The fire, which was sparked by a car fire in the city of Kirkland, has charred more than 100,000 acres in three months and is the deadliest blaze in the United States in more than three decades.
The fire is the most powerful to hit the state in more a decade and has left at least 30,000 homes and businesses without power.
The governor, Cale Bynum, has declared a state of emergency and has ordered the state to begin rebuilding.
The mayor of Boise, Ada Mayor Tom Tingle, said he expected the fires to last until January, when they are expected to be extinguished.
“I’m optimistic that by then, the fires will be extinguished,” he said.
The city of Boise is the city in the heart of the state’s second-largest city, with a population of about 2.5 million.
It is located in an area with high concentrations of fossil fuel extraction, oil and gas extraction, and other industries.
With the help of the USGS, the Bureau of Land Management and the state of Idaho, the fire burned for more than two weeks, spreading across the state and into the mountains and plains.
The blaze was caused by an oil pipeline fire, with flames reaching 1,500 feet (305 metres) into the air and causing the city to lose a quarter of its residents.
In response, President Donald Trump, a Republican, signed an executive order calling for the federal government to immediately provide up to $1 billion in emergency aid to the city.
But Tingle said he did not expect the city’s population to be saved overnight.
He said that the federal aid would be given as soon as the city is able to get the necessary permits to get a large-scale restoration project under way.
“We need to make sure that all the permits get signed, so that this is a safe and efficient process,” he told CNN on Sunday.
Firefighters have worked through the night in a bid to put out the flames and are confident the fires could be extinguished in time for Christmas, Tingle told the local ABC station.
Tingle, who has led a campaign against the pipeline, said the flames were also “caused by oil, which is a very dirty fuel”.
“The pipeline was going to be in the water, so we need to get rid of that now,” he added.
Bynum said he was confident the state would get through the winter and was confident that the fires would not continue.
More to come.
