Hydrologic Outlook
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.

Coastal Flood Watch
* WHAT...For the Coastal Flood Warning, High astronomical tides
and large surf will cause moderate flooding in low lying areas
around Humboldt Bay Coast. Up to one foot of saltwater
inundation above ground level is possible in low lying areas
near shorelines and tidal waterways. Between 9.3 and 9. 6 feet
MLLW at the north spit tide gauge is predicted. For the Coastal
Flood Watch, High astronomical tides may cause moderate to
locally major flooding in low lying areas along the Redwood and
Mendocino Coast. Up to 1.5 foot of saltwater inundation above
ground level is possible in low lying areas near shorelines and
tidal waterways. Tides may exceed the highest astronomical tide
on record at the North Spit tide gauge during the morning high
tides on Friday and Saturday.
* WHERE...Northern Humboldt Coast County.
* WHEN...For the Coastal Flood Warning, from 7 AM to 11 AM PST
Thursday. For the Coastal Flood Watch, from Thursday morning
through Saturday afternoon. High tide is at 8:08 am at the
Humboldt Bay North Spit tide gauge. Saltwater inundation will
be possible 1 to 2 hours before and after high tide.
* IMPACTS...Several coastal roads may be closed. Low lying
property and some critical infrastructure will be inundated.
These impacts will include, but not limited to, roadways in
King Salmon and the Arcata bottoms. Shoreline erosion will
occur.
