PULGA, CALIFORNIA, JULY 15

A blaze that erupted near the flashpoint of the deadliest wildfire in recent U.S. history was heading away from homes on Thursday but survivors of the 2018 blaze worried that history could repeat itself.

The Dixie Fire had burned a couple of square miles of brush and timber near the Feather River Canyon area of Butte County and moved into national forest land in neighboring Plumas County.

There was zero containment and officials said people in the tiny, remote communities of Pulga and east Concow should prepare to leave at a moment's notice.

Flames raced along steep and hard-to-reach terrain about 10 miles (16 kilometers) from Paradise, the foothill town that was virtually incinerated by the Camp Fire that killed 85 people.

Larry Peterson, whose home in neighboring Magalia survived the previous blaze, said some of his neighbors were getting their belongings together in case they had to flee.

'Anytime you've got a fire after what we went through, and another one is coming up, you've got to be concerned,' he told KHSL-TV.

Other locals stocked up on water and other items.

'We pretty much left with our clothes on our backs' during the previous fire, said Jennifer Younie of Paradise. 'So this time we are looking to be more prepared and more vigilant.'

Joyce Mclean's home burned last time but she has rebuilt it and will again if necessary, she told the station.

'We just take each day as it comes and if it happens, it happens,' Mclean said. 'There's not much that we can do about it.'

Ironically, the blackened scar of the previous blaze was standing between the fire and homes.

'Everything's pretty much burned between them and the fire,' Butte County Supervisor Bill Connelly told the Sacramento Bee. 'Some bushes and grass have grown back, but it's probably not a direct threat at this time.'

The blaze is just one of nearly 70 active wildfires that have destroyed homes and burned through about 1,562 square miles (4,047 square kilometers) - a combined area larger than Rhode Island - in a dozen mostly Western states, according to the National Interagency Fire Center.

In southern Oregon the Bootleg Fire, the largest wildfire currently burning in the U.S., had torched an area larger than New York City and destroyed 20 houses. It threatened 2,000 structures in an area just north of California that's been gripped by a historic drought.

Tim and Dee McCarley could see trees exploding into flames in their rearview mirror as they fled the fire last week at the last minute. They had put off their departure to pack more belongings and search for their missing cat.

'The sheriff's department had been there and they said, 'If you don't get out of here now, then you are going to die,'' said Tim McCarley, 67, as he, his wife and stepson rested Wednesday at a shelter at the Klamath County Fairgrounds.

'We were running around like a chicken with its head cut off, throwing stuff into the car. Then we say, 'Okay, that's it ... we got to go.'

Tim McCarley was allowed to return briefly after the fire had passed over their rural community northwest of Bly. He found his home still standing and their cat inside unharmed. But the flames had crept within 5 feet (1.5 meters) of their house, the heat melting their trailer and storage units until they looked 'like a melted beer can,' he told The Associated Press in a phone interview.

The National Weather Service tweeted late Wednesday that a 'terrifying' satellite image showed gigantic clouds fueled by smoke and hot air had formed over the fire - a sign that the blaze was so intense it was creating its own weather, with erratic winds and the potential for fire-generated lightning.

'Please send positive thoughts and well wishes to the firefighters. ... It's a tough time for them right now,' the tweet read.

Extremely dry conditions and heat waves tied to climate change have swept the region, making wildfires harder to fight. Climate change has made the American West much warmer and drier in the past 30 years and will continue to make weather more extreme and wildfires more frequent and destructive.

An extreme heat wave late last month sucked vegetation dry in the Pacific Northwest, where firefighters say they are facing conditions more typical of late summer or fall than early July. The Northwest Interagency Coordination Center moved the region up to the highest alert level Wednesday as dry gusts were expected in some areas and new fires popped up.

In Washington, firefighters braced for the arrival of strong winds that could fan the flames of existing wildfires. The National Weather Service issued a red flag warning for much of eastern Washington beginning Wednesday afternoon and ending Thursday evening.

A fire in Chelan County in central Washington was threatening 1,500 homes along with orchards and a power station, authorities said. Mandatory evacuations were in effect. The Sheriff's Office said detectives and county and federal fire investigators served a search warrant at a home believed to be the place where the fire started but the news release didn't provide any other details.

In north-central Washington, about 200 people in the town of Nespelem on Colville tribal land were evacuated Monday night as the largest of five wildfires caused by dozens of lightning strikes tore through grass, sagebrush and timber.

Seven homes burned, but four were vacant.

That fire grew Wednesday but so did containment and it was now 20% surrounded.
