.SYNOPSIS...
Breezy trades will focus clouds and showers over windward and
mauka areas through the week, especially during the overnight and
early morning hours.

&&

.DISCUSSION...
Typical June weather will persist through the week, with locally
breezy trade winds focusing showers over windward and mauka areas.
Broad surface high pressure far north of the state will
maintain trades near current strength through at least Wednesday,
followed by a slight decrease in winds on Thursday as the high
shifts to the northeast. A mid-level ridge overhead will maintain
stable conditions, and little organized moisture is forecast to be
moving along the trade wind flow. As a result, expect showers to
be focused along windward areas, especially at night, with
rainfall accumulations of less than a half of an inch per day at
most sites. Leeward areas will continue to be rather dry, except
for scattered afternoon showers along the Kona slopes of the Big
Island. Thin high clouds will pass over the islands into Monday,
then dissipate as an upper-level low west of the state drifts
away.

&&

.AVIATION...
Stable, breezy trades deliver clouds and showers mainly to
windward and mauka zones through the period. VFR prevails, but
MVFR will be possible within any showers.

AIRMET Tango remains in effect for low-level lee turb.

&&

.MARINE...
High pressure north of Hawaii will drive trade winds through the
week, with a slight weakening trend as the high moves away
eastward. A Small Craft Advisory (SCA) for the windier waters and
channels near Maui and the Big Island goes through Monday night,
likely extending beyond this point.

A series of small, long-period, south swells will help boost surf
heights along south facing shores though the week. The current
south swell will decline over the next couple days followed by
another south swell from Wednesday into Thursday.

Rough and choppy surf along east facing shores will continue this
week. Surf will remain nearly flat along north facing shores
throughout the forecast period.

&&

.HFO WATCHES/WARNINGS/ADVISORIES...
Small Craft Advisory until 6 AM HST Tuesday for Maalaea Bay-
Pailolo Channel-Alenuihaha Channel-Big Island Leeward Waters-Big
Island Southeast Waters.
