Evacuations were ordered as dry, hot winds fueled a wildfire burning out of control Sunday in rural Northern California, sending a stream of smoke some 75 miles (120 kilometers) south into the San Francisco Bay Area.

The fast-moving blaze that broke out Saturday in western Yolo County charred at least 50 square miles (129 square kilometers) of dry brush and threatened more than 100 structures in ranchland northwest of Sacramento. No injuries were reported and the exact number of people evacuated was unclear. The California Department of Forestry and Fire Protection said Sunday night that there was 2 percent containment.
