The Associated Press reports:
Two California communities north of San Francisco were accessible only by boat Wednesday after a rain-swollen river overflowed its banks and inundated low-lying areas around them overnight, authorities said.
One of them, the small city of Guerneville, “is officially an island,” the Sonoma County Sheriff’s Office said in a statement. A short time later, an official said the nearby town of Monte Rio was also isolated by floodwaters with all roads leading to it swamped.
The swollen Russian River was forecast to rise more throughout the day, engorged by days of rain from western U.S. storms that has also dumped heavy snow in the Sierra Nevada, throughout the Pacific Northwest and into Montana.
The San Francisco Chronicle reports:
The rains may have subsided but the Russian River near Guerneville in Sonoma County continues to swell over its banks and was at 42.5 feet at 9 a.m. Wednesday, 10.4 feet above flood stage. The waterway is forecast to crest at 46 feet around 9 p.m. Wednesday, and the Sonoma County Sheriff’s Office said the town of Guerneville is landlocked.
Last week, before the storm, the river was at about 13 feet. The sheriff’s office issued mandatory evacuations for 24 towns and neighborhoods along the river on Tuesday, and those who haven’t left the area will be trapped as all roads in and out are flooded.
If the river rises to 46 feet, the area will see the worst flooding it has experienced in 24 years. Large swaths of the small town of Guerneville and the neighboring communities of Rio Nido and Monte Rio will be underwater.

Floodwaters have overwhelmed parts of the North Bay, including this area in Forestville.
Good news? The heaviest rain is gone. Bad news? The Russian River at Guerneville isn’t expected to crest until tonight. https://t.co/PGZm1Rmc8R pic.twitter.com/jXVRfseHHQ
