(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.

A deadly wildfire which has destroyed more than 700 homes in California is now the largest blaze in the state's recorded history.
The Thomas fire has burned more than 1000sq km - an area greater than New York City, Brussels and Paris combined.
The blaze broke out in Santa Paula in early December and has moved west towards the coast, one of several major fires in California in recent months.
Thousands of firefighters have been deployed to bring it under control.
Most of California's largest wildfires have been recorded this century. Scientists say the warming climate and spread of buildings into wilderness areas have contributed.
The Thomas fire slowly eclipsed previous record-setting blazes, finally overtaking the 2003 Cedar fire in San Diego County, which burned 273,246 acres.
It follows a series of deadly fires in the state's wine country in October that burned more than 10,000 homes and killed more than 40 people.
The Thomas fire has destroyed more than 1,000 buildings and claimed the life of one firefighter - Cory Iverson, a father of one from San Diego whose wife was expecting another child.
The blaze is now moving slower because of rain and less wind.

State fire agency Cal Fire says the Thomas blaze is now 65% contained and expected to continue to slow. Controlled burns by firefighters may cause some temporary expansion, it said.
Seven of California's 10 largest fires on record have occurred since 2000. Two were in the 1970s and the earliest was in 1932 - the Matilija fire which, like the Thomas fire, burned through Ventura County.
