More than 3,700 residents have returned to their Malibu homes as weather conditions improved enough to help firefighters battling a Southern California blaze. Calmer winds and rising humidity aided firefighters as they climbed through steep canyons to fight the Franklin Fire. The weather improved so much that meteorologists said all red flag warnings were discontinued. The sheriff’s department lifted some mandatory evacuation orders on Thursday, though others remain in place. The Franklin Fire was still only 30% contained at over 4,000 acres. Officials say four homes have been destroyed and at least six others have been damaged.
