PLYMOUTH, California: Firefighters in Northern California on Sunday battled a wildfire that has destroyed 10 homes and forced hundreds of evacuations in the Sierra Nevada foothills, while a fire near Yosemite National Park destroyed one home and grew significantly overnight.

East of Sacramento, the Sand Fire has burned about 3,800 acres, roughly 6 square miles of steep, rugged terrain near wine-growing regions in Amador and El Dorado counties since Friday, according to the California Department of Forestry and Fire Protection.

The fire, which has also destroyed seven outbuildings, was 35 percent contained Sunday morning, but threatens hundreds of homes, CalFire spokeswoman Lynne Tolmachoff said. It could grow again Sunday as firefighters brace for high winds and temperatures above 100 degrees Fahrenheit in the drought-stricken region.

“All of the vegetation in the area is struggling. It’s burning very easily,” Tolmachoff said. “It causes the fire to be a lot hotter and to spread more easily.”

West of Yosemite National Park, a wildfire that began Saturday afternoon quadrupled in size overnight to 2,100 acres, or more than 3 square miles, and was burning out of control Sunday. It destroyed one home in the small community of Foresta, Ranger Scott Gediman said. The park itself remained open.

The Sand Fire in the Sierra foothills has prompted authorities to evacuate about 500 homes and close several roads near the town of Plymouth.
