Firefighters on the ground and in the air are battling a fast-moving brush fire raging across 45,000 acres in Ventura County, destroying 150 structures and forcing 27,000 people to flee their homes, fire officials said Tuesday morning.
Gov. Jerry Brown declared a state of emergency in Ventura County because of the fire.
Officials had earlier said a person's death was associated with the fire, but Ventura County spokesman Bill Nash said early Tuesday that death was a family pet, not a person. One firefighter was injured, but details on his condition weren't immediately available.
The fire, dubbed the Thomas fire, was first burning just south of Thomas Aquinas College. The college issued a fire alert Monday around 8 p.m. and evacuated all students to nearby homes as a precaution.
"The fire growth is just absolutely exponential," Ventura County Fire Chief Mark Lorenzen said. "All that firefighters can do when we have winds like this is get out ahead, evacuate people, and protect structures."
More than 8,000 homes were evacuated and 20,000 people remained without power Tuesday. That figure was down from 200,000 customers who were in the dark Monday night because of transmission line problems associated with the fire.
The fire spread extremely quickly. The Ventura County Fire Department tweeted that the fire was moving fast and was burning in steep terrain with 25 to 30 mph winds.
At least 150 structures were damaged, according to the fire department. One of those was the Vista del Mar Hospital, an 83-bed mental health facility at 801 Seneca St. All patients were evacuated safely, but the majority of buildings were left to be nothing but smoking husks. The apartments on the skirts of the facility had not yet been threatened by 6 a.m.
"Oh my god, just devastation for these people," said Leticia Broida, an employee. "The whole hospital is gone."

Mandatory evacuations were ordered for west Ventura shortly before 1 a.m., Tuesday. Multiple homes and buildings were reportedly burned in the area and palm trees were on flames behind Ventura City Hall.
Due to the intensity of the blaze, fire crews were reportedly having difficulties accessing the burned areas. Multiple agencies are responding to the fire.
