PNSHFO/ FOR MORE INFORMATION ON RAINFALL TOTALS.

WINDS INCREASED ACROSS THE STATE OVERNIGHT AS STRONG TRADE WINDS
BUILD IN AS THE FRONT DISSIPATES. THE PRESSURE DIFFERENCE BETWEEN
BUOY 51100 AND BUOY 51002 HAS INCREASED FROM 1.5 MB WEDNESDAY
MORNING TO 5.7 MB THIS MORNING...HENCE THE INCREASE IN WINDS OVER
THE STATE. THE PRESSURE GRADIENT ACROSS THE STATE IS BEING DRIVEN
BY A 1027 MB HIGH PRESSURE CENTERED JUST NORTH OF 30N ACROSS THE
CENTRAL PACIFIC. THE HIGH WILL REMAIN IN PLACE THROUGH THE WEEKEND
MAINTAINING FRESH TO LOCALLY STRONG TRADE WINDS.

FOR THE EXTENDED FORECAST...BOTH THE GFS AND ECMWF SHOW A MID
LATITUDE TROUGH MOVING INTO POSITION NORTHWEST OF THE STATE EARLY
NEXT WEEK. THIS SCENARIO WOULD BRING SOUTHEAST FLOW OVER THE
ISLANDS. HOW MUCH MOISTURE THE ISLANDS WILL GET DEPENDS HIGHLY ON
HOW CLOSE THIS TROUGH IS TO THE STATE. MODEL COMPARISONS BETWEEN
THE ECMWF AND THE GFS SHOW A LARGE DISCREPANCY BETWEEN THE PLACEMENT
OF THE TROUGH...SO THERE IS LITTLE CONFIDENCE IN EITHER SOLUTION.
THE LATEST POP FORECAST REMAINS CLOSE TO CLIMO WITH WINDS SHIFTING
OUT OF THE ESE.

.AVIATION...
THE REMNANT OF A FRONTAL CLOUD BAND  WILL CONTINUE TO AFFECT THE
ISLANDS FROM KAUAI TO THE BIG ISLAND OF HAWAII...PRODUCING
WIDESPREAD MOUNTAIN OBSCURATION. STRONG NNE WINDS WILL PRODUCE LOCAL
LOW-LEVEL MODERATE TURBULENCE.

.MARINE...
THE WAIMEA BAY BUOY INDICATES A SLIGHT INCREASE IN THE SWELL
OVERNIGHT...WITH CONSISTENT SWELL HEIGHTS OF 12 FEET AND PERIODS OF
13 SECONDS. A HIGH SURF WARNING REMAINS IN EFFECT FOR THE NORTH AND

AT KAHULUI HARBOR CONTINUES. A MARINE WEATHER STATEMENT HAS BEEN
ISSUED TO HIGHLIGHT THE DANGER OF HARBOR SURGES.

A SMALL CRAFT ADVISORY...SCA...REMAINS IN EFFECT FOR ALL OF THE
HAWAIIAN COASTAL WATERS DUE TO HAZARDOUS SEAS CREATED BY THE LARGE
SWELL...EXCEPT WATERS THE SOUTH OF THE BIG ISLAND AND MAALAEA BAY.
HOWEVER...THESE COASTAL WATERS WILL BE ADDED TO THE SCA STARTING 6
AM HST THIS MORNING DUE TO ELEVATED WIND SPEEDS. THE SCA GOES UNTIL
6 AM HST FRIDAY...ALTHOUGH IT WILL LIKELY NEED TO BE EXTENDED FOR
THE TYPICALLY WINDIER CHANNELS AND COASTAL WATERS DUE TO PERSISTENT
BREEZY TRADES THAT ARE EXPECTED TO LAST THROUGH THE WEEKEND.
