Flash Floods Trigger Mudslides In Southern California

Nearly 40 miles of Interstate 5 in Southern California were shut down last night after flash flooding sent mud and rocks down onto the roadways. More than 100 people were stranded and some cars were trapped in up to six feet of mud.

Dr. Greg Postel of The Weather Channel tells Here & Now’s Robin Young about the weather systems that led to the flash floods and how the upcoming El Nino may affect the region this winter.
