POLLOCK PINES, Calif. (KGO) -- The Caldor Wildfire is burning out of control in El Dorado County, prompting new evacuation orders along Highway 50.
Right now, the fire is nearly 54,000 acres, about twice the size of San Francisco, and zero percent contained. On Tuesday, the blaze was 6,500 acres but exploded in size as high temperatures, low humidity and gusts drove the flames.
The fire has already devastated the town of Grizzly Flats, a forest community of about 1,200 people. Few homes were left standing in Grizzly Flats, where streets were littered with downed power lines and poles. Houses were reduced to smoldering ash and twisted metal with only chimneys rising above the ruins. A post office and elementary school were also destroyed.
CAL FIRE issued new evacuation orders Tuesday night for the south side of Highway 50 north of Sly Park and extends west to Snows Rd. Those orders also include the north side of Highway 50 from Larsen Dr. to the west and Ice House to the east.

Gov. Gavin Newsom proclaimed a state of emergency in El Dorado County, where authorities were considering closing the entire El Dorado National Forest.
"We know this fire has done things that nobody could have predicted, but that's how firefighting has been in the state this year," El Dorado National Forest Supervisor Chief Jeff Marsolais said at a briefing.
The cause of the fire is under investigation.
