LNU Lightning Complex Fire grows to 347,630 acres, one of the largest wildfires in California history

The wildfire has reached 347,630 acres and is burning in Napa, Sonoma, Solano, Yolo and Lake counties.

CALIFORNIA, USA — 7:30 p.m. update:

Even as firefighters make gains on containing the LNU Lightning Complex Fire, they still expect more growth throughout the operation.

The fire continues to challenge crews with short and long range spotting as it runs in multiple directions, impacting multiple communities. 

The fire has grown to 347,640 acres and is 21% contained.  871 structures have been destroyed.

2:30 p.m. update: Cal Fire announces evacuation orders downgraded to evacuation warnings and lifted for multiple areas of Sonoma County.

All of the areas with evacuations lifted are on Cal Fire LNU's twitter page.

11:25 a.m. update: Cal Fire officials are taking precautions as they expect more fires to pop up tonight. A red flag warning was issued on Saturday for the northern half of California due to potential lightning strikes and erratic winds. Crews are preparing to stop lightning-caused fires as they happen tonight.

Officials also said evacuation orders should be taken seriously and that they are given because they are "based on an immediate threat to life."

They told residents in the fire areas to listen for a siren to signal evacuations. Evacuation sirens are in all emergency vehicles and are prepared to go off when they are needed. Officials played the siren and described it as a "high-low" sound.

"If you hear the high-low, it is time to go," said an official.

An evacuation order has been issued for Lake County, according to Cal Fire. The Lake County Sheriff's Office has issued an evacuation order for all residents living south of Morgan Valley Road, west of the mandatory evacuation border line at Sky High Ridge Road to Highway 29 and Highway 53 in Lower Lake.

12:30 p.m. update:

Fire crews in California are making slow progress in their battle against some of the largest wildfires in state history thanks to favorable weather overnight and help from other states. Firefighters and aircraft from 10 states are arriving in California to help weary crews fighting the blazes that have killed six people and burned hundreds of homes. Some 560 wildfires are burning throughout the state. The most damaging are three clusters of blazes in the San Francisco Bay Area and nearby wine country. Firefighters hope to make more progress before Sunday brings the threat of lightning strikes that could spark new blazes. 

During a press conference Jeremy Rahn, public information officer for the LNU Fire, said over 13,700 firefighters are working on nearly two dozen major fires and lightning complexes throughout California. 

"Since the lightning siege that started August 15, nearly 12,000 lightning strikes, with over 100 of them occurring yesterday. During this time period there have been more than 585 new wildfires, which have burned nearly 1 million acres," he said.

The National Guard has been activated and is providing helicopter support and a dozen 20-person crews, according to Rahn. The federal military is supporting the effort with several C-130 air crafts equipped with modular fire systems, he said.

"45 minutes maximum an hour, we were pulling out of here with whatever we could get out of the safe, whatever we could get out of my office, whatever we have personal items. I lost stuff that was on the walls from my great grandfather.”

The Solano County Sheriff's Office says some evacuations from the LNU Lightning Complex Fires could be lifted this afternoon. In a Facebook video, the sheriff's office said it is meeting now with Cal Fire to discuss plans.

Solano County plans to lift evacuations in phases, meaning not everyone will be allowed back at once. Roadblocks will be set up in the areas and people will need proof of their residency to get in.

"You'll see a lot of fire equipment. You'll see a lot of law enforcement presence," said Lt. Jackson Harris with the Solano County Sheriff's Office. "We are not planning on easing up on that."

When people are allowed back into the evacuated areas, they will still be under an evacuation advisory. "That means, stay prepared to leave at a moment's notice," said Harris. He also suggests that for people who might need more time to evacuate, it would be safer to stay out.

Firefighters have managed to contain part of the fire near Vacaville. The small section of containment is along the southern edge near I-80 approaching Fairfield and the Gordon Valley area.

Original Story

Cal Fire is warning it expects significant fire growth as firefighters battle the deadly LNU Lightning Complex Fires.

The fires have now grown to 215,000 acres across five counties in Northern California and there is no containment. The fire has destroyed 480 buildings and damaged 125 more. More than 30,000 buildings are still threatened by the fire.

Four people are confirmed to have died. Little is known about the victims, but CAL FIRE officials say three victims were found in Napa County and one was found in Solano County. Four other civilians were injured, officials said.

The LNU Lightning Complex Fires include several fires including Hennessey, Gamble, 15-10, Spanish, Markley, 13-4 and 11-16. The fires are burning in parts of Napa County, Sonoma County, Solano County, Yolo County and Lake County.

Vacaville launched a new website that lets residents determine if their home is in an evacuation zone. Vacaville police did warn of delays at times yesterday as tens of thousands of users tried to access the resource.

After you type in your address, you'll either receive a message saying "Boundary Status: ACTIVE" which means you are in an evacuation area or "No results found" which means you are not in an active evacuation area.  

Cal Fire posted evacuation information on Twitter, here and here.

Vacaville Fire Chief Kris Concepcion is urging people to take precautions to protect themselves from the smoke and bad air quality.

"It's very hard to breathe in this kind of environment. So, what you can do is limit the time you are outdoors to what is just necessary, stay inside," said Chief Concepcion. " And if you have a damper on your air-handling system, like you air conditioner, make sure that's closed so the ash can't get in and get inside your house."
