SACRAMENTO (CBS/AP) — Officials say crews have made more progress toward taming a massive wildfire in Northern California.

U.S. Forest Service spokesman Michael Williams says more rain and high humidity on Saturday aided firefighters battling the King Fire, which did not see a major spread since it began two weeks ago.

Williams said Sunday that the fire is 87 percent contained — up 3 percent from Saturday. More than 4,800 firefighters remain on the scene to strengthen containment lines as fire suppression and repair teams assess the damage.

The blaze has destroyed about a dozen homes and nearly 70 other structures near Pollock Pines in El Dorado County.

The fire has cost more than $53 million to fight.
