Officials in central Washington are encouraging 300 families to leave their homes in the path of a fast-growing wildfire.

KING-TV reports (http://is.gd/BmdxjJ ) the Douglas County sheriff's office issued about 300 evacuation notices Sunday morning to people living in the Palisades neighborhood of Waterville.

Sheriff Harvey Gjesdal says those in the area should not wait for an evacuation notice, however, and move their family to safety if they see the fire getting closer.

Fire officials say the Douglas County complex of fires, which started Friday evening, have grown to cover about 30 square miles. No structures have been destroyed by the two fires that officials believe were started by lightning.

Fire danger in many areas of Washington state remains very high or extreme.
