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

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.

The rainfall was so intense that in one dramatic example, a mudslide caused an entire house to slip down a bank into the Russian River on Tuesday.
