A wildfire in grass and vineyard outside Hopland in Mendocino County grew to 142 acres overnight, after breaking out Tuesday afternoon along the western edge of Highway 101.
The blaze, estimated at 80 percent containment Wednesday, started about 12:40 p.m. Tuesday near Crawford Ranch Road around the same time a grape truck with a smoking engine was seen in the area, Cal Fire said. On Wednesday, it was still unclear if there was any connection, said Cal Fire Spokeswoman Tricia Austin.
Three firefighters have suffered minor injuries.
