What forecasters said that day

The local office's own words before this gale 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 gale warning went out at Jan 19, 5:05 AM PST, 8 hours 53 minutes earlier.

Area forecast discussion, Jan 19, 5:05 AM PST, 8 hours 53 minutes before
AREA FORECAST DISCUSSION
National Weather Service Eureka CA
505 AM PST Sun Jan 19 2020

.SYNOPSIS...High pressure will allow for dry weather today, with
even some filtered sun through high clouds. A cold front will
bring widespread rain and high elevation snow Monday night into
Tuesday, with additional episodes of showery weather possible
through the rest of the week.

&&

.DISCUSSION...Today looks to be mostly dry with a broad ridge and
slightly warmer temperatures and increasing mid and high
cloudiness through the day. Still, there will be some filtered
sunshine at times.

A more significant storm system is forecast to approach the area
from the NW late Monday, but most precipitation is expected to
hold off until late afternoon or evening. Precipitation will be
more widespread, ranging from just less than 2 inches in the Del
Norte mountains to about half an inch over far southern Mendocino
County. Snow levels with this system will start out around 5000 ft
but will drop below 4000 ft by Tuesday night. As a result, some
decent high elevation snow accumulations are expected, with over
one foot of snow possible in the highest terrain of N Trinity and
E Del Norte counties.

An active but progressive weather pattern will continue to result
in frequent bouts of precipitation in the coming week, but there
are indications that an upper ridge will develop over the W coast
late in the week, possibly bringing high temperatures over 60
degrees. /SEC

&&

.AVIATION...Winds will be much lighter today. As a result, expect
shallow mist this morning and haze late this morning and this
afternoon at the coastal terminals. Except for the above mentioned
mist/haze and patches of fog and low clouds in the interior
valleys, VFR with high cirrus clouds is expected today. Conditions
will generally remain VFR tonight, but with highly variable and
difficult to forecast shallow mist at the coastal terminals. Fog
and low clouds will also be possible in the interior valleys under
mid and high cloud decks with light or calm surface winds.

&&

.MARINE...Westerly swell will create hazardous seas today. The
swell has been running higher at all the nearshore buoys compared
to the forecast from the NWPS model. Suspect the swell may not
subside as quickly as the model indicates tonight. Thus, the small
craft advisory for hazardous seas has been extended into this
evening. Seas should subside more substantially Monday morning.
The NWPS continues to indicate a rapid increase in short period
southerly waves again on Monday, which is likely overdone. This is
a known bias. Southerly winds and wind waves will increase more
substantially Monday evening and overnight as stronger southerlies
increase to gale in the northern waters. The highest probability
for gales will be in the northern outer waters. Confidence is
lower across the inner waters. How quickly winds die down is also
not certain. Strong winds may linger into Tuesday morning south of
the Cape as the NAM-nest indicates. Most all the models have the
winds dropping off and switching to the SW after frontal passage
Tuesday morning. A large westerly swell from 18-20 ft is expected
to build later in the day on Tuesday. The swell will pose a threat
for beachgoers and mariners traversing harbor entrances. The most
likely period for high surf appears to be during the afternoon
and evening hours. An advisory for surf or a beach hazard
statement will need to be considered over the next 24-48 hours.
Winds and seas should quite down around mid week, however a longer
period westerly will build toward the end of the week, bringing
another threat for large breaking waves to the beaches.

&&

.BEACH HAZARDS...Large W swell is forecast to build across the
waters late Tuesday. As a result, dangerous surf conditions are
possible with surf heights over 20 ft. /SEC

&&

.EKA WATCHES/WARNINGS/ADVISORIES...
CA...None.
NORTHWEST CALIFORNIA COASTAL WATERS...
     Gale Watch from Monday evening through Tuesday morning
      for PZZ450-470.
     Small Craft Advisory until 9 PM this evening
