MENDOCINO CO., 12/20/25 – The National Weather Service has issued a Flood Watch for the Russian River near Hopland and Talmage.
The watch is in effect from 11:15 a.m. to 6 p.m. Sunday, according to the weather service.
The Russian River is expected to approach flood stage Sunday afternoon, the weather service said. When the river reaches flood stage, state Highway 175 in Hopland often floods, which can result in road closures.
As of 8:30 a.m. Saturday, the Russian River at Hopland measured 4.8 feet. Flood stage is 15 feet.
The river-specific flood watch is in addition to a countywide flood watch in effect from Saturday afternoon through Monday morning.
“If you are in the watch area, remain alert to possible flooding,” the weather service said. “Residents and those with interests near the river should monitor rising water levels and be prepared for possible flood warnings.”
Residents in flood-prone areas are urged to monitor forecasts closely, sign up for emergency alerts at mendoready.org, know their evacuation zone, and be prepared to act should flooding occur. A list of local sandbag stations is available here.
