Shallow landslides and flooding could occur this weekend as up to 8 inches of rain pour into the North Bay during what the National Weather Service is calling a “weak atmospheric river.” Two rounds of rain, from Friday to Monday, could dump about 2 to 6 inches of rain across area valleys while coastal ranges in northwest Sonoma County, like those north of Jenner, could see up to 8 inches. Chances for landslides and flooding – quickly rising creeks and streams, and standing water on roads will increase from early Sunday to Monday morning. Officials predict the Russian River will begin rising Saturday and could reach up to about 16 1/2 feet at Hopland, which is about 1 1/2 feet above flood level.
