More than a dozen wildfires raged across Northern California on Tuesday morning, with the biggest ones scorching the state's famous wine country, killing at least 11 people and burning more than 1,500 homes and businesses, authorities said.

The fires were burning in California's wine country destinations -- Napa, Sonoma and Mendocino counties -- as well as Yuba County, north of Sacramento, with flames ripping through the lush, picturesque landscape.
