What forecasters said that day

The local office's own words before this hazardous seas 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 hazardous seas warning went out at Aug 25, 2:59 PM PDT, 12 hours 35 minutes earlier.

Area forecast discussion, Aug 25, 2:59 PM PDT, 12 hours 35 minutes before
AREA FORECAST DISCUSSION
National Weather Service Eureka CA
259 PM PDT Tue Aug 25 2020

.SYNOPSIS...Isolated thunderstorms are possible over portions of
Trinity County this afternoon and Wednesday afternoon, with
seasonably hot conditions returning late this week for interior
valleys while marine cloudiness persists at the coast.

&&

.DISCUSSION...As of this afternoon the stratus is slowly eroding at
the coastline, though some areas may not fully clear out before
dusk, particularly along the Mendocino coast. Elsewhere cumulus is
forming over the mountains of Trinity, eastern Mendocino, and Lake
counties. There may be just enough instability this afternoon to
trigger an isolated shower or storm, but otherwise dry conditions
should persist today. Of greater note is that the clear skies and
unstable atmosphere has allowed fire activity to become a bit more
active in far northern Lake County.

A passing upper trough will bring another shot of mountain storms in
the same areas Wednesday afternoon. This trough though may be enough
of a trigger to help force upward motion and give a better
opportunity for an isolated storm over two in Trinity or far
northeastern Mendocino counties. The Storm Prediction Center has
placed the far northeastern portion of Trinty County in their slight
dry thunderstorm risk area. But with storms anchored by the
terrain the dry lightning risk will be much less of a concern than
a few days ago.

As for temperatures, coastal areas will remain cool with stratus
each morning at least for the next few days while interior areas
gradually warm up as ridging builds over the west behind the
departing trough. There may be several areas across the interior
that are back near 100 degrees by Friday into the weekend and early
next week. /RPA

&&

.AVIATION...Conditions have been generally improving this afternoon
at the coastal aerodromes. A low level eddy south of Pt St George
has kept LIFR ceilings locked-in over KCEC through the afternoon
hours, however. LIFR conditions with ceilings below 500 feet and/or
vsbys less than 1SM are expected to impact the coastal terminals
again this evening and overnight. How quickly LIFR conditions reform
is not certain. For now will follow the HREF and statistical
guidance which has it developing later tonight into early Wednesday
morning. After LIFR conditions again Wed morning, conditions are
expected to slowly improve again Wed afternoon. Also, smoke from
nearby wildfires will continue to produce periods of MVFR to IFR
vsby/sky obscurations at KUKI through the forecast period.

&&

.MARINE...Northerly winds will increase through the week, with gale
force conditions expected over the outer waters through the weekend.
A gale warning has been hoisted for northern outer waters where low
end gales are expected Wed afternoon and evening. Winds will
increase toward the latter portion of the week and over the weekend
as a thermal trough builds along the coast and high pressure
strengthens offshore over the NE Pacific. GEFS indicates high
probabilities of gale force winds outside 10nm north of Cape
Mendocino over the weekend. The ECWMF ensemble indicates lower
probabilities, however ENS mean 1000mb winds increase to over the
97.5th percentile late in the week and into the weekend across the
outer waters. Thus, will hoist the gale warning now and run it
through the weekend. Winds nearshore will generally be lighter,
however locally stronger winds with gusts around 40 kt will be
possible around Pt St George and downwind of Cape Mendocino toward
the latter portion of the week and over the weekend. Seas will
increase and grow steeper through the week and this weekend. A
hazardous seas warning may be needed for the northern inner waters
if winds offshore (20-60NM from shore and upstream) reach full
gale.

&&

.EKA WATCHES/WARNINGS/ADVISORIES...
