Area Forecast Discussion
National Weather Service Honolulu HI
930 AM HST TUE AUG 30 2016

.SYNOPSIS...
Moisture embedded in the trades will cause passing showers mainly for
windward and mauka areas today. Beyond that the weather pattern
will be highly dependent on the track and intensity of Hurricane`s
Madeline and Lester.

&&

.DISCUSSION...
High pressure centered far north of the area places the islands in
a moderate trade wind environment. An area of moisture embedded in
the trades will provide for passing showers mainly over windward
and mauka areas today.

The weather pattern for the remainder of the week and on through
the weekend will be highly dependent on the tracks and intensities of
both Hurricane`s Madeline and Lester.

The latest forecast for Hurricane Madeline is for it to pass by
near or just south of The Big Island Wednesday night and Thursday,
and pass by south of the remainder of the state Thursday and
Friday. For more details on Madeline, please refer to products
issued by The Central Pacific Hurricane Center.

Winds and heavy rain associated with Madeline are expected to
impact The Big Island and possibly Maui County with less wind and
rain effects for the rest of the state. For more details on these
conditions, please refer to the Hurricane Local Statement.

After the passage of Madeline, there will be a brief period of
typical trade wind weather as high pressure remains far north of
the area.

As we head into the weekend, Hurricane Lester is forecast to pass
by just north of the state. For more details on Lester, please
refer to products issued by The National Hurricane Center in
Miami, Florida.

Depending on the track and intensity of Lester, heavy rain and
winds could impact portions of the state over the holiday weekend.

&&

.AVIATION...
VFR will prevail over most of the island chain today, with brief
MVFR conditions likely in windward and mauka areas as moisture on
the extreme western periphery of Hurricane Madeline makes its way
through the state. Breezy trade winds will persist, especially
with the approach of Madeline.

No AIRMETs are currently in effect.

&&

.MARINE...
Winds and seas will be highly dependent on the track and intensity
of Madeline and will be highly variable from one location to
another.

High surf along east facing shores can be expected in association
with Madeline. The largest waves will be along east facing shores
of The Big Island with heights becoming lower as you go up the
island chain.

Winds, seas and surf will decrease after the passage of Madeline
but will once again increase this weekend in association with
Lester.
