Flooding Expected In South Central Sonoma County: NWS

SONOMA COUNTY, CA — A flood advisory for south central Sonoma County has been extended until at least 10 p.m. Friday, according to the National Weather Service San Francisco Bay Area. NWS officials say the water-level gauge at Willow Brook Creek near Penngrove reported 62 feet at 4 p.m. Friday, "meaning locations downstream of Willow Brook at Old Redwood Highway Bridge and Willow Brook at Stony Point Road will likely see flooding in two to four hours."

Some locations that will experience flooding are: Santa Rosa, Rohnert Park, Petaluma, Sebastopol, Cotati, South Santa Rosa and Graton, weather service officials said.

Rohnert Park Expressway is currently closed between Rancho Verde Mobile Home Park and Stony Point Road due to flooding.

The Petaluma Police Department issued an advisory at 4 p.m. Friday to alert residents of potential flooding at the north end of the city.

"This especially concerns the areas of Stony Point Road, Petaluma Blvd. North, Old Redwood Highway and North McDowell Blvd.," police said, noting that a weather advisory is in effect until 3:15 p.m. Saturday.

Police cautioned that at the time of their advisory, there was no flooding on the north end of town.

"It appears the tide will not influence any potential flooding during the night," police said. "The Petaluma Police and Fire Departments will continue to monitor the north end of town and issue further advisories as necessary. Everyone is asked to drive with extreme caution due to standing water and decreased visibility due to the rain. Any information or signs of flooding should be called into the Petaluma Police Department at 707-778-4326."
