Flames came very close to homes residents from two streets in Riverside County were advised to evacuate on Thursday night at the peak of a ferocious California wildfire.

The blaze burned about 150 acres in and around Rancho Jurupa Regional Park in California.

It was not clear how many people left their homes, but no one had sought refuge at a shelter established for evacuees.

About 200 firefighters helped by helicopters took on the blaze whose bright flames and huge plumes of smoke were visible from long distances.

The fire was 20% contained around midnight, hours after it began.

The threat to homes was mostly beaten back, but firefighters were expected to work well into Friday to contain it.

There were no reports of any injuries or homes or buildings burning, but the blaze brought down power lines and left more than 1,800 customers without power.

The National Weather Service has issued an advisory for gusty offshore winds for valleys in Riverside County and elsewhere in southern California that will be in effect until Saturday afternoon.

About 200 miles north of Los Angeles in Inyo County, a wildfire that consumed more than 400 acres in the high desert Lone Pine area was fully contained after burning for four days.
