MENDOCINO Co., 1/29/24 – After receiving a taste of springlike weather, Mendocino County is preparing for yet another winter storm; this one is expected to bring high winds, flooding and possible landslides to the region this week. While rain will start countywide on the evening of Tuesday, Jan. 30, the bulk of the precipitation will be on Wednesday, Jan. 31, with rain continuing on Thursday, Feb 1.
As a result of the impending storm, National Weather Service Eureka (NWS Eureka) has issued a flood watch for the entire county, as well as either a wind advisory or high wind watch for the county depending on the location.
Below you can find the forecast, current as of 3:30 p.m. Monday, Jan. 29. We have also included some additional resources at the end of the article. Be sure to bookmark our winter weather info guide — you can also find more information about FEMA assistance, CalFresh replacements, and other storm aid on our website.
Rain will bring up to 6.5 inches of rain to the county Tuesday through Thursday increasing likelihood of river and roadway flooding
According to NWS Eureka, coastal areas can expect between 3.7 and 5.75 inches of rain and inland areas between 2.6 and 6.5 inches of rain starting the evening of Tuesday, Jan. 30 through the evening of Thursday, Feb. 1. The highest impact will be on Wednesday, Jan. 31, which will offer the heaviest rain.
The highest elevations will see the heaviest rain and highest precipitation amounts. Some areas, particularly the coast and Anderson Valley, may experience thunderstorms Wednesday evening. No snow is forecasted with this specific system, even though the chance of snow is in the forecast for Leggett, Round Valley and Laytonville on Friday, Feb. 2.
As a result, NWS Eureka has issued a series of flood watches for the entire county, which start and stop at various times depending on the flood threat in each microclimate. Specific details are listed below in the more detailed forecast. According to NWS Eureka “flooding caused by excessive rainfall is possible” and “You should monitor later forecasts and be alert for possible flood warnings. Those living in areas prone to flooding should be prepared to take action should flooding develop.”
The Navarro River may flood in low lying areas, which may result in the closure of CA-128 from CA-1 to Masonite Rd. The Russian River in Hopland is also expected to reach flood stage on Saturday and again on Monday per NWS Eureka’s forecast. The Garcia River may also flood along CA-1. NWS Eureka forecasts flooding taking place between the evening on Wednesday and early morning on Thursday.
NWS Eureka advises that drivers do not try to drive through floodwaters. All it takes is one foot of water to push a car off the road. Turn around, don’t drown.
