Cal Fire officials said Saturday the Border 2 fire in the Otay wilderness had burned 6,500 acres. From Los Angeles to the border, fire officials remain hopeful a Pacific storm late Saturday could bring enough rain and snow to slow wildfires.

Rain was falling across Southern California on Sunday, bringing some relief to thousands of firefighters battling multiple major blazes for nearly a month in the Los Angeles area, but also prompting new threats of floods and mudslides across burn-scarred lands.
