The mudslide was reported at approximately 12:30 p.m. at the intersection of Westside Road and Rio Vista Road in Forestville, the sheriff's office said in a Facebook post. The house, which was unoccupied, was later spotted downstream, Wood said.

A house was swept into the Russian River by a mudslide in Forestville near the Forest Hills Bridge Tuesday afternoon as an atmospheric river battered Northern California.

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