A combination of wildfires raging north of San Francisco, which already has consumed an area almost as big as Los Angeles, is now the largest fire in modern California history, authorities said Monday night.

The Mendocino Complex fire, which includes two blazes along the Mendocino National Forest, had chewed through more than 283,800 acres as of Monday night. The blaze is just 30 percent contained, Cal Fires Mendocino unit said.

We broke the record, Scott McLean, a deputy chief of Cal Fire, told the Los Angeles Times . Thats one of those records you dont want to see.

It is extremely fast, extremely aggressive, extremely dangerous, he said. Look how fast this Mendocino Complex went up in ranking. That doesnt happen. That just doesnt happen.

Last years Thomas fire, which consumed 281,000 acres in Santa Barbara and Ventura counties, is now the states second-largest on record. The Cedar fire in 2003, now the third-largest, devoured 273,246 acres in San Diego County, according to Cal Fire records. The city of Los Angeles, by comparison , is about 300,000 acres.

Firefighters predict theyll fully contain the Mendocino Complex fire by Aug. 15.
