What forecasters said that day

The local office's own words before this gale warning 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 gale warning went out at Feb 25, 8:37 PM HST, 6 hours 28 minutes earlier.

Area forecast discussion, Feb 25, 8:37 PM HST, 6 hours 28 minutes before
Area Forecast Discussion
National Weather Service Honolulu HI
837 PM HST Sun Feb 25 2018

.SYNOPSIS...
A very moist atmosphere combined with a trough aloft moving
overhead will maintain heavy showers and isolated thunderstorms
over Kauai and Oahu overnight. Mostly cloudy skies with passing
showers can be expected across Maui County and the Big Island.
High pressure will build in northeast of the area this week with
generally drier weather expected. Showers will tend to favor
windward and mauka areas. Rather breezy to locally windy
conditions can be expected toward the middle of the week as the
high moves closer to the state.

&&

.DISCUSSION...
Heavy rains flared up across windward Oahu during the late
afternoon, with the focus of heavy shower activity shifting over
the urban core of Honolulu during the early evening. Rain
intensity has diminished across the island during the past half
hour. Flash flooding has been reported across parts of Oahu, with
very high water levels observed on several streams. A few rumbles
of thunder have been heard on Oahu as well. A Flash Flood Warning
remains in effect until 915 PM to cover this ongoing event.
Elsewhere across the state, scattered to numerous light to
moderate showers prevail.

Surface analysis shows a weak trough over the Northwestern
Hawaiian Islands, with a strong high centered far to the NNE of
the state. Brisk ESE flow prevails between these features over the
islands. Aloft, a deep mid/upper level trough remains west of the
state, with shortwaves evident in water vapor imagery rotating
through the trough. MIMIC-TPW imagery and the 00Z soundings
depict a very moist environment over and around the islands, with
PW values ranging from 1.7 to almost 2 inches.

Overnight, expect active weather to continue over Oahu and
possibly Kauai, where the deep moisture in place is closest
to the upper trough. Short-term radar trends suggest that the
greatest risk for additional flooding during the next few hours
may be over Oahu, and will need to look at expanding the Flash
Flood Watch to cover Oahu for the rest of the night, as this
current round of flooding may not be the last for this event. We
have already updated the forecasts to keep mention of heavy rains
and isolated thunderstorms through the remainder of the night for
Kauai and Oahu. For Maui County and the Big Island, expect
scattered to numerous showers but lower potential for any heavy
rains or flooding.

Models remain in good agreement with the weather pattern for the
upcoming week, with a transition to drier and stable conditions
expected. The upper trough to our west weakens during the next few
days, while the blocking mid/upper level ridge that has been
parked northeast of the state for the past several weeks shifts
westward and closer to the islands. This will bring an
increasingly stable airmass over the islands, with significant
drying occurring in the mid levels. At the surface,
east/southeast flow will continue between a persistent weak low
pressure trough well to our west and strong high pressure to our
northeast. It appears that winds will remain easterly enough to
prevent blocking by the Big Island of the smaller islands, so
expect trade winds to become strong and gusty in many areas by
midweek. Downsloping effects may allow the winds to be strong
enough to require Wind Advisories for some areas.

As for rain chances, Monday looks like a transition day with trade
winds taking hold and shower intensity diminishing during the day.
Some heavier showers will remain possible over the western end of
the state, especially in the morning. Models show a drier airmass
moving in from the northeast on Tuesday, with PW values dropping
to around one inch. Thereafter, expect a strong trade wind
pattern, with passing showers focused over windward and mauka
areas. The strength of the trades will allow some showers to spill
over leeward.

&&

.AVIATION...
High pressure far NE of the area and a broad surface trough W of
Kauai, will keep locally strong E to SE winds over the islands
tonight. The trough of low pressure will shift westward on Monday,
allowing a more typical easterly trade wind regime to overspread
the island chain.

Widespread MVFR cigs/vsbys are expected to continue over windward
areas of Kauai Oahu Molokai Maui and the Big Island overnight,
with conditions improving in most areas around mid morning Monday.
Conditions will be a bit more unsettled across Oahu and Kauai at
least through the evening, with the potential for heavy rainfall
and thunderstorms, along with MVFR cigs/vsbys even in leeward
areas.

AIRMET Sierra remains in effect for mountain obscuration across
Kauai and Oahu, and for windward sections of Molokai, Maui, and
the Big Island. These conditions will likely continue through mid
morning Monday, although leeward sections of Kauai and Oahu may
improve later tonight.

AIRMET Tango remains in effect for low level turbulence due to
strong east to southeast winds, and this AIRMET will likely
continue through Monday. AIRMET Tango also remains in effect for
moderate upper level turbulence for the entire island chain and
will likely continue through Monday as well.

AIRMET Zulu remains in effect for moderate icing over Kauai and
Oahu. These conditions will likely improve later tonight. Light
icing is also mentioned for the remaining islands.

&&

.MARINE...
A very moist and unstable air mass will maintain a threat of
thunderstorms across the western half of the state through early
Monday morning. Mariners should be alert for reduced visibilities
in heavy downpours, locally gusty and shifting winds, increased
seas and frequent lightning in the vicinity of any thunderstorms
that develop over the ocean.

A Small Craft Advisory (SCA) remains posted through Tuesday
afternoon for most waters, including all windward areas, due to
strong east-southeast winds and elevated rough seas. The east-
southeast winds are forecast to strengthen Tuesday. As a result,
gale conditions are possible over some waters adjacent to the
islands of Maui County and the Big Island starting Tuesday. The
winds may be near gale force over these areas through mid-week.
Otherwise, expect SCA conditions to prevail over most waters
through Friday.

A long and relatively broad fetch of strong easterly winds along
the southern flank of the circulation around a large subtropical
high over the northeast Pacific will continue to produce a large
east swell this week. This east swell is generating elevated surf
along east facing shores. Therefore, a High Surf Advisory (HSA)
remains in effect for most east facing shores through Monday
afternoon. The strengthening winds upstream of the state will
cause the east swell to build. Therefore, surf may reach the High
Surf Warning criteria along east facing shores starting Monday
night or Tuesday. This elevated surf will likely continue into
next weekend. The long duration of this large surf combined with
strong onshore winds and large astronomical tides will likely
result in coastal inundation, especially during the highest
tides, along some vulnerable low lying sections of the east
facing shorelines later this week.

Small northwest swells are forecast to keep surf well below
normal along most north and west facing shores this week. The
east swell energy wrapping around to some select north and south
facing shores may produce localized bumps in surf heights along
some exposed northern and southern beaches across the island
chain.

.HFO WATCHES/WARNINGS/ADVISORIES...
Flash Flood Watch until 6 AM HST Monday for Niihau-Kauai.

High Surf Advisory until 6 PM HST Monday for east facing shores of
Kauai Oahu Molokai Maui and the Big Island.
