California ? A wind-driven wildfire scorched more than 600 acres of brush on Monday, torched an industrial yard and forced the evacuation of two schools before firefighters gained the upper hand, officials said.

The blaze 60 miles east of Los Angeles had threatened 100 homes earlier in the day, but firefighters corralled the fire enough to call off firefighting aircraft within several hours, fire officials said.

The fire was at 640 acres – about 1 square mile – and 30 percent contained, but full containment was expected by this morning, officials said. But firefighters remained on edge because the erratic wind, which was gusting to 40 mph, could bring the blaze back to life.

No injuries were reported. The cause was under investigation.

The fire began Monday morning.
