PLYMOUTH, Calif. (AP) -- Fire officials say the Sand Fire has burned about 3,800 acres in Amador and El Dorado counties since Friday.
CalFire spokesman Lynne Tolmachoff says 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.
Tolmachoff says the fire could grow again Sunday as firefighters brace for high wind and triple-digit heat.
Meanwhile, a wildfire that began 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.
