Firefighters in northern California are battling a wildfire that has destroyed 10 homes and forced hundreds of evacuations in the Sierra Nevada foothills, while a fire near Yosemite grew significantly overnight.
Fire officials said the Sand Fire has burned about 3,800 acres in Amador and El Dorado counties since Friday.
Lynne Tolmachoff, spokeswoman the California Department of Forestry and Fire Protection (Cal Fire), said the fire continues to threaten hundreds of homes east of Sacramento.
Authorities have evacuated about 500 homes and closed roads near Plymouth in Amador County's wine-growing region.
Ms Tolmachoff says the fire could grow again on Sunday as firefighters brace for high wind and triple-digit heat.
Meanwhile, a wildfire that began on Saturday has reached 2,100 acres, destroying one home in a small community outside Yosemite National Park.
Park Ranger Scott Gediman says no others are immediately threatened.
