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 Honolulu, HI wrote its last area forecast discussion before this small craft advisory went out at Oct 3, 8:21 PM HST, 7 hours 2 minutes earlier.

Area forecast discussion, Oct 3, 8:21 PM HST, 7 hours 2 minutes before
Area Forecast Discussion
National Weather Service Honolulu HI
821 PM HST Sun Oct 3 2021

.SYNOPSIS...
Moderate to occasionally breezy trade winds will continue through
the first half of the week, with clouds and showers favoring
windward and mauka locations. An upper disturbance will support
better windward shower coverage the next couple of days,
especially over Kauai and Oahu. Trade winds are expected to
strengthen beginning Wednesday, with windy conditions possible by
the end of the week and upcoming weekend.

&&

.DISCUSSION...
Guidance remains in decent agreement and depicts showery
conditions continuing through the first half of the week over the
western end of the state due to a combination of an upper trough
extending southward into the area and a decent sized area of
higher moisture moving through. Observations at the gages around
the state reflect this, with 24-hr accumulations (through 7 PM HST
this evening) ranging from 2 to 4 inches over Kauai and a quarter
to half of an inch on Oahu. For the eastern end of the state,
more of a stable trade wind pattern has limited accumulations.
Upper air soundings earlier this afternoon reflected this pattern
with more instability/lack of an inversion shown at Lihue
(saturated up to ~10 kft with a PW around 1.8 inches). The
opposite was shown at Hilo, where plenty of dry air along with a
typical subsidence inversion were depicted. Models and ensembles
project a tightening pressure gradient by or around midweek, that
supports locally strong trades through the upcoming weekend. Some
drier air is shown moving in from the east, which should limit
windward shower coverage into the second half of the week.

&&

.AVIATION...
Moderate to occasionally breezy trades will persist across the
island chain through Monday. Slight atmospheric instability
combined with enhanced moisture is expected to remain across the
western end of the island chain through early Monday morning. This
will result in low clouds and frequent showers across Kauai and
Oahu, which will likely keep periods of MVFR low ceilings and
reduced visibility in heavier showers over windward sections of
these islands. For the remaining islands, expect a more typical
trade wind distribution of low clouds and showers concentrated
along windward facing coasts and slopes. This may result in brief
periods of MVFR conditions overnight.

AIRMET SIERRA is in effect for mountain obscuration along north
through east facing sections of Kauai and Oahu above 2 thousand
feet for due to the low clouds and showers. This AIRMET may need
to be added to the higher terrain of additional islands later
tonight.

&&

.MARINE...
High pressure north of the Hawaiian Islands will continue to
produce moderate to fresh trade winds over the coastal and
offshore waters into Tuesday. Trade winds will likely strengthen
from Wednesday into the weekend, as a stronger high builds in
north of the region.

Small surf along north facing shores tonight will get a boost from
a small, long-period west-northwest swell generated by Typhoon
Mindulle. This swell will spread into Oahu and Maui County
Tuesday through Thursday, then diminish on Friday. Small south
swells will keep surf from going flat along south facing shores
through much of next week. A slightly larger south swell may
elevate surf heights from Friday into next weekend. East shore
surf will hold fairly steady through Tuesday. Strengthening trades
over and upstream of the islands will build surf heights along
east facing shores from late Wednesday into next weekend.

&&

.HFO WATCHES/WARNINGS/ADVISORIES...
None.
