Heavy rain coming to Southern California

Multiple rain storms are coming to Southern California, powered by a pineapple express. Jonathan Novack has the latest on the storm, while Laura Diaz explains how San Clemente is preparing.

Rain is once again back in Los Angeles.

It hasn't even been two weeks since Southern California last dealt with winter storms, but here we are as the region once again braces for another round of heavy rain and possible flooding.

Orange, Riverside and San Bernardino counties will be under flood watches between Thursday and Friday morning. Through Friday, up to 2.5 inches of widespread rain is expected in Southern California.

FOX 11 Meteorologist Jonathan Novack warns heavy rain and flooding will be the main concern. He adds Southern California's mountain communities may see strong winds and snow.
