PLACERVILLE, Calif. (AP) — Helpful rains and more than 8,000 firefighters brought solid advances against a huge wildfire in Northern California, leading evacuations to dwindle and the number of threatened homes to fall from thousands to just a few hundred.

Calls for evacuations in two communities were reduced from mandatory to voluntary, leaving just one neighborhood under strict orders to stay away from their homes, the El Dorado County Sheriff's Department said in a statement. It wasn't immediately clear how many people remained evacuated.

The rains had brought fears of flooding and dangerous conditions in the King Fire's huge burn area east of Sacramento, but they remained light and helpful to the firefight. A flash flood warning in effect for several hours was called off early Thursday evening.

By evening, state fire officials said fewer than 300 structures were still threatened after putting the figure at 12,000 when the day started.

The blaze was 55 percent contained — up from 43 percent at the beginning of the day — and showed no growth after burning almost 150 square miles and destroying a dozen homes near the town of Pollock Pines.

"The rain is definitely allowing the firefighters to make progress on containment," said Dana Welsh, a spokeswoman for the U.S. Forest Service.

Large areas of the fire remain uncontained, so the blaze could still spread when the rain stops, Welsh added.

Forecasters say more rain could come during the weekend, stirring fears of possible mudslides and slippery roads that would make firefighting more dangerous, Welsh said.

Wayne Allen Huntsman, 37, has been charged with starting the fire. He has pleaded not guilty to arson and remains in jail on $10 million bail.

The fire has become the second priciest blaze in California this year, costing more than $50 million to fight since it began nearly two weeks ago. The state spent more than $85 million fighting a fire in Klamath National Forest along the California-Oregon border.

The King Fire is one of nearly 5,000 wildfires in California this year, a big increase compared with an average year of about 3,900.
