The weather is about to get much more intense in California. A massive wall of rain is heading to the northern part of the state, and communities are bracing for flash flooding and dangerous mudslides.
The storm system heading to the West Coast is so ferocious it's known as a "bomb cyclone," and it's helping to drive a river of moisture towards northern California. Massive rainfall and strong winds are on the way. In areas scorched bare by wildfires, flash flooding and mudslides could pose grave danger.
"The water flows off instead of soaking in and it can start picking up pebbles and then rocks, boulders, trees. And it can be severely damaging," Marty Ralph, an expert on weather and water extremes at the University of California in San Diego, told CBS News.
