BIG SUR, Calif. — Firefighters pushed back a blaze threatening this small coastal community just enough to allow hundreds of people to check on their homes Tuesday as a separate fire 300 miles north forced residents of other towns to evacuate.

Fire crews have been straining to cover 330 active California wildfires, many of which were ignited by a lightning storm more than two weeks ago. A heat wave forecast to linger in much of the state until the weekend was making the job all the more difficult.

Winds as high as 30 mph fanned a blaze northeast of Sacramento in Butte County, where firefighters went door to door overnight to evacuate 800 to 1,000 residents from the towns of Concow and Yankee Hill. Nearby Paradise, where a fire destroyed 74 homes last month, was also ordered evacuated, along with Ono, a rural town about 170 miles north of Sacramento.

"Now you're in a hell of a fire fight," said Todd Simmons, a spokesman for the California Department of Forestry and Fire Protection.

Five structures have been destroyed, and the complex of fires in Butte County was about 55 percent contained.

At least 23 homes and 25 other structures have been destroyed to the south in the Big Sur area, where flames have marched over more than 125 square miles of forest land since June 21.

Although that fire is far from controlled — the rugged terrain has kept containment at 18 percent into the fire's third week — authorities lifted the mandatory evacuation order issued for 25 miles of the 31-mile stretch along the Pacific Coast Highway that had been closed.

Many of the 1,500 evacuated residents of Big Sur headed home Tuesday morning through smoke and ash, anxious to gauge the damage.

Dena Angelique, 34, unloaded hastily packed bags of books, photos, art supplies and clothes from the back of her dusty Toyota 4Runner after a week away from her home.

She was relieved to find the fire had stopped within 100 yards of the wood-frame house, though it had charred the nearby mountainside. She wasn't sure how long she would stay; smoke and ashes still floated among the blackened remains of oak and pine, burning her throat.

"It was so insane watching the whole hillside burning," she said. "It's so nice to come back and know that we're safer here now."

Officials, however, cautioned that the lifted evacuation orders did not mean conditions had drastically improved.

"They still have an awful lot of active fire there. ... There were 2,500 residences still threatened," said U.S. Forest Service spokeswoman Juanita Freel. She said officials were trying to be sensitive to residents' needs to check on their properties.

Some homes in southern Santa Barbara County also were still threatened by another fire in the Los Padres National Forest above the city of Goleta.

Mandatory evacuation orders were lifted for many of the 275 threatened homes, but 3,200 other homes were in areas where residents had been warned to be ready to leave. That fire is about 50 percent contained.
