, it is hotter than it has ever been ... we need to acknowledge just straight up these are climate-induced wildfires".

Climate change amplifies droughts, creating ideal conditions for wildfires to spread out of control and inflict unprecedented material and environmental damage.

The Dixie blaze, which on Saturday left three firefighters injured, remained 21 per cent contained Sunday, unchanged from the day before, the CalFire website reported.

Crews estimate the fire, which began Jul 13, will not finally be extinguished for two weeks.
