MIDDLETOWN, Calif. – The latest on wildfires raging in drought-stricken California (all times local):

9:10 a.m.

A fire in the Gold Rush country of the Sierra Nevada foothills that has now charred nearly 112 miles was more than one-third contained Tuesday.

Still, 6,400 structures remained threatened with evacuations in Amador and Calaveras counties. The fire has destroyed nearly 200 homes and outbuildings and damaged a dozen more.

East of Fresno, California's largest active wildfire has moved away from the Sierra Nevada's Giant Sequoia trees, some of which are 3,000 years old. The fire, sparked by lightning July 31, had charred 217 square miles and was 40 percent contained Tuesday.

8 a.m.

The deadly and destructive wildfire that sped through three Northern California counties has grown to 104 square miles Tuesday. It is now 15 percent contained.

For a third morning, people are waking up at evacuation centers, some still wondering if their homes are standing or leveled by the massive fire burning in parts of rural Lake, Napa and Sonoma counties, about 100 miles north of San Francisco.

At least four firefighters have been injured. One woman died in her home.

Authorities say 585 homes are known to be destroyed. More homes and structures are also known to be razed, but the exact number remained unclear Tuesday. Nine thousand homes remain threatened.

Authorities say some people also still remain unaccounted for Tuesday. But they could be staying with relatives, on vacation or elsewhere and not impacted by the fire.
