The so-called Gate Fire, which forced hundreds of people to evacuate a popular campground and small community southeast of San Diego, remained at 2,056 acres and was 95 percent surrounded as of 6 p.m. Monday, confirmed Cal Fire.
Early morning fog and cooler temperatures helped firefighters overnight as they faught the wildfire.
"The overnight temps and humidity levels allowed firefighters to make progress overnight although we are expecting another warm and dry day in the fire area," said CAL FIRE Fire Captain/Information Officer Issac Sanchez.
On Sunday, Cal Fire confirmed that the Gate Fire was under a criminal investigation.
Investigators spoke to a witness who posted an Instagram video that appears to show people starting the fire. The witness cooperated with officials and is not under investigation, Cal Fire said.
As of 6 a.m. Monday, the Gate Fire had burned 2,056 acres in the remote area near Pio Pico RV Resort and Campground in San Diego's East County. At the time, Sanchez said the fire was 75 percent contained.
All evacuation orders and warnings have been lifted.
As of 10:33 a.m., the Pio Pico campground was reopened, according to a campground representative. Anyone who paid for two nights at the campground will be reimbursed for the days they were forced to relocate.
The blaze broke out Saturday south of Jamul and spread rapidly through grass and brush.
Campers and residents of nearby Dulzura were evacuated. An evacuation warning remained in effect for that community, but residents were allowed to return.
At least two dozen RVs were parked in the Wal-Mart parking lot in Eastlake because of the evacuation warning issued over the weekend.
Authorities initially kept the campgrounds under evacuation because of infrastructure damage. They did not reveal the extent of the damage.
Officials would not confirm if they had any suspects or any other details of the investigation.
