The so-called Okanogan complex of wildfires in the north-central part of the state has already surpassed last year's record-breaking Carlton fires, US Forest Service fire spokesman Mike Ferris told AFP yesterday.
The Okanogan fire had grown to more than 250,000 acres (104,000 hectares) yesterday, according to the National Interagency Fire Center (NIFC), which said the blaze was only 10 percent contained.
Three firefighters were killed battling a portion of the Okanogan fire last week and 1,250 people are currently helping quell the blaze.
That combined damage makes the current fires "certainly the most severe in terms of timing of multiple large fires simultaneously," Jaime Smith, the governor's spokeswoman, told AFP yesterday.

President Barack Obama has approved Inslee's request for a federal declaration of emergency, which releases federal funds to help the state pay for the cost of fighting the blazes.
The Okanogan fire alone has already cost USD 8.5 million to date, the NIFC said yesterday.
Seven hundred members of the Washington National Guard were added to the state-wide firefighting effort Sunday and helicopters from surrounding states were brought in to help.
