What forecasters said that day

The local office's own words before this small craft advisory 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 small craft advisory went out at Feb 3, 5:10 AM PST, 9 hours 59 minutes earlier.

Area forecast discussion, Feb 3, 5:10 AM PST, 9 hours 59 minutes before
AREA FORECAST DISCUSSION
National Weather Service Eureka CA
510 AM PST Sun Feb 3 2019

.SYNOPSIS...An upper disturbance will approach the area today,
bringing an increase in shower activity. A cold storm system
will drop south along the coast on Monday, bringing much lower
snow levels, more showers, and the potential for small hail.
Drier weather will return by Tuesday, with more rain and snow
expected by the end of the coming week.

&&

.DISCUSSION...After some brief ridging over the area overnight
with a lull in precipitation, rains are once again increasing in
coverage and intensity offshore as a disturbance drops SE toward
the region. This precipitation will spread over the land areas by
later this morning and this afternoon. Snow levels will lower
significantly through the afternoon and evening. Some modest
instability may be enough to allow a few thunderstorms to develop
this afternoon and evening, mostly S of Cape Mendocino.

A more significant upper low will drop S along the Pacific Coast
tonight and Monday. This feature will bring continued shower
activity and allow even colder air to filter into the area. On
Monday, snow levels are expected to drop to around 1000 feet over
the N half of the area and closer to 2000 feet over the S. Snow
levels will likely lower further into early Tuesday. This will
bring widespread snowfall to much of the area above 1000 ft and
the potential for at least snow mixed with rain to lower
elevations along the Redwood Coast. Heavier showers will have the
potential for mixing the snow level closer to the surface, as
well as producing small hail. Motorists across the area should
continue to monitor the forecast.

Drier weather is expected by Tuesday, with some lingering showers
over the interior mountains. Wednesday and Thursday are expected
to be dry, with rain and showers returning by Friday and
Saturday. /SEC

&&

.AVIATION...Bands of showers pin-wheeling around a cold upper
low offshore the Pacific NW coast will impacts the terminals
today through tonight with periods of MVFR ceilings and vsbys.
Brief IFR and gusty west to northwest winds will be possible in
heavier showers. Small hail and isolated low top thunderstorms will
be also be possible at north coast terminal late tonight as freezing
levels fall to 1500 feet.

&&

.MARINE...Combined seas early this morning were still running over
10 ft due to a combination of three wave groups. The advisory for
hazardous seas has been extended through at least 8am. All three
wave groups are forecast to steadily subside today, with significant
wave heights falling below 10 ft by mid morning. Seas will continue
to trend downward tonight and bottom out early Monday morning.
Models continue to indicate a N-NW wind surge developing on Monday
behind another front that will drop down from the NW. The main
thrust of strong N-NW winds appear to remain just outside NW
California coastal waters, beyond 60NM. Short period NW swell will
start to build on Monday as a result of this wind surge. 18+ ft seas
with short periods will be possible depending on the GFS wind fields
offshore. Confidence is high we are going to see a ramp up in seas,
just how large is not certain at this time due to the complex
evolution of the offshore storm.

&&

.BEACH HAZARDS...Tidal anomalies are running about 1.5 feet above
predicted values once again this morning at N Spit this morning.
The next high tide at N Spit will be at 1025 AM this morning, and
we will probably need another Coastal Flood Advisory for minor
coastal flooding. Will continue to monitor early this morning.
