Hydrologic Outlook
National Weather Service Eureka CA
257 PM PST Tue Dec 30 2025
...Periods of heavy rain and an increased risk for flooding
Friday into this weekend...
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.
