As of 7 a.m. Wednesday, the Russian River in Guerneville had risen above 36 feet, entering the moderate flood stage, where waters typically inundate the Mirabel RV Park & Campground in Forestville. Multiple businesses and homes in low-lying areas likely experienced flooding. It’s unclear if the river has peaked in Guerneville.

The rain-swollen Russian River reached flood stage in multiple places Wednesday in the wake of an atmospheric river-fueled storm that brought a deluge of rain and lashing winds to the Bay Area. National Weather Service officials issued a flood watch Wednesday afternoon for portions of Sonoma and Marin counties as the region prepared for another round of rain on Thursday.

Flooding continues to threaten communities along the Russian River in Sonoma County, with evacuation orders still in effect. In Healdsburg, a mudslide has damaged several homes. Crews worked to clear debris late Tuesday.
