Area Forecast Discussion
National Weather Service Honolulu HI
941 AM HST Sun Feb 26 2023

.SYNOPSIS...
Strong high pressure building to the north of the islands will
drive strengthening trade winds into Monday, with windy
conditions then expected to linger through Thursday. Expect
scattered to numerous showers over windward areas this week, with
a few showers reaching leeward communities. Winds may decrease by
the end of the week as the high moves away and a front
approaches.

&&

.DISCUSSION...
A very strong high far north of the main Hawaiian Islands is
driving breezy to strong trade winds across local waters this
morning. Overnight soundings show a dry and stable airmass, while
satellite loop shows patchy broken low clouds moving across
windward areas within trade flow. Radar shows scattered showers
within this cloud cover. Broken showery low clouds extend east
and southeast of the Big Island, with scattered low clouds noted
immediately upstream of the other islands. Models show the bulk of
this moisture will pass southeast of the Big Island this morning,
with windward shower coverage expected to diminish through this
afternoon. Expect a breezy to windy day with just a few windward
showers. Models show a subtle increase in windward showers this
evening into Monday.

The high to our north will move slowly south southeastward over
the next several days, causing trade winds to strengthen.
Expect windy conditions from tonight into Thursday. Wind
Advisories may be needed for parts of the state. An upper low is
forecast to deepen to the east of the islands at the same time,
likely leading to destabilization of incoming low clouds and the
onset of a wet and windy trade wind pattern. Expect frequent
windward showers, with showers occasionally spreading leeward.
Winds may decrease by the end of the week as a front approaches
from the northwest and the high moves away from the islands.

&&

.AVIATION...
A strong high pressure system far north of Hawaii will drive
strong trade winds across the islands. AIRMET Tango is in effect
for tempo moderate/isolated severe low-level turbulence leeward
of the mountains and islands.

Trades will deliver scattered moderate showers that will focus
over windward slopes and provide brief MVFR ceilings and mountain
obscurations. No AIRMET Sierra at this time, but guidance suggests
incoming trade wind showers will increase tonight, likely
bringing more extensive clouds over the islands. For today, VFR
conditions prevail.

&&

.MARINE...
A strong high pressure system building in far north of the
Hawaiian Islands will increase trade winds once again into the
strong to gale range this week. A Gale Watch is in place for the
windier eastern waters and channels near Maui and the Big Island
through Wednesday. A Small Craft Advisory remains in effect for
all other coastal waters and channels through Wednesday.

As the trades strengthen during the next few days, the trade wind
swell will be on the rise. A High Surf Advisory (HSA) has been in effect
for east facing shores for many days now and will continue through
around Thursday.

The current small northwest swell (310-320 degrees) will decline
through tonight. Surf heights along north and west facing shores
will remain below normal through the week as high pressure
dominates the North Pacific. A weak low currently in the far
Northwest Pacific near the Kuril Islands will send a small long-
period northwest swell (310-320 degrees) and should arrive around
Thursday night into Friday. Minimal surf is expected from the
southern hemisphere with mainly windswell wrapping into select
south facing shores this week.

&&
