Residents living along the Russian River from Healdsburg to Jenner are under an evacuation warning following Wednesday's storm, the Sonoma County Sheriff's Office said.
It's expected that the river will crest at 33 feet by Thursday night and into the early hours on Friday.
The river is expected to recede below flood stage by Friday afternoon, but forecasted to flood again at 40 feet on Sunday night and into Monday.
"For your safety, prepare to leave the areas below the 40-foot flood level along the Russian River," the sheriff's office said in an advisory. "Be sure to take essential items, such as medicines with you. If you live above the 40-foot level, your access may be reduced or eliminated due to flood waters.
