DRYDEN, Wash. (AP) -- Firefighters across central Washington worked to gain the upper hand on several wildfires as forecasters predicted possible new lightning strikes this weekend.
About 30 homes remained evacuated, with residents of another 40-50 homes put on notice they might have to leave because of the Fischer fire near here, about 20 miles northwest of Wenatchee. The fire was estimated at 2,100 acres Friday night, fire information officer Stefani O'Connor said.
The fire breached a bulldozer line on the north side Friday and its active burning sent up a smoke plume visible in East Wenatchee, O'Connor said.
Bulldozer crews and firefighters on foot were scheduled to work through the night, building fire line, she said.
Near Naches, northwest of Yakima, residents of seven homes that had been evacuated along a mountain road were allowed to return Friday night. The nearby Mud Lake fire was estimated at about 4,200 acres, said Dale Warriner, fire information officer.
Residents of another 45 homes along the Naches River were on notice they might have to flee if the fire grew. The fire was burning in grass, sagebrush and timber. It was 75 percent contained Friday night.
About 575 firefighters were assigned to the Mud Lake fire.
``The fire hasn't grown in the last 36 hours,'' Warriner said, but added fire crews remained alert for possible thunderstorms.
Weather predictions for the weekend included continued high temperatures and low humidity, with the possible addition of dry thunderstorms and lightning.
``It all adds up to high potential for new starts from the lightning and erratic fire behavior from existing fires,'' said Carol Tocco, spokeswoman for the Northwest Interagency Fire Center in Portland, Ore.
More than 850 firefighters were assigned to the Fischer fire, which was burning on private, state and national forest land. It was 30 percent contained and was believed to be human-caused.
About 550 firefighters continued to monitor a complex of three fires burning near Lake Chelan in north-central Washington. The Pot Peak-Sisi Ridge complex remained at 46,970 acres and was 85 percent contained.
Lightning caused all three fires in the complex _ the Pot Peak fire on June 26 and the Deep Harbor and Sisi Ridge fires on July 19. The Deep Harbor fire burned a dock and picnic shelter at a campground.
The cost of fighting the three fires stands at more than $20 million.
In far north-central Washington, about 140 firefighters were fighting the lightning-cased Mebee fire about a half-mile north of the North Cascades Highway. The fire was estimated at 234 acres. The highway remained open.
About 70 firefighters were assigned to the Rattlesnake Peak fire about 40 miles west of Yakima. The lightning-caused fire has burned about 590 acres in an area that had not burned for 60 years.
