State Department of Natural Resources officials are closing down volunteer-intake centers and saying they have all the help they need to fight Washington's largest fire ever -- the Okanogan Complex.

Thousands of volunteers have gone through crash-course fire training, helped operate heavy equipment and directed other other volunteers to community service opportunities since the call for help went out last week, but for the moment the needs are being met DNR announced in a Thursday morning tweet.

“The outpouring of support has been incredibly heartwarming and humbling,” said Mary Verner, deputy for DNR’s statewide wildfire program.

More than 3,000 people offered to help at volunteer sign-up centers in Omak and Colville in the past week.

The fire has burned more than 400 square miles and destroyed numerous homes and buildings.

Three firefighters have died battling the catastrophic fire.
