Flood Watch National Weather Service Eureka CA 1002 PM PST Tue Dec 23 2025 Coastal Del Norte-Del Norte Interior-Northern Humboldt Coast- Southwestern Humboldt-Northern Humboldt Interior-Southern Humboldt Interior-Northern Trinity-Southern Trinity-Mendocino Coast-Northwestern Mendocino Interior-Northeastern Mendocino Interior-Southwestern Mendocino Interior-Southeastern Mendocino Interior-Northern Lake-Southern Lake- 1002 PM PST Tue Dec 23 2025 ...FLOOD WATCH REMAINS IN EFFECT THROUGH FRIDAY EVENING... * WHAT...Flooding caused by excessive rainfall continues to be possible. * WHERE...Del Norte County, Humboldt County, Trinity County, Mendocino County, and Lake County. * WHEN...Through Friday evening. * IMPACTS...Excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations. Creeks and streams may rise out of their banks. Flooding may occur in poor drainage and urban areas. Area creeks and streams are running high and could flood with more heavy rain. * ADDITIONAL DETAILS... - Additional rounds of heavy rain expected through Friday night. An additional 3-6, locally up to 9 inches of total rain is possible through Friday. There will be breaks in the heavy precipitation, but heavy rain falling on already saturated ground will promote flooding impacts. - http://www.weather.gov/safety/flood PRECAUTIONARY/PREPAREDNESS ACTIONS... 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. &&

There is a Marginal Severe Storm Risk for your location. Continue reading for today's outlook from the National Weather Service's Storm Prediction Center. -------------------- National Severe Storm Outlook THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS MUCH OF COASTAL CALIFORNIA AND PORTIONS OF THE CENTRAL VALLEY SUMMARY An isolated risk for severe gusts/localized wind damage and perhaps a brief tornado will be possible today into this evening along much of the California Coast and portions of the Central Valley. California Recent satellite imagery shows a mid/upper-level low over the eastern Pacific and a negative-tilt shortwave trough moving northward along the northern CA and OR Coast. An upstream mid-level jet and associated vorticity maximum will move through the base of the eastern Pacific upper low/trough and approach the San Francisco Bay and northern CA vicinity this evening. Strong to locally severe thunderstorms capable of producing mainly isolated severe/damaging winds will remain possible with convection today into this evening. Weak instability is forecast to persist across much of coastal CA into the Central Valley, with cool surface temperatures, saturated profiles, and modest lapse rates aloft (reference the 12Z OAK sounding) limiting the development of greater MUCAPE. Still, a favorable kinematic environment with enhanced west-southwesterly mid/upper-level flow will conditionally support occasional strong to severe convection, contingent on sufficiently deep/sustained updraft development. Low-level hodographs are forecast to remain enlarged enough to yield a low risk for a brief tornado across much of the Marginal Risk area. Consensus of latest model guidance indicates low/mid-level flow will weaken somewhat this afternoon before gradually re-intensifying this evening as the next embedded shortwave trough and associated mid-level jet overspread coastal northern/central CA. A mix of linear bands and cellular convective structures may continue to pose an intermittent risk for isolated damaging gusts and perhaps a brief tornado into this evening/tonight, before the severe threat gradually diminishes towards 12Z early Friday morning.
