NAPA VALLEY, CA—Yountville had the second-highest rainfall total from the most recent atmospheric river to hit the Bay Area, the National Weather Service reported Wednesday.
From Friday through Tuesday, the Napa Valley town received 14 inches of rain. Mount Tam, where nearly 18 inches of rain fell, had the highest rainfall total in the region, preliminary figures showed.
The rain led to flooding issues throughout the county and the North Bay. Tuesday night, the Napa River crested at 18.39 feet in St. Helena, reaching the "minor" flood stage. In Yountville, the Napa River rose to 24.27 feet — just below minor flood stage.
Due to flooding from this week's heavy rainfall, Caltrans implemented one-way traffic control on state Highway 29 in Mt. Saint Helena from Robert Louis Stevenson Park north to the Lake County line.
In Sonoma County, a mudslide caused a home to slide into the Russian River in Forestville and led to mandatory evacuation orders for residents along the river from Guerneville to Jenner.

Although Wednesday brought a slight break in the rain, a 90 percent chance of rain is forecast for Thursday in the North Bay and Napa Valley. This brings the possibility that river levels could peak higher than originally forecast, the city of Napa warned.
Moderate rainfall —mainly on Thursday —was likely to result in minor roadway ponding and slow the recession of ongoing river flooding, National Weather Service forecasters said.
The Napa County Office of Emergency Services encouraged community members to keep driving to a minimum.
"Due to the atmospheric river several county roads are currently flooded, or in danger of flooding," Napa County OES said. "Please use caution when navigating roads as not all flooded areas have yet been identified. You are encouraged to keep driving to a minimum until the rains subside. Remember turn around, don’t drown and never drive through a flooded road or area."
The city of Napa cautioned that water from the Napa River could flow over the banks in some general low-lying areas, such as:
"If you are in an area with flood potential, consider moving vehicles to higher ground," city officials said.
Personnel with the City of Napa Fire, Police, Public Works and Parks departments continue to monitor conditions and respond to any issues that occur, the city said.
The city's Corp Yard at 770 Jackson St. is stocked with sandbags for community members who need them.
