OTAY MESA, Calif. — Cal Fire San Diego County crews responded to a multi-acre brush fire near the Lower Otay Lake Saturday evening.

The fire broke out around 5 p.m. near Wueste Way in Otay Mesa, according to Cal Fire. By 6:45, fire crews were able to stop forward progress at about 10 acres.

The department said in a post on X that firefighters will remain on scene to mop up hot spots and strengthen control lines throughout the night.

According to Cal Fire, the fire had the potential to burn upwards of 20 acres, due in part to terrain near the site making ground resource access difficult.

There was no threat to structures with the brush fire and no evacuations were initiated for surrounding areas.
