It looks like the weather won't be much help to California firefighters in the coming days.

Forecasters said a high-pressure system will keep moist marine air from coming ashore, and hot temperatures aren't helping, either.

Overnight gusts have been blowing flames across fire lines in the Sequoia National Forest. An official said the fire may have damaged a home and "some outbuildings."

North of Sacramento, hundreds of residents have been leaving the small towns of Concow and Yankee Hill after authorities issued an immediate evacuation advisory.

At least one home burned and hundreds more were threatened Tuesday by the raging fire near the Butte County communities, fire officials said Tuesday.

The wildfire, dubbed the Camp Fire, also has forced 2,000 people to evacuate, officials said.

Ash was falling in the area and the skies were clogged with smoke Tuesday. The blaze has charred about 9,600 acres and is just 5 percent contained, KCRA-TV in Sacramento reported.

Todd Simmons, a spokesman for Cal Fire, said scorching triple-digit temperatures, choking smoke and low humidity are making things tough for firefighters.

The blaze is part of a complex of fires burning over more than 45 square miles.

Meanwhile, officials said they're lifting some mandatory evacuation orders for a wildfire near Big Sur.

They said that fire is still very active, but authorities are trying to be sensitive to the residents' need to access their properties.

Fire officials had said wildfires burning near Big Sur to the north and in the Sequoia National Forest east of Bakersfield are still at least two weeks away from containment.

Fresh reinforcements from other parts of the country continue to fly into areas that need help with raging wildfires.

A wildfire near Santa Barbara was 35 percent contained Tuesday morning, and more than 2,000 residents who had to evacuate over the weekend have been allowed back home.

But the lingering fire has again knocked power out for about 36,000 customers. It's the sixth straight day that's happened in the area.
