AREA FORECAST DISCUSSION...UPDATED
National Weather Service Eureka CA
610 AM PST Tue Dec 24 2024

.SYNOPSIS...Series of atmospheric river storms will bring
a risk for flooding, strong winds and dangerous surf through
the weekend.

&&

.DISCUSSION...Cold front has been producing heavy rain through
the night with 12 hour totals ranging from 2 to 4 inches. Frontal
band will shift southeastward by mid morning with heavy rain rates
diminishing by noon. Instability trailing behind the boundary may
result in locally heavy downpours by late morning and early afternoon.
A break in the precip is expected by mid this evening, though a
few showers may continue to push onto the North Coast. Activity
is forecast to wind down by late evening with warming aloft. Warm
frontal precip ahead of the next shortwave will approach the
North Coast Wed AM. Precip will be quite light on Wed; sprinkles
or a few hundredths for mostly Del Norte and northern Humboldt.
Otherwise, main hazard will be patches of fog in the interior
valleys. Surface pressure gradients tighten through the day on
Wed. 925mb 60kt jet develops Wed night in advance of the next
frontal boundary and a wind advisory will be necessary for Del
Norte and Humboldt Counties. ECMWF ensemble indicates 50mph or
more for the Del Norte Coast, and 40 mph or so around the Humboldt
Bay area and Eel Delta. Higher elevations and ridges of Humboldt
will no doubt gusts to 50 mph or more. Even NBM has peak wind
gusts to 45-55 mph along the coast. Rates of surface pressure
falls may support a high wind warning for the Del Norte coast.
Instability increases Thu morning and robust convection or TSTMS
may develop near the coast and offshore over the waters.

Parade of atmospheric river storms will continue Thu night into
Sunday. Each storm will most likely generate strong winds and
heavy rain. Potential for flooding will increase over the
weekend. The exact magnitude of the flooding is not clear. Looking
at the ECMWF and WPC guidance, Sunday may be the day with the
greatest threat of flooding. ECMWF ensemble is wetter than the
GEFS with a wavy frontal boundary aimed at the northern portion of
the forecast area. We should finally see a break in the heavy
rain on Monday after passage of a large scale trough. DB

&&

.AVIATION...After the heavy rain overnight, flight conditions are
expected to improve by the afternoon. Lingering effects of heavy
downpour could result in some ground fog this morning, but not
enough radial cooling will develop before the daylight hours to
impact flight categories. That said, MVFR/VFR conditions will
prevail at the coastal terminals after the cold sector passes later
today. Wind direction will veer from southwesterly to northerly by
this evening before returning to southerly by Christmas morning,
accompanying Santa's sortie. Light rain and ceilings around 2500ft
are expected through the current TAF period. Overcast skies with
ceilings around 5000 ft will last through the evening at KCEC and
KACV and a return of southerly winds. Similar conditions at KUKI
with light rain and light winds with mostly VFR categories through
the TAF period. /EYS

&&

.MARINE...Winds have eased in the wake of the front. There is slight
potential for thunderstorm development through the morning,
especially south of Cape Mendocino. A large long period westerly
swell around 20 feet continues to move across the area waters. The
swell will continue to slowly subside through Wednesday. The storm
cycle will remain very active through the remainder of the week with
additional frontal systems producing strong southerly winds and and
steep southerly waves, along with large long period westerly swells.

&&

.HYDROLOGY...The next rounds of rain look to be more persistent
with shorter breaks of no rain in between each IVT maximum. This
has the potential to cause more significant flooding in Del Norte,
Humboldt and Mendocino counties. Portions of northern Lake county
may see some heavy rain, but in generally rainfall amounts will
be less in Lake county. The CNRFC ensemble hydrographs indicate a
45 percent chance for the Eel River at Fernbridge to exceed minor
flood stage of 20 ft by Sunday evening. Stay tuned. DB

&&

.BEACH HAZARDS...Large waves will continue to slowly subside this
morning, with breaker waves from 20 to 22 feet lasting into the
afternoon. Another swell train is expected Thursday morning with
similar wave dimensions and resulting beach oriented surf around 20
to 23 feet, lasting well into Sunday with a brief lull late Thursday
night. Large breaking waves along the coast will lead to increased
wave run-up on beaches with waves topping and washing over large
rocks and jetties. These large waves can be erratic and
unpredictable, and will be capable of sweeping people into the
frigid and turbulent ocean water. In addition, mariners traversing
the bar are urged to exercise extreme caution or stay in port until
the threat subsides.
