OLYMPIA, Wash. -

 A shift in winds Monday is helping firefighters at a couple of wildfires in southwest Washington.

Department of Natural Resources spokeswoman Karen Ripley says they grew Sunday under dry easterly winds. But winds have shifted to an onshore flow, bringing cooler, more-humid air.

About 100 firefighters with helicopters are trying to control a fire that has burned about 100 acres near the eastern end of Riffe Lake in Lewis County. It's burning debris in a recently logged area.

Another fire has burned about 60 acres of logging debris in the Capitol Forest near Littlerock in Thurston County. Ripley says about 100 firefighters are trying to contain the fire on steep terrain with help from helicopters.

She also says firefighters are mopping up smaller fires near Tenino and La Center.
