Hydrologic Outlook issued December 30 at 2:57PM PST by NWS Eureka CA

Effective: Tue December 30, 2025, 2:57 PM
Expires: Thu January 1, 2026, 10:00 PM

ESFEKA A series of atmospheric rivers will bring an increased risk for urban and small stream flooding late this week and into this weekend. The first round of rain will arrive Wednesday night into Thursday and provide generally light to moderate rainfall amounts. Locally heavy rain is expected in the King Range. This initial period of rain will set the stage for a more intense rainstorm expected to arrive Friday into Friday night. Current indications are for the heaviest rainfall to occur during the day on Friday into Friday night. The greatest risk for small stream flooding will occur during this time period and probably continue into Saturday after heavy rain has ended due to the lag in rainfall run-off. Road closures will be possible. At this point, the area of greatest concern is in southern Humboldt and northwest Mendocino counties. Small rivers, streams and creeks such as Elk river, Jacoby creek and Mattole river could exceed their banks and flood area roads. Southern Mendocino and Lake counties may also experience heavy rain and road flooding will be possible. Mainstem rivers will also likely rise sharply and will need to be monitored for possible flood stage exceedance. Be on the lookout for watches, advisories and warning as this next heavy rain event unfolds. Plan to avoid driving through areas that tend to flood.

* WHAT...High astronomical tides and large surf may cause moderate to locally major flooding in low lying areas along the Mendocino Coast. Up to 1.5 foot of saltwater inundation above ground level is possible in low lying areas near shorelines and tidal waterways. * WHERE...Coastal Del Norte, Southwestern Humboldt and Mendocino Coast Counties. * WHEN...From Thursday morning through Saturday afternoon. . * IMPACTS...Several coastal roads may be closed. Low lying property and some critical infrastructure will be inundated. Some shoreline erosion may occur.

A Coastal Flood Watch means that flooding is possible but not imminent. Coastal residents in the watch area should begin preparations for rising water and take appropriate action to protect life and property. Feet Above Ground is locally defined as feet above the Highest Astronomical Tide or HAT.
