In Oregon, the wildfires have burned almost 200,000 acres of land.
At least 10 people have been killed by the rampant blazes and many others are reported missing.
One child has died in Washington, where there were five large fires on Sunday.
In a statement on Friday, Washington Commissioner of Public Lands Hilary Franz said: “My heart breaks for the family of the child who perished in the Cold Springs fire.
“I am devastated. The DNR family is devastated. The pain that family is going through is unfathomable.”
