Wet weather is forecasted to return to Napa by Friday in time for another rainy weekend, according to the National Weather Service forecast.
Showers were expected to interrupt a dry Wednesday by Wednesday evening, but taper off by Thursday morning, according to the National Weather Service. The Weather Service forecasted showers would return Friday and continue through Saturday.
“There’s a conveyor belt of moisture coming in from the Pacific,” said Judy Fossum, a broadcast meteorologist with DayWeather.
Fossum said the breaks in storms should allow the ground to dry out a bit.
In between the rain, Fossum said there could be fog and even frost overnight and into the mornings. Temperatures were forecast to drop into the 30s Wednesday night, but bump back up to the 50s during the day Thursday, she said.
“They’re fairly cool systems,” she said. She did not expect snow to come to Napa, saying the freezing temperatures should last only a brief periods.
Rick Thomasser, operations manager for the Napa County Flood Control District, said he does not expect waterways to flood with the upcoming stream of storms.
“So far, so good,” he said. “That may change as the week goes on. As long as we have some breaks in between we should be good.”
Thomasser said the worst rain should be Friday night and should be less than what Napa experienced on Christmas. He said he did not see any flood warnings through the end of the year.
On Sunday afternoon, the Napa Creek reached a height of 11.69 feet, which would have caused a flood if not for the recent flood improvements on the creek, Thomasser said.
“(10.5 feet) was what we originally called flood stage before the flood project,” Thomasser said. “We didn’t have any flooding on the creek. The flood improvements are working.”
Over the weekend, the Napa River at Oak Knoll Avenue, about five miles north of the city, was forecast to flood surrounding vineyards, but it ultimately crested about 1.5 feet below flood stage early Monday morning, Thomasser said.
Thomasser said the water levels were higher last weekend than they were the first weekend of December, though the earlier storms brought more rain. Thomasser said the ground is so saturated now that more water made its way into the Napa River and Creek. Water is expected to stay within its banks during this most recent storm.
By 12:33 a.m. Wednesday, a rain gauge at the Napa County Airport recorded 21.55 inches of rain since January, 7.78 of which fell since July 1, Fossum said.
City of Napa offices are closed through Jan. 2, but staff were put on alert before heading home so they could be called in if some kind of emergency, including a flood, were to happen, spokesman Barry Martin said prior to the closure.
