UPDATE, 10 p.m. Sunday:
The Russian River is no longer expected to flood in Guerneville following Sunday's heavy rains, according to revised projections from the National Weather Service.
The National Weather Service on Saturday had forecast that the river would reach flood stage in Guerneville, around 32 feet, around 2 a.m. Monday morning, and crest around noon that day at 35 feet.
However, after Sunday's storm, that projection was revised and the river is now expected to stay below flood stage, cresting at just over 27 feet around 4 a.m. Monday.
The highest recorded flood in Guerneville occurred in February 1986, when the river reached 49.5 feet, according to the National Weather Service.
Predictions of flooding on the Napa River were also downgraded Sunday, according to Napa city officials there.
The river was expected to crest in the city of Napa between 5 p.m. and 6 p.m. Sunday evening and was projected to stay within its banks, community outreach coordinator Barry Martin said.
As a precaution, Veterans Memorial Park, Oxbow Preserve Park and the Riverfront Promenade were to remain closed to the public for the remainder of Sunday.
