The NWS says excessive rainfall is expected to cause flooding along the Russian River, affecting roadways and agricultural land.

Sonoma County drenched by deluge that reached a peak Tuesday, raising the Russian River toward flood stage, closing dozens of roads, including HIghway 101 in Windsor, and causing mudslides, one of which sent a Forestville vacation home into the Russian River.

An atmospheric river brought additional rain, strong winds, and flooding to the Bay Area Tuesday, and thunderstorms were threatening to add to the storm's impacts.
