Rivers across Northern California swelled from the deluge but did not flood as much as expected. Flood warnings had been issued for the Napa and Russian rivers north of San Francisco, and for the Truckee River near Lake Tahoe.
In Napa, officials had handed out more than 8,000 sandbags and about 150 tons of sand, but the city appeared to avoid any major damage.
In Nevada, rescue crews searched for a homeless man in Reno who reportedly fell into the Truckee River from a limb Sunday night.
A sudden shift in the weekend weather turned rain into snow, keeping rivers and streams largely within their banks in Reno and Sparks, Nev., and Truckee, Calif.
In southern Oregon, the Coquille and Rogue rivers were both about 2 feet above flood stage as a result of storms.
The weather service said more rivers along the coast and inland in the Willamette Valley could be flooded amid heavy rains.
A Southern Oregon man was being held on $40,000 bail after being charged with disorderly conduct and recklessly endangering rescuers after a disagreement on whether to save his three boats that went downstream, authorities said.
