Thousands of firefighters working through the night took advantage of cool, moist air as they built containment lines around a massive wildfire that destroyed six houses north of Los Angeles.
U.S. Forest Service spokesman Ed Gillilland says humidity levels in the 30-percent range are expected Tuesday, though crews still had to watch out for wind gusts that could carry embers.
The fire that consumed 50 square miles is 60 percent contained.
Over the weekend the blaze spread rapidly through old, dry brush with help from gusty winds and soaring temperatures.
Six houses burned to the ground and nine more were damaged.
Some 3,000 residents in the rural communities of Lake Hughes and Lake Elizabeth were allowed to return home Monday.
The cause of the fire was under investigation.
