A local fire official said there were multiple injuries among civilians and firefighters.
"Things started exploding", Oviedo said.
"It's a very risky and very serious situation", Butte County Sheriff Kory Honea said. He was wrong. It was the flush of the Camp Fire around the town that made him panic: "I was waving down people just anyone on the road just help me because i didn't have a vehicle or nothing".
With limited escape routes from the town, which is built on a ridge, traffic accidents turned roads into gridlock, with residents forced to abandon vehicles and run from the flames carrying children and pets, officials said.
"We're getting them on other vehicles with room. We're doing everything we can to get people out of the affected areas". "The message I want to get out is if you can evacuate, you need to evacuate", Honea said. Paradise itself is around 70 miles south of Redding, where the Carr Fire killed eight people and destroyed more than 1,000 homes in July.
The Camp Fire has scorched over 28 square miles in Butte County, which is about 90 miles north of Sacramento, according to Cal Fire. Dry, windy conditions are making it hard to contain the fire.

The Adventist Health Feather River Hospital in Paradise evacuated all its patients and staff, given its close proximity to the fire, and transported them safely to hospitals in neighboring towns, Jill Kinney, an Adventist Health spokeswoman told the Associated Press.
Four of the hospital's employees were briefly trapped in the basement and rescued by California Highway Patrol officers, Kinney said.
Shari Bernacett said her husband tried to get people to leave the Paradise mobile home park they manage and had minutes to evacuate. He "knocked on doors, yelled and screamed" to alert as many residents as possible, Bernacett said.
