Floriston Warnings, Watches and Advisories

Do not drive vehicles through flooded areas. The water depth or fast flowing water/mud/debris from a flash flood will make road conditions unsafe. Do not rely soley on data presented here or other third-party websites - always check your official national and local weather service agency website, socials, radio and/or TV stations for making critical decisions related to weather events.

Please carefully read each posted Warning and Alert as it relates to the area(s) being affected.

Hydrologic Outlook issued November 17 at 5:23PM PST by NWS Eureka CA

ESFEKA * WHAT...A strong and prolonged atmospheric river will impact NW California mid to late week. Moderate to locally heavy rainfall will bring the potential for rapid rises on rivers, streams and creeks across the region. Rain will be heaviest on Wednesday with 2 to 4 inches of rain. High peaks in the King Range could see 6 to 9 inches of rain over 24 hours. Most models show more moderate but persistent rain continuing Thursday through next Saturday with most likely rainfall of 1 to 3 inches each day. Total Storm amounts could easily reach between 6 and 14 inches over 4 days, with up to 21 inches for the King Range. * WHERE...The greatest risk is for Humboldt and Del Norte Counties where soils are already near saturation. Significant rain are also expected for Mendocino and Lake Counties, though generally drier soils will reduce the flood risk. Much of the precipitation in Trinity County will likely fall as snow with snow levels in the eastern half of the county as low as 2500 feet. * WHEN...Greatest risk of heavy rain during the day on Wednesday. More moderate but prolonged rain Thursday through Saturday. The forecast is more uncertain further out. Long range models show the potential for rain to continue into Thanksgiving Week. * IMPACTS...Such rain amounts will greatly increase the risk of flooding, especially for the northern half of the area where soils have already been saturated by previous rain events. Expect flooding on in low lying areas, areas with poor drainage, and increased risk of debris on roadways. Rivers, streams and creeks will rapidly rise. The Eel River is around 20 percent chance of exceeding flood stage Thursday evening. The Mad River and the Russian River are showing 5 to 10 percent of reaching flood stage. * Stay tuned to the weather forecast over the next couple days as forecast confidence and details will likely increase. Beyond rain, this storm is also expected to bring widespread damaging wind.
