SAN DIEGO — Officials have closed Otay Mesa Road because of a grass fire, the California Highway Patrol.
The wind-driven wildfire of blackened swaths of open grassland south of Donovan State Prison. The fast-moving flames began spreading shortly after 2 p.m. near Alta and Otay Mesa roads, east of Brown Field airport and about a mile north of the U.S.-Mexico border, according to Cal Fire.
Within a half-hour, the blaze had grown to about 20 acres, said Ray Chaney, a battalion chief with the state agency. Ground crews and firefighting aircraft were dispatched to the area.
A salvage yard was potentially in the path of the fire, according to Chaney. There were no other known threats to real estate.
At about the time when the blaze broke out, another one was reported off State Route 78, east of Ramona. Personnel aboard an air tanker were able to quickly extinguish the small inland “spot fire,” the chief said.
