NAPA COUNTY --
Cal Fire crews are battling a fast-spreading fire burning near Lake Berryessa.
The fire reportedly started with a vehicle and grew into a vegetation fire, but investigators say the cause is still under investigation. According to Cal Fire, it had burned about 4,000 acres as of 8:30 p.m. It is 5 percent contained.
The fire started about 2:30 p.m. near Highway 128 and Greaves Road near Lake Berryessa and is affecting the Canyon Creek Resort area. It is being called the Wragg Fire.
The fire is traveling at a rapid rate. The terrain in the area is brush covered, rugged and steep, with difficult access for firefighters. Strong winds also caused the fire to spread quickly.
"The winds were predominately eastward, swirling, gusting, changing direction ... so it moved the fire in a bunch of different directions ... mostly moving eastward from where it started," Cal Fire Captain Joe Fletcher said.
Ground crews and air resources are working on perimeter control and containment. Nearly 400 firefighters are battling the blaze. Six tankers were working the blaze.
As the fire burned into the evening it jumped Putah Creek and Highway 128 at least twice, forcing closure of the road.
Evacuations have been ordered in the Cold Canyon area, including the Canyon Creek campground, according to Cal Fire. Additional evacuations are being ordered in the Mix Canyon area of Solano County.
The Lake Solano Campground and Quail Ridge area of South Lake Solano are being evacuated, as well.
About 150 structures are threatened.
"It was just a wall of flame," said evacuee Jeff Crossley as he described what he watched all afternoon.
It's what he could see from his Solano County home near Digger Pine Ridge and Pleasants Valley Road - something he hopes to never see again.
"The sheriff came by and told us we had to get out," he said.
So the Crossleys and dozens of others did just that -- packing up to push themselves away from an erratic, advancing adversary.
Humans were not the only ones forced to run.
But horses from Haraga's Emerald Hills Horse Ranch couldn't go on their own.
They needed trainers' hands and a trailer to get to safety in Davis.
Red Cross has opened an Evacuation Center at the Winters Community Center, 201 Railroad Ave.
A large animal evacuation center has been set up at 29775 County Road 31 in Winters.
Smoke from the fire can be seen across the Sacramento region.
