Toppled trees and road closures as Sonoma County weathers latest winter storm
It wasn’t an atmospheric river and it didn’t come down like recent deluges, but the latest storm to hit Sonoma County put the region closer to some of its wettest rain years by the end of Tuesday.
It also caused a fair share of havoc, with saturated ground and gusty winds contributing to downed trees and rock slides across the region.

Helena Zappelli had what may have been the closest call.
A large cypress toppled 10 feet from her Humboldt Street home in Santa Rosa’s Junior College neighborhood and crushed her Kia Soul.
“I feel damn lucky because it was raining and I go smoke in my car, and I was just about to do that,” she said.
On Monte Verde Drive in east Santa Rosa, several large branches fell from what appeared to be a large oak and crushed a Ford Edge SUV.
“One of my employees was taking out the recycling and it fell and scared the mess out of her,” said Andrea Quintana, administrator of a nearby long term care facility.
The branches, which crushed the car of another employee of the facility, were still blocking the road at 4:30 p.m., three hours after it had came down.
Elsewhere, a tree and power lines fell and “completely blocked St. Helena Road,” said Santa Rosa Fire Marshall, Paul Lowenthal. The road remained blocked in the late afternoon.
A rock slide also partially blocked Calistoga Road just east of St Helena Road, Lowenthal said.
Around noon Tuesday, a rock slide occurred on Moscow Road, Monte Rio Fire Chief Steve Baxman said. It covered about 20 to 30 yards of road but was quickly cleaned up, he said.
There were no reports of injuries throughout the day.
The Russian River was expected to rise by more than four feet and crest at 18.6 feet by midafternoon Wednesday in Guerneville. That would still be 10 feet below monitor level, according to California-Nevada River Center forecasts.
By 4:30 p.m. Tuesday, 0.7 inches of rain had fallen on Santa Rosa over the past 24 hours, and the same at Petaluma Municipal Airport, according to the National Weather Service.
By contrast, in the same 24-hour period, 1.23 inches fell on Venado, a remote community west of Healdsburg and typically one of the rainiest places in the North Bay.
So far this rain season, since Oct. 1, a whopping 73.64 inches have fallen on Venado, half of it in the giant series of atmospheric river storms between Dec. 26 to Jan. 17.
In Santa Rosa, the total over the same period was 39.90 inches by late Tuesday, already 10 inches over the historical average over records stretching back to 1902, according to the weather service.
Looking forward, “The forecast has remained pretty stable,” said Miles Bliss, a weather service meteorologist. “The low pressure (storm) is just going to park itself over the Bay Area, with rain remaining throughout the evening and overnight. We won’t really see it let up until Wednesday morning.”
Sonoma County is now in striking distance of some of its wettest rain years.
The top mark, 55.68 inches in Santa Rosa, came in the destructive winter of 1982-83, followed by 1940-1941, at 51.78 inches, according to the weather service.
The marks for more recent wet winters are in closer proximity: 46.54 inches in Santa Rosa in 2018-19, and 47.29 inches in 1994-95.
Since Jan. 1, the National Weather Service recorded 26.87 inches of precipitation at its official rain gauge at Charles M. Schulz—Sonoma County Airport.
The calendar-year record for Santa Rosa is 52.66 inches in 1940.
Although another storm is on the way next week, extended dry periods generally begin in April.
“I’m not familiar with any records that could be broken as far as water amounts go,” Bliss said. “It’s been a good water year so far, but not record (setting).”
Nor is it the wettest annual first quarter of the past five years, according to National Weather Service data.
Harder hit was 2019 when 32.79 inches of rain was recorded at the airport during the first three months of that year. Just two years earlier, in 2017, 37 inches of rain was recorded from January through March.
