Updated at 7:07 p.m. Aug. 13

Cal Fire crews battled a 350-acre brush fire southeast of Julian Monday as more lightning-sparked brush fires lit up, blackening hundreds of open acres east of Julian as well as near the U.S.-Mexico border.

The so-called Vallecito Fire erupted about 8 p.m. Sunday in the vicinity of the Mason Valley Truck Trail, according to the state firefighting agency.

There were no immediately threats to structures, said Cal Fire Battalion Chief Nick Schuler, and no roads are closed.

More than 600 lightning strikes were reported in San Diego County on Monday, Schuler said. Electrical-storm activity sparked two other fires near Scissors Crossing, north of the initial burn area. One, designated as the Wilson Fire, had grown to roughly 600 acres by shortly after 5 p.m., by which time the other one, the Stewart Fire, was about 50 acres in size.

Schuler told Patch that aircraft was helping battle the flames.

The Vallecito Fire remains zero percent contained.
