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 Nov 22, 2:53 PM PST, 4 minutes earlier.

Area forecast discussion, Nov 22, 2:53 PM PST, 4 minutes before
AREA FORECAST DISCUSSION
National Weather Service Eureka CA
253 PM PST Sun Nov 22 2020

.SYNOPSIS...A series of weak fronts will bring periods of light
rain mainly north of Cape Mendocino through Wednesday. Dry
weather will return late in the week. Large surf will build on
Wednesday and Thursday.

&&

.DISCUSSION...A shortwave trough and an attendant weak surface front
are located just off the NW California coast this afternoon. This
system will move across the area this evening and bring a round of
light rain to Del Norte and northern Humboldt Counties, with a few
showers possible as far south as the Mendocino Coast. Expected
rainfall amounts through Monday morning should generally remain
below a tenth of an inch for most of the area, perhaps slightly
higher across Del Norte County. Showers will taper off by late
Monday morning across most of the area, yielding a period of dry
conditions through much of the day on Tuesday as transient short
wave ridging moves overhead. Another weak frontal system will then
clip the area with some light rain late Tuesday into Wednesday,
likely with very similar results to the current system. High
pressure will be back in control by Thursday, ushering in another
dry period with colder mornings through next weekend. There looks to
be some potential for another round of precipitation towards the
beginning of next week. /CB

&&

.AVIATION...By late morning, the first light showers from a weak
front were in the VC of the coastal terminals of Humboldt and Del
Norte county, with some brief periods of IFR observed at KACV.
Ceilings are expected to come down to MVFR overnight, with TEMPO
periods of IFR through the early morning hours. Drizzle to perhaps
light rain will move in after sunrise tomorrow, continuing into the
early afternoon with opportunity for TEMPO MVFR ceilings. Light
winds will prevail through the period. There is a chance for some
lower clouds/moisture with some periods of MVFR ceilings potentially
getting into KUKI overnight, with low confidence given how dry the
airmass has been there.

&&

.MARINE...Winds and seas have been on the decline today as a quickly
passing weak front has temporarily disrupted the northerly wind
generating pressure gradient. Northerlies will quickly fill back in
this evening, focused mainly in the southern waters. This pattern
of quickly passing fronts with bursts of reinvigorated northerlies
will persist through mid week. A mid period northwest swell has
begun filling into the waters this afternoon, to build to around 11
feet at 14 seconds by around late afternoon tomorrow. This will
contribute to somewhat chaotic sea states, especially in the
southern waters where significant wave heights may reach 13 feet.
Went ahead with Small Craft Advisories given the duration of wave
heights above 10 feet. Attention then turns to the potentially very
large swell expected to move through the waters during the middle to
later parts of the week. See the Beach Hazards section below for
more details.

&&

.BEACH HAZARDS...Wave guidance continues to show a large, long-
period NW swell moving through the waters Wednesday and Thursday.
Hazardous surf conditions with breaking waves around 25 feet will be
possible along NW facing beaches. The forecast has been consistent
for several days, and a High Surf Advisory will likely be needed.
