More than an inch of rain fell in many areas, loosening Los Angeles hillsides burned bare by the recent blaze near the Pacific Palisades neighborhood.

The wet weather will bring relief to Southern California after a prolonged period of dryness, but there’s concern that any bursts of heavy rainfall could cause flooding.

The return of the rain in Los Angeles has triggered Flash Flood Warnings, mudslides and debris flows in burn-scar areas, forcing officials to close roads and schools in the region.
