The two fires that make up the Mendocino Complex of Fires were extremely active Saturday, growing from 9,500 to 28,000 acres, almost tripling in size according to very conservative figures released Sunday morning by CAL FIRE.

Both fires started in Mendocino County around noon on July 27 but have burned into Lake County.

The Ranch Fire is 8 miles northwest of Ukiah, California and as of Saturday night had remained east of Highway 20. The River Fire is farther south and Saturday night spread to a point three miles west of Lakeport, a community on the west shore of Clear Lake.

A number of areas in Mendocino and Lake County are under mandatory evacuation orders.

Four homes have burned in the River Fire, but another 4,600 are threatened.
