What forecasters said that day

The local office's own words before this river flood warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Eureka, CA wrote its last area forecast discussion before this river flood warning went out at Dec 30, 5:37 AM PST, 3 hours 52 minutes earlier.

Area forecast discussion, Dec 30, 5:37 AM PST, 3 hours 52 minutes before

AREA FORECAST DISCUSSION
National Weather Service Eureka CA
537 AM PST Fri Dec 30 2022

.SYNOPSIS...Rain continues through Saturday with heavier rain rates
in the southern portions of the area. This afternoon gusty winds
will occur on exposed ridges south of Highway 299. Drier weather
will arrive Sunday for a brief dry spell with more rain, snow and
wind next week.

&&

.DISCUSSION...Our CWA will have continuous stratiform rain for the
next 24 hours. A plume of moisture over the NERN PAC will continue
to move the area with IVT values in the 700 kg/m/s range. This is a
warm airmass which explains the snow levels above our highest
mountain passes. This will change by the end of the weekend as snow
levels begin to lower, Saturday evening. Precipitation will also
trail off by Saturday evening which keeps the possibility of snow
isolated to higher elevations near the Scott Mountains and Yolly
Bollys'. THe long duration of precipitation will warrant areal flood
watches to continue through Saturday afternoon for most of the CWA.
Local rainfall amounts over 6 inches is possible. Also, southerly
winds gusting up to 50 mph or more are expected in southern
Humboldt, southern Trinity, Mendocino interior and Lake county.
Exposed ridges and elevations will reach advisory level criteria of
45 mph Friday afternoon and ease Friday night. Otherwise, a dryer
regime will enter the area by Saturday evening. This will be a be
brief reprieve from recent wet and wintry weather Monday morning as
precipitation returns. This will bring lower snow levels in eastern
Trinity county, possible to around 2500 feet.

Later next week, models are signaling a deep low pressure system
that could bring more adverse weather to the area. Confidence is low
as to timing and location. /EYS

&&

.Aviation...A deep layer of moisture and onshore flow is bringing
moderate rain and IFR or LIFR conditions in most areas. Generally
rain is expected to keep the CIGS low through the day and into
tonight, although there may be some short periods of improvement.
Tonight conditions may start to slowly improve at KCEC towards
morning as the heavier precip drops south. KUKI may see some
improvement this afternoon and evening until the heavier precip
shifts south again late tonight. KACV is expected to remain in the
heart of the precip through tonight and may not see much
improvement. A compact surface low is expected to bring strong
southwest winds to KACV and KUKI. These will mainly be aloft so have
added some wind shear for this afternoon. MKK

&&

.Marine...The main area of concern today is a small compact surface
low that is expected to bring near gale or gale force southwest
winds today. Winds will likely increase rapidly this morning. Most
models are showing the stronger winds remaining south of Trinidad
Head. There is a lot of uncertainty on the placement of this low so
I went ahead and issued a gale warning for the northern waters.
Coverage may be limited to the southern third of the zone, but a
small shift north would make a big difference. More uncertainty
remains on whether these will make it into the inner zones so have
left them out of the warning. This afternoon a northwest swell also
builds into the waters to around 9 feet at 12 seconds. This swell
generally persists through the period around 8 to 12 feet at 12 to
15 seconds.

Saturday northerly winds rapidly increase and may see gusts of 30
kt.  Sunday morning these will diminish becoming southerly again.
Once again it will likely be close to gale force. Southerly winds
are then expected to persist through much of the week. Models are
trying to resolve a very strong area of low pressure Wednesday or
Thursday. This has the potential to bring storm force winds to the
waters. MKK

&&

.HYDROLOGY...An atmospheric river will impact Northwest California
Friday into Saturday morning. Rainfall totals will range from 4
to 7 inches across west-southwest facing terrain, while valleys
and coastal plains experience totals from 2 to 4 inches. Heavy
rainfall will increase the potential for urban and small stream
flooding. In addition, rapid rises are expected on rivers, with
flood stage expected to be reached on the Eel River at Fernbridge,
and the Russian River near Hopland during Saturday.
