The Thomas Fire, which continues burning in Ventura County and is moving toward Santa Barbara, has increased to 115,000 acres, or about 180 square miles, officials announced Thursday evening.
The blaze, which began in Santa Paula area on Monday, is 5 percent contained.
Nearly 440 structures have been destroyed in the fire, officials estimated, but explained that the number is preliminary.
In Ventura, 427 structures were destroyed, while 85 were damaged. In unincorporated areas of the county, 12 structures were destroyed.
Thousands of residents throughout the county remain evacuated, though officials are in the planning stages of repopulating areas in Ventura.
New evacuation orders were in place in Fillmore Thursday night, as the blaze threatens homes in that area of the county.
Tim Chavez, a fire behavior analyst at Cal Fire explained that while Santa Ana conditions are expected to weaken on Friday, that can actually be more dangerous for firefighters because it is difficult to know which direction the fire is going in.
“Crews are going to (need to) be very careful on their positions when those transitions happen,” Chavez said.
Santa Barbara Sheriff Bill Brown urged residents who live at the county line with Ventura, along the coast and up to Summerland to be "ready to go at a moment's notice." While there are no evacuation notices in those areas yet, Brown said the Thomas Fire still poses "an extreme danger" and is "far from being extinguished.
"It could come toward Carpinteria, and if it does, we want people to be prepared to leave immediately," the sheriff said.
