After a very dry start to winter, two distinct rainstorms are making their way to the Southern California region.

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.

The Los Angeles area is preparing for the tail end of an atmospheric river that will bring "beneficial rain," forecasters say.
