The first storm from the tail end of an atmospheric river brought light to moderate rain throughout the Los Angeles area. A second storm is already making its way toward the region. The National Weather Service said the first storm system underperformed across most of the area.

The incoming rain has sparked concerns about toxic debris in the burn scar areas. Tom Wait and Nicole Comstock report.

After the region was devastated by three massive wildfires last month – the Palisades, Hughes and Eaton fires – crews prepared for potential debris flow in burn scar areas.
