Map updated Tuesday morning. Fire perimeter outlined in yellow, evacuation zones shown in red.

A 30-mile swath of Mendocino and Lake counties is under mandatory evacuation order because of two fires that started within an hour of each other Friday.

The Ranch Fire is burning northwest of the town of Upper Lake; the River Fire is 10 miles to the south, between Hopland and Lakeport.

CalFire’s Tuesday morning report said the Ranch Fire is at 47,339 acres (74 square miles) and 8 percent contained. The River Fire is at 27,069 acres (42 square miles) and 10 percent contained.

The latest perimeter map shows the River Fire burning to within a mile of Clear Lake’s west shore and also crossing Highway 175 on a stretch that has been closed to traffic.

The Ranch Fire crossed Highway 20 at one point a few miles west of Upper Lake.

As both fires moved to the north and east, much of western Lake County came under evacuation orders or advisory on Monday afternoon.

Mendocino County, to the west, lifted the evacuation orders for Hopland and Hopland Rancheria, and the first five miles of Highway 175 east of U.S. Highway 101 was reopened.
