What forecasters said that day

The local office's own words before this wind 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 wind advisory went out at Mar 31, 1:45 AM PDT, 11 hours 20 minutes earlier.

Area forecast discussion, Mar 31, 1:45 AM PDT, 11 hours 20 minutes before
AREA FORECAST DISCUSSION...CORRECTED
National Weather Service Eureka CA
145 AM PDT Tue Mar 31 2026

.SYNOPSIS...A weakening frontal system continues the chance for rain
showers through Tuesday. Widespread rain is expected late Tuesday
night into Wednesday followed by lingering showers into Thursday.
Mountain snow and coastal small hail is possible Wednesday night
and Thursday morning.

&&

.DISCUSSION...Light rainshowers have arrived to the area, with a band
of precip. focused primarily on northern Humboldt and Del Norte. Rain
rates have remained light to locally moderate in mountainous terrain.
High resolution models show showers mainly for Del Norte, Humboldt,
and Trinity counties, though a few isolated showers are still possible
for Mendocino and Lake. These showers are likely to remain light,and
little to no impacts are expected.

A stronger frontal system moves through the PacNW Tuesday night through
Wednesday. Southerly winds will increase ahead of the main frontal
passage Wednesday morning. Much of elevated terrain of Del Norte and
the higher terrain in Humboldt have over 50% chances to see gusts over
40 mph. Localized gusts of over 50 mph are possible over the highest
terrain. Lake County may also see strong gusts, with a broad 20% chance
for gusts over 40 mph at lake level. The higher elevations, including
the Cobb area, have much higher probabilities.

Widespread light to moderate rain is likely across the area. Periods
of heavy rain are possible for the North Coast, and especially in the
King Range and the mountains of Del Norte and northern Humboldt. Total
rain amounts range from around 2.0-3.0" in Del Norte, 1.0-2.0" in Humboldt
and Trinity Counties, and 0.25-1.00" in Mendocino and Lake Counties.
This will largely be beneficial rain, but some minor impacts (flooding
in poor drainage areas and mud/rock slides) are possible in Humboldt
and Del Norte with the heaviest rain. Snow levels will drop with this
system, down to 5,000-5,500 ft Wednesday morning during the period
of most precipitation. This will bring some snow down to Scott Mountain
Pass. Snow totals there range from around 3 to 6 inches, depending
on how low snow levels drop.

Snow levels continue to drop into Thursday, and could be as low
as 2,500 ft as stratiform rain turns showery. While precipitation
is likely to be meager by this point, some light snowfall is possible
on the highest passes of Highways 3, 36, 199, and 299. A Winter
Weather Advisory has been issued for the Trinity Horn above 4000ft
due to melted snow freezing overnight while snow level plummet,
creating icy, hazardous roads.

Additionally, with much colder air aloft, atmospheric instability
will increase, particularly along the coast. Showers capable of
producing accumulating small hail are possible, along with
isolated thunderstorms. Much cooler temperatures are expected
Friday morning with widespread near-freezing or freezing
temperatures. Temperatures will generally trend warmer as high
pressure begins to rebuild into the weekend. JB

&&

.AVIATION...(31/06Z TAFs)...VFR conditions with mid- to high-levelclouds
prevail across all TAF sites. Nevertheless, there is the potential
for MVFR ceilings with VCSH for the coastal terminals from 31/07Z through
31/21Z. CAMs suggest there will be an increase of showers activity
from 15Z through 20Z. Meanwhile, mostly VFR conditions in UKI through
20Z, before ceilings lowering to MVFR. Another frontal system will
bring an increasing chances of precipitation after 01/05Z for all TAF
sites. /ZVS

&&

.MARINE...Northerly winds continue to diminish overnight, before becoming
northwest to west winds early Tuesday. Winds will shift to southerly
Tuesday afternoon and strengthen Tuesday night through Wednesday as
a front approaches from NW. Winds are expected to peak to strong to
near-gale south winds across the northern waters Wednesday morning,
while mostly moderate breezes flow over the southern waters.
Isolated gale force gusts are possible near PT St George by
Wednesday morning. Robust westerly winds will rapidly develop
behind the front Wednesday afternoon and then shift to northerly
early Thursday.

Seas will continue to subside through Tuesday morning as northerly winds
diminish. Seas will remain below 5 feet through Tuesday night, before
a period of steep wind waves builds on Wednesday in the northern waters.
A large steep northwest swell will begin to build in Wednesday night
and peaking to around 10-14 feet at 12 seconds on Thursday. /ZVS
