Pushed by 25 mph winds, the blaze started Friday and had raced across 300 acres by Saturday.

Kittitas County Undersheriff Clayton Myers said Saturday morning that two homes and a shop had burned.

"The fire's still rolling," he told evacuees at Thorp High School. "The wind's starting to die down. That's going to help a lot but I don't expect it to be out for some time."

The fire started near Interstate 90 between Cle Elum and Ellensburg at about noon Friday. Myers said its cause was unknown but considered suspicious, the fourth suspicious Kittitas County fire in the past week.

No injuries were reported.

Cleo Aho, 68, of Cle Elum, said firefighters came to her door and gave her five minutes to grab her cat and dog and leave her home.

"It's not long enough," she said. "Five minutes goes so fast. ... You don't think it's ever going to happen to you."

Some of the 200 residences were seasonal cabins; Myers estimated that 90 to 100 people were displaced.

Earlier Friday, authorities in northcentral Washington ordered the evacuation of 100 homes there after a wildfire near Lake Chelan grew to 9,800 acres in 24 hours.

In the Cle Elum area fire, helicopters dropped water and planes spread fire retardant around the edges of the Morrison Creek and Sunlight Waters developments. "Every fire apparatus available" was on scene to try to protect homes, Myers said.

Authorities hoped to channel the fire away from nearby timber and toward open prairie.

Washington state emergency officials ordered state fire assistance mobilized, dispatching firefighting teams from Grant, Walla Walla and Yakima counties.

More than 130 firefighters, plus 60 fire engines and water tenders, were dispatched, said Greg Pressel of the State Patrol.

Kittitas County commissioners declared a county emergency, opening the way for additional aid, Myers said.

The Deep Harbor fire near Lake Chelan did not burn any new structures Friday and no injuries were reported, said Mike Ferris, a Forest Service spokesman.

On Thursday, it destroyed a dock and picnic shelter at a campground, he said.

The Deep Harbor evacuations, many affecting vacation homes, were ordered Friday morning, and firefighters concentrated their efforts on keeping flames away from the structures. The fire was burning about 2½ miles from the nearest home.

"The fire didn't do a lot today," National Park Service fire spokeswoman Patti Wold said Friday night. Fire officials were able to revise their acreage estimate to 9,800 acres, down from the 10,000 estimated earlier.

Three fires - Pot Peak at 15,500 acres, Sisi Ridge at 345 and Deep Harbor - were being fought jointly by about 625 firefighters. None of the three blazes threatens the communities of Chelan or Stehekin.

Smoke from those fires was so bad Friday that the Chelan-Douglas Health District issued an alert warning people with respiratory and heart conditions, the elderly and children to stay inside.

Fire managers and Chelan County officials ordered the evacuation of about 100 homes in the Fields Point community, about 25 miles northwest of the town of Chelan.

The Deep Harbor fire was started by lightning July 19 and had burned only 145 acres until Thursday, when winds began to expand it.

Sisi Ridge also was started by lightning on July 19. Pot Peak was started by lightning on June 26.
