The latest on wildfires in Washington state, including those that killed three firefighters (all times local):

7:50 a.m.

A multitude of large wildfires burning across arid Washington state have so overtaxed firefighters that officials took the unprecedented step of calling for volunteers to help fight the flames.

The state Department of Natural Resources said late Thursday that it would review civilians' offers to help and send them where they would be most useful. Volunteers could start applying Friday at centers in the communities of Omak and Colville.

It is the first time the state has asked for volunteers as an explosive fire season has led to the deaths of three firefighters and the evacuation of entire towns.

It comes even after fire managers from Australia and New Zealand were recruited to help combat blazes in the West.
