Small Craft Advisory 61, NWS Honolulu, HI

Area Forecast Discussion
National Weather Service Honolulu HI
338 PM HST Mon Nov 21 2016

.SYNOPSIS...
A rather windy and wet trade wind weather pattern can be expected
over the next several days. Showers will tend to favor windward
and mauka areas but the winds will be sufficiently strong enough
to blow some showers over the leeward areas at times. Besides the
showery low clouds there will also be an abundant amount of high
clouds passing over the area causing sky's to be on the cloudy
side. A bit drier weather is expected toward the weekend but it
will still be on the breezy side.

&&

.DISCUSSION...
Strong high pressure building in north of the area will be responsible
for a rather breezy to locally windy trade wind weather pattern over
the next several days. This is the result of a tight pressure gradient
south of the high. Winds may become strong enough at times to require
a wind advisory over some locations especially over portions of
Maui County and The Big Island.

Moisture embedded in the trades will provide for passing showers
over windward and mauka areas with the trade winds sufficiently
strong enough to blow some showers over to leeward areas at times.
Models also indicate that there will be periods of high clouds
passing over the area from time to time causing sky conditions to
be a bit more cloudy than usual. Models indicate that a drier
airmass will move in from the east later in the week and on into
the weekend with shower activity expected to decrease.

&&

.AVIATION...
An area of increased low-level moisture lies near and just upstream
of all islands, and will continue to stream over the islands from
the E through at least tonight. This moisture will impact windward
areas with widespread MVFR VIS/CIG in -SHRA, with periods of IFR
VIS/CIG in +SHRA. The trade winds, which are expected to significantly
strengthen over the next 12-24 hours, will act to spread this moisture
to leeward areas of most islands, producing periods of MVFR conditions
there as well.

AIRMET SIERRA is likely to remain posted thorugh the night for
mountain obscuration over most islands, and AIRMET TANGO has been
issued for low-level turbulence to the S and W of island terrain.

&&

.MARINE...
A Gale Warning has been posted for the typically windy waters
around Maui County and The Big island with a Small Craft Advisory
posted for all other Hawaiian coastal waters. These conditions
will likely linger through the remainder of the week.

High surf can be expected along east facing shores this week due
to the strong trade winds with conditions being rather rough and
choppy at most locations.

Surf along most north and west facing shores will be lower than
average for this time of year as the strong high to our north
causes the storm track to be further north than normal. There will
be a series of small north and northwest swells this week but surf
heights will remain well below advisory levels.
