The evacuation area for the Border 2 fire stretches east to state Route 94 and west to Lower Otay Lake, warnings issued for southwest side of lake.

The fire that broke out near the U.S.-Mexico border was 10% contained as of Friday morning. It was one of several wildfires that started Thursday.

A fast-moving wildfire erupted several miles north of the U.S.-Mexico border in the San Diego area, blackening thousands of open acres as ground and airborne crews worked Friday to quell the flames amid arid and blustery Santa Ana conditions.

Firefighters have slowed the spread of a huge wildfire churning through rugged mountains north of Los Angeles where dangerous winds gained strength again.

The fire threat remains critical in Southern California, where thousands of residents were under evacuation orders Wednesday as fire crews battled the out-of-control Hughes Fire near Castaic, a suburb in the foothills and mountains of northern Los Angeles County.
