UPDATE (2:15 PM EASTERN):
Officials have confirmed that five people were found dead in vehicles that have been destroyed by wildfires in Northern California. This is developing information and will be updated.
A series of fast-moving wildfires is racing Friday up and down California, destroying thousands of structures and forcing thousands of residents to evacuate through flame-lined streets.
Two fires are just miles from the bar where 12 people were killed in a mass shooting in Southern California's Thousand Oaks, and a voluntary evacuation advisory was issued for part of Malibu, a seaside city popular with celebrities.
A blaze in Northern California sent terrified residents running for their lives as it closed in and destroyed parts of the town of Paradise, near Chico.
Some people have died as a result of the fires, but "we really can't put a number on it quite yet," state Office of Emergency Services Director Mark Ghilarducci said Friday.
Fanned by high winds and fueled by low humidity and dry vegetation, the fires spread rapidly Thursday and overnight into Friday. The threat continues Friday morning, with millions of Californians under "red flag" warnings portending windy, arid and warm conditions that pose extreme fire risks.
Here's what we know about the trio of fires:
Camp Fire: People flee 'carrying their babies and kids'
In Northern California, Tanah Clunies-Ross woke up in the dark Thursday to what sounded like lumps of coal raining down on her home. Within minutes, her family and thousands of people were racing to escape the raging flames of the Camp Fire.
"The smell of the smoke and realizing the smoke was a lot closer than I thought and then seeing flames up to my knees. ... I lost it," she said.
Her family was among at least 40,000 residents forced to evacuate in Butte County after the fire broke out early Thursday, "growing uncontrollably" at a rate of about 80 football fields per minute.
So far, it has burned at least 70,000 acres injured firefighters and residents and destroyed parts of Paradise, a town of 26,000 people roughly 80 miles north of Sacramento.
Friday morning the fire was burning to the outer edges of Chico, a city of 93,000 people about a 90-mile drive north of Sacramento. Area hospitals have evacuated and all of Butte County schools are closed Friday.
Whitney Vaughan described a scene of panic and terror as she recalled her narrow escape from her Paradise home on Thursday morning.
Vaughan and her husband had just fled their home as flames rushed them. She saw a man "sprinting past our house carrying a little baby, running as fast as he could."
They drove away but got eventually got caught in traffic. Flames were inches away, smoke was thick, cars weren't moving and people were panicking. Some people left their cars there "and took off running, carrying their babies and kids."
She cried as she recorded video of the terrifying scene, which she posted to Facebook. She and her husband eventually were able to drive away safely.
"We thought the fire was going to kill us," she told CNN.
The full extent of the destruction is still unknown, but authorities believe up to 1,000 buildings have been destroyed -- most of those in Paradise, a California Department of Forestry and Fire Protection (Cal Fire) spokesman said.
Multiple injuries have been reported by both civilians and firefighters, Cal Fire spokesman John Gaddie said. The extent of their injuries is unknown.
In Paradise on Friday morning, the town's main road was littered with downed trees and power lines. Much of the brush and grasses were blackened along the valleys, and many trees were still burning, a CNN crew there observed.
Late Thursday, more than 2,200 firefighters were battling the flames and the fire remains uncontained, according to Cal Fire.
Gov.-elect Gavin Newsom declared a state of emergency in the area and has requested federal funds to help those impacted by wildfires in the state. Newsom is serving as acting governor while Gov. Jerry Brown is traveling out of state.
Authorities fear the fire, fueled by strong winds, could reach Chico -- a city of 90,000 people where many Butte County families already have evacuated to shelters.
Woolsey Fire: Thousands of homes evacuated, Malibu area threatened
In Southern California, strong Santa Ana winds were fanning two fires, including the Woolsey Fire, which by Friday morning had burned across US 101 and was heading in the direction of Malibu.
The Woosley Fire exploded from 2,000 acres to 8,000 in Los Angeles and Ventura counties in a matter of hours Thursday night into Friday.
At least 75,000 homes in Ventura and Los Angeles counties are under evacuation orders, and some structures have already been destroyed, officials said.
The fire had crossed US 101 a few miles east of Thousand Oaks -- the site of Wednesday night's bar shooting massacre -- and was headed south to the Pacific coast, in the direction of Malibu Creek State Park and Malibu city, the Los Angeles County Fire Department said.
Mandatory evacuations were ordered for an area between US 101 and just north of Malibu.
And in part of Malibu itself -- a city of about 12,000 people known for beachside homes owned by celebrities and millionaires -- a voluntary evacuation advisory was issued Friday morning.
"Please, please, please if you are asked to voluntarily leave the area, please do," Ventura County fire Capt. Scott Dettore told CNN affiliate KTLA on Friday morning. "Make sure your stuff is packed and ready. Please leave the area."
Pepperdine University on Friday closed its Malibu and Calabasas campuses because of the approaching blaze.
In Malibu, journalist Julie Ellerton said she was calmly packing Friday morning after staying up all night.
Ellerton, in an email to CNN, said it was strange to go from covering events related to Wednesday's shooting "to looking up in the afternoon and seeing plumes of smoke."
"My heart's still with those suffering the loss of their children, their husband and their dad. I can't think anything matters more -- packing 'items' seems strange. The smoke just seems surreal," she wrote.
In Hidden Hills, just north of Calabasas, Adrienne Janic gave her home over to firefighters late Thursday to use as a command center. Her deck provided a strong vantage point to monitor the spread of the fire.
By 1 a.m. (4 a.m. ET), more firefighters arrived as the flames closed in on Janic's street
"While a lot of my yard and neighbors' yards burned, the firefighters saved our homes," Janic tweeted just after 2 a.m. (5 a.m. ET) Friday. "We are still not out of the woods yet."
Christy Dawn Little abandoned her Oak Park home, northeast of Thousand Oaks, around 11 p.m. PT.
"I had to work this evening, and ran out when I realized how close it was," Little told CNN. "We have found a safe hotel ... (in) Los Angeles."
Video of her drive out of town shows the fire emitting an orange-red glow in the distance in the nighttime sky.
Hill Fire: RVs, outbuildings burned
The Hill Fire is the other fire burning near the site of this week's mass shooting in Thousand Oaks.
The fire started Thursday afternoon and spread quickly to cover about 6,000 acres, fire officials said. On Friday, part of it was burning into the footprint of a 2013 wildfire, which could slow its spread, Ventura County Fire Chief Mark Lorenzen said.
Residents posted on social media to share their views of the flames nearly consuming the hillside in the Newbury Park area of western Thousand Oaks.
While no homes or businesses have been lost due to the fast-moving blaze, a number of RVs and outbuildings have been burned and a firefighter suffered a minor injury, authorities said.
Howling Santa Ana winds were driving the Woolsey and Hill fires. The Santa Anas are strong, dry winds that high-pressure systems push from east to west, from the mountains and desert areas down into the Los Angeles area.
Wind gusts of up to 77 mph were reported in Los Angeles County on Friday morning.
Winds were expected to weaken Friday afternoon into Saturday. A second round of Santa Ana winds is forecast to whip the area Sunday through Tuesday, though it may be weaker than Friday's.
