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 Oct 18, 1:13 PM PDT, 9 hours 32 minutes earlier.

Area forecast discussion, Oct 18, 1:13 PM PDT, 9 hours 32 minutes before
AREA FORECAST DISCUSSION
National Weather Service Eureka CA
113 PM PDT Sat Oct 18 2025

.SYNOPSIS...Mild warming and drying will continue today with
coastal areas slower to clear out. Cooler weather and very light
coastal rain is expected Sunday morning with warmer weather again
early next week with wetter weather by next weekend.

&&

.DISCUSSION...Transient high pressure peaks across the area
today, allowing for the hottest interior valleys to reach near
80. A weak, shallow marine layer will persist along the coast with
stratus eroding at a slow rate. HREF and observations show
lingering low clouds at the coast at least until the late
afternoon. An incoming front will push low level clouds and
moisture onto the coast around 10-12z, early Sunday morning.
Initial model runs had greater precip accumulation which has
trended down considerably. Most of the light rain is expected to
fall in Del Norte 0.05-0.08 inches and even less on the coast,
confined to areas north of Cape Mendocino.

Weak high pressure and slight warming will likely reassert
itself early next week, though low pressure passing to the
southeast will limit the amount of warming with only a moderate
chance (50%) of some highs even over 80. Strong offshore flow
around the low will likely help better dry conditions compared to
the currently high stubborn dewpoints. Widespread patchy frost
will be likely (60% chance) Monday morning, especially in Trinity
County.

There is increasing confidence in long range forecasts that a
significant rain event will impact the area late next week. Though
high uncertainty remains, NBM already places a 95% chance of wetting
rain all the way along the North Coast with an 70% chance of 3 day
rainfall over 3 inches and a 25% chance of 3 day rainfall over 5
inches. Despite these high totals form the NBM, ensemble spreads
remains very large, indicating great potential for lower end
scenarios to still be realized. On the stronger end, such an event
would likely be accompanied by strong wind with such rainfall
amounts capable of moderate flood impacts. /JHW /EYS

&&

.AVIATION...18Z TAFS...Coastal stratus has socked in along the
Redwood coast today. HREF, NAMNest, and LAMP models shows minimal
clearing for the rest of the day. KCEC shows a higher chance of
clear skies before a coastal eddy fills the skies again this evening
with fog potential. A weak front is expected to pass through the
area between 11Z-17Z tomorrow morning. Periods of rain are possible
for Humboldt and Del Norte counties with degraded visibilities and
low clouds. Conditions should clear and calm by 18Z tomorrow if high
resolution models are correct. Inland, VFR is expected with light
winds and minimal impacts from the frontal passage outside of the
North Coast. Frontal passage impacts can include mountain waves and
orographic clouds near terrain. /ds

&&

.MARINE...A long period northwest swell is building across the
waters through the day, and peaking to 9-11 feet at 16 seconds this
afternoon. Tonight into the morning, southerly winds will developed
briefly across the outer waters as a weak frontal system moves
through. Northerly winds increase again tomorrow afternoon and
strengthening through early next week. Gale strength gusts are
forecast around and south of Cape Mendocino Sunday afternoon through
Sunday night. A Gale warning has been issued for the southern outer
waters from 5PM Sunday - 11AM Monday.

A second larger swell move in late Sunday through Monday. Breakers
may reach 20 feet through that period. Additional large swells are
then likely through next week with an active Pacific storm track.

Northerly winds will remain somewhat strengthened into mid next
week. The northerly wind pattern breaks down thereafter as a strong
trough takes aim at the vicinity of N CA. Strong southerly winds are
possible Thursday or Friday if this system take a more southerly
track. Chances for at least sustained gale strength southerlies and
large surf continue to increase through the coming weekend with
models showing a signal for additional cyclones. /ds
