(CNN) The Thomas Fire is now the largest wildfire in California's modern history after torching 273,400 acres.

The blaze has surpassed the size of the Cedar Fire near San Diego, which destroyed 273,246 acres in 2003, according to the California Department of Forestry and Fire Protection, also known as Cal Fire.

Cal Fire has compiled a list of the biggest fires since 1932.

The Thomas Fire has devastated swaths of Southern California since it began on December 4 fueled by strong Santa Ana winds in Ventura County. It remains as the third-most destructive in structure losses, with 1,063 buildings burned, according to Cal Fire.

As of Friday night, the blaze was only 65% contained. Firefighters have been battling the flames for nearly three weeks in Ventura and Santa Barbara counties and are expected to continue working around the clock until January 7, fire officials said.
