In Ukiah, flooding is also being reported on East Perkins Street and Vichy Spring Road in Ukiah, and crews are currently on the scene placing signage and assisting vehicles in the water, according to the CHP. Flooding is also being reported at Talmage and Babcock Lane, with at least one vehicle requiring assistance, and a road closure is going into place.

Additional road closures due to downed trees and debris have been reported, and Caltrans, CHP, and county and city crews have been hard at work responding to flooding at different locations and incidents. Please avoid the roads if at all possible, as several rivers are expected to reach flood stages and may lead to additional road closures overnight. If you approach a road that appears flooded, “turn around and don’t drown,” and avoid downed power lines.
Rain is expected to continue into Saturday, and flooding may continue into Sunday as rivers continue to rise after the storm has passed, so residents should prepare for ongoing flooding risks overnight and through the weekend.

UPDATED: 12/30/22, 12 p.m. — It has been raining across the county since last night, and the National Weather Service (NWS) is predicting that several rivers within Humboldt and Mendocino counties may reach flood stage before the rains have receded. A flood watch continues to be in effect for the majority of the North Coast, and the Russian River at Hopland, the Garcia River near Point Arena, and the Navarro River all may flood and lead to potential road closures and other impacts.
According to a recent tweet by the agency, as of 11:45 a.m. on Friday the Russian River at Hopland is currently at flood stage, which is 15 feet, and may impact traffic on State Route 175 and other roadways. The Navarro River at Navarro is approaching flood stage, which is 23 feet, at which point it could close State Route 128. The Garcia River near Point Arena is nearing 10 feet, at which point it is likely to flood State Route 1.
NWS is reporting that some areas have received up to four inches of rain since Thursday evening, and rain is currently forecast to continue until at least Saturday morning. Residents should not attempt to drive through flooded roadways but instead should turn around.
We will continue to keep you updated as the storm continues. Additional links for current information on road conditions, power outages and more are included at the bottom of this article.
MENDOCINO Co., 12/28/22 — Another round of rain is in the forecast for the North Coast, following on the heels of Monday’s atmospheric river, and the National Weather Service (NWS) in Eureka is predicting an increased possibility of flooding in the coming days.
As of the time of publication, a flood watch is in effect for the majority of Mendocino County, southern Trinity County, and northern Lake County from Thursday afternoon, December 29, until Saturday morning, December 31. Between two and four inches of rain is anticipated, with up to six inches of rain possible at higher elevations. Snow levels will be higher in elevation on Friday and Saturday across the region. From the NWS flood warning:
“Excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations. Storm drains and ditches may become clogged with debris. Rain will increase the risk of rock and mudslides. Area creeks and streams are running high and could flood with more heavy rain.”
In particular, flooding is possible at the Russian River and the Navarro River in Mendocino County, and Mad River and the Eel River at Fernbridge in Humboldt County, according to NWS. The real-time river flow data from the United States Geologic Service is available at this website.
