A wildfire that broke out several miles southwest of a destructive fire in Northern California doubled in size overnight, charring nearly 8 square miles.

The California Department of Forestry and Fire Protection says evacuations have been ordered for the new fire that started Sunday. Containment was not in sight Monday morning.

The blaze is burning near a wildfire that has destroyed 43 homes and 53 outbuildings and chewed up 109 square miles since it started on July 29. It is now 85 percent contained.

The new fire in dense brush and steep terrain exploded quickly Sunday afternoon, charring about 4 square miles. Firefighters and air tankers battling the original fire were reassigned to attack the new blaze. Fire officials are investigating the causes of both fires.
