Plumes of smoke loom in the sky several miles away, seen behind a home in Thousand Oaks, Calif., as a wind-driven wildfire known as the Hill fire threatens the area late Thursday afternoon, November 4, 2018.
The Butte County Sheriff's Office issued evacuation orders and warnings for numerous fire zones in the area.
The Camp Fire started Thursday morning near Paradise, a town of around 27,000 some 90 miles north of Sacramento. By 2:00 p.m. local time, it had grown to 18,000 acres, according to Cal Fire.
"Pretty much the community of Paradise is destroyed, it's that kind of devastation", said Cal Fire Capt. Scott McLean late tonight.
Bernacett says the fire overtook the Feather River Hospital, about two miles (three kilometers) east of the mobile home park.
"Luckily, the fire broke out early enough that there were only a few students there and we had a plan".
The massive plume from the Camp Fire, burning in the Feather River Canyon near Paradise, Calif., wafts over the Sacramento Valley as seen from Chico, Calif., on Thursday, Nov. 8, 2018.
Video footage taken by ABC Redding affiliate KRCR showed the hospital surrounded by thick smoke as the fire illuminated the darkened sky in the background. "Once it got going it picked up very rapidly".
"This fire is very risky, please evacuate if asked to do so!" the California Department of Forestry and Fire Protection (Cal Fire) tweeted.
Officials were sending as many firefighters as they could, Cal Fire spokesman Rick Carhart said. "We tried to get all the nondigital things that we could - you know, stuff that couldn't be replaced", Peete said. "All patients are being transported to surrounding area hospitals", a statement said.
In Chico, west of the fire, resident Tina Greer said the care home where her disabled son lives with five other patients was evacuating.
Four of the hospital's employees were briefly trapped in the basement and rescued by California Highway Patrol officers, Kinney said.
"Right now, Mother Nature is in charge", Bennett said.
A Red Flag Warning is in place through Friday morning in the Butte County area, and winds are expected to gust at speeds as high as 40 miles per hour overnight, according to the National Weathers Service.
