Area Forecast Discussion
National Weather Service Honolulu HI
328 PM HST Sat Feb 7 2026

.SYNOPSIS...
A cold front is slowing as it moves over the Alenuihaha Channel
towards the Big Island this afternoon. This frontal boundary
combined with increasing moisture and a disturbance aloft, will
bring the potential for heavy rainfall, flash flooding, and a few
rumbles of thunder through Monday. Breezy north to northeasterly
winds will continue to fill in behind the front, with the trades
then becoming very windy Sunday into Monday as strong high
pressure builds north of the state. Conditions will gradually
improve by mid to late next week, though breezy and showery trade
wind weather is expected to persist.

&&

.DISCUSSION...
Satellite and radar imagery this afternoon show mostly cloudy and
unsettled conditions across the state. A cold front moved across
Kauai and Oahu overnight into the early morning hours, then
through Maui County earlier today, bringing gusty north to
northeasterly winds in its wake along with periods of moderate to
heavy rainfall. As of around 2:30 PM, the front appears to be
slowly pushing across the Alenuihaha Channel toward the Big
Island.

Over the past 24 hours, north- and east-facing areas of Kauai,
Oahu, and Molokai have generally received 2 to 4 inches of
rainfall, much of which fell as the front passed through. Rainfall
rates have mostly remained manageable, limiting flooding impacts
overall. One exception occurred earlier today over Molokai, where
higher rates prompted a Flood Advisory. Since then, rainfall
rates have eased somewhat, with showers lingering near the frontal
boundary and broader stratiform showers streaming northeastward
across the western end of the state this afternoon. More recently,
heavier showers have developed over the North Kohala district of
the Big Island, prompting the issuance of a Flood Advisory there
as well.

This front will continue to slow and eventually stall and
dissipate in the vicinity of Maui County and the Big Island
heading into this evening. This feature will continue to be the
main focus for heavy showers through the evening, making the
flooding threat locations highly dependent on where this axis of
deep moisture and convergence sets up. Then as the front
dissipates, the moisture and forcing will become more diffuse
across the state, making it harder to pinpoint where and when the
heaviest rainfall will occur. High resolution model guidance
continues to show windward areas anywhere between Oahu and the Big
Island being the main focus for the highest rainfall through
Monday, making windward portions of Maui County the most likely to
see flooding during this period. However, the flooding threat
remains statewide and thus the Flood Watch remains in effect for
all islands. With the instability from the upper level disturbance
moving overhead, a few isolated thunderstorms may develop within
this shower activity, but chances remain low.

In addition to the flooding threat, damaging winds will become a
concern late Sunday into Monday as high pressure builds in from
the north and a surface trough develops and deepens into a low
west of the state. The resulting tightening pressure gradient
between these surface features will strengthen the trade winds
late Sunday into Monday, with the potential for High Wind Warning
level gusts (60+ mph) across mainly leeward downsloping areas or
in showers. The main impacts will likely be power outages, downed
trees (especially with saturated soils), and difficulty traveling
in high-profile vehicles. A High Wind Warning is now in effect for
most locations across the state Sunday through Monday.

Finally, winter weather impacts are possible for the Big Island
summits this weekend. As deep moisture overspreads the island, an
upper level disturbance nudges in from the northwest, and
temperatures aloft drop below freezing, conditions will become
favorable for heavy snowfall at the summits. As a result, a Winter
Storm Warning has been issued for the summits of Mauna Kea and
Mauna Loa from Sunday morning through Monday afternoon.

Conditions will gradually improve for the middle and latter
portion of next week, although a somewhat showery and breezy trade
wind pattern will likely persist.

&&

.AVIATION...
A stalled front over the central part of the state will be
enhanced by an upper trough to the west. AIRMET Sierra is posted
for tempo mountain obscurations above 2000 feet for all smaller
islands and likely continuing tonight into Sunday. MVFR with
localized IFR conditions will occur throughout the day. Clouds
will likely fill in over the Big Island later today making AIRMET
Sierra possible here as well.

AIRMET Tango posted for tempo moderate turbulence across all
smaller islands and adjacent waters due to the weather system over
the state. Moderate turbulence may occur across all portions of
these islands up to FL320.

Light icing is expected in cloud layer 120-FL230 from Kauai to
Maui.

&&

.MARINE...
Winds will increase significantly over the next 24 hours. A front
currently located near Maui will drift southward and dissipate
overnight. As confirmed by ASCAT passes last evening and this
morning, robust high pressure building north of the front is
driving fresh to strong northeast trade winds along and north of
the feature, while weaker easterly flow persists around the Big
Island. A Small Craft Advisory (SCA) remains in effect for all
waters from Kauai to Maui due to a combination of these winds and
large seas in excess of 10 feet, mainly in west-northwest swell.
The swell will lower tonight, but the stronger trade winds and the
coverage of the SCA will spread to all Hawaiian waters as the
front dissipates. As the high builds and low pressure develops
several hundred miles southwest of the islands on Sunday, trade
winds will strengthen to near gale to gale force over most waters
Sunday afternoon through Monday, and the Gale Watch has been
upgraded to a Gale Warning for all Hawaiian waters for this time.
In addition, expect heavy showers and isolated thunderstorms
through Monday. Winds are expected to ease some on Tuesday, but
trade will remain in the strong range with some near gales over
the windier waters through at least Wednesday.

A large west-northwest swell (295-310 degrees) peaked last night
and will gradually lower tonight and Sunday. Buoy observations
support downgrading the High Surf Warning (HSW) to a High Surf
Advisory (HSA) for exposed north and west facing shores from
Kauai to Maui, while the HSA for west facing shores of the Big
Island will be extended through tonight. Surf on all islands will
decline below HSA thresholds by Sunday morning. Small to moderate
north-northwest to northwest swells will prevail through the
remainder of the week.

Large and very rough seas will develop on Sunday as trade winds
strengthen. East shore surf should rise above the HSA threshold
Sunday night, with the potential for surf to reach the HSW level
Monday and Tuesday on Kauai and Oahu. Large east shore surf will
slowly decline Tuesday into Wednesday but will still remain
somewhat elevated through the remainder of the week. Surf along
south facing shores will remain small with some small background
south-southwest energy expected throughout the first half of next
week. Select southern exposures exposed to the wind swell will
likely see some larger waves as well.
