(KGTV) - Crews were able to stop the spread of a fire that erupted in a remote area of Palomar Mountain on Monday.
The so-called South Fire broke out around 3:30 p.m. near South Grade and State Park roads, according to Cal Fire officials.
U.S. Forest Service and Cal Fire firefighters on the ground and in the air fought the blaze and were able to hold it to one acre burned. Officials said the fire had the potential to burn 1,500 acres.
As of early Tuesday morning, the fire -- which may have been started by a lightning strike -- was 5 percent contained.
