Back home out west to mandatory evacuations triggered by a massive mudslide along the Russian river in sonoma county, California. Matt Gutman has the latest. Reporter: That flooding triggering widespread rescues in northern California as record rain fell across the region. The vehicle in the water out there is started in the middle of the road and as you can see out there it’s moved off to the side.
