AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HONOLULU HI
330 AM HST TUE AUG 30 2011

.SYNOPSIS...
A SURFACE RIDGE OF HIGH PRESSURE FAR NORTH OF THE ISLANDS WILL
MAINTAIN MODERATE TRADE WIND SPEEDS THROUGH FRIDAY...WITH A DECREASE
IN WINDS IN STORE FOR THE WEEKEND. THE TRADE SHOWERS WILL BE A BIT
MORE ACTIVE THAN USUALLY DUE TO AN UPPER LEVEL LOW NORTH OF THE
ISLANDS. THE PASSING TRADE SHOWERS WILL BE A BIT MORE FREQUENT AND
SOME OF THESE SHOWERS WILL BE BRIEFLY HEAVY THROUGH TONIGHT. A DRIER
TRADE WIND PATTERN RETURNS FOR THE SECOND HALF OF THE WEEK.

&&

.DISCUSSION...
THERE ARE A COUPLE OF ADJUSTMENTS TO THE FORECAST PACKAGE OVERNIGHT.
THE FIRST OF TWO IS THE DROPPING OF THE LOCALLY HEAVY SHOWERS FOR
THE BIG ISLAND...WHERE THE MORNING SOUNDING FROM HILO SHOWS A STABLE
TYPICAL TRADE WIND PROFILE. THE SECOND ADJUSTMENT HAD TO DO WITH THE
POPS WHERE SOME AREAS WITH ZERO POPS NOW HAVE AT LEAST ISOLATED
SHOWERS THROUGH TONIGHT.

THE CLOUDS AND SHOWERS DID NOT FILL IN AS MUCH ACROSS THE WINDWARD
WATERS COMPARED TO THE PAST FEW NIGHTS...AND THIS IS DESPITE THE
UPPER LOW. STILL...THE RAINFALL READINGS FOR THE PAST 6 HOURS ENDING
AT 2 AM HST...POINTED TO A SHOWERY EVENING FOR A COUPLE OF
ISLANDS...PARTICULARLY KAUAI. A COUPLE OF RAIN GAGES ON THE WINDWARD
SIDE COLLECTED MORE THAN .2 TENTHS OF AN INCH. A GOOD CHUNK OF OAHU
HAD SHOWERS WITH MAJORITY OF THE TOTALS BELOW 15 HUNDREDTHS OF AN
INCH.

SHOULD NOTE THE LOW LEVEL WINDS HAS VEERED TO THE EAST FROM NORTHEAST
OVERNIGHT. SATELLITE IMAGERY SHOWS AN AREA OF BROKEN LOW CLOUDS
SPREADING WESTWARD ONTO THE HAMAKUA COAST OF THE BIG ISLAND AND
WINDWARD MAUI. LOOK FOR THIS AREA OF MOISTURE TO CONTINUE WESTWARD
ONTO MOLOKAI AND OAHU THE REST OF THIS MORNING.

OTHERWISE...WE WILL STAY WITH THE GAME PLAN...OF SHOWERS LIKELY OVER
THE WINDWARD AND MOUNTAIN AREAS OF THE SMALLER ISLANDS THROUGH
TONIGHT. THE LEEWARD COMMUNITIES WILL HAVE SCATTERED SHOWERS THIS
MORNING...BECOMING ISOLATED BY AFTERNOON. SHOWERS INCREASES ONCE
THE SUN SETS TONIGHT.

A DRIER TRADE WIND PATTERN SHOULD BE SETTLING BACK IN WEDNESDAY AS
THE UPPER LOW MOVES OUT OF RANGE.

FYI...WEATHER RADAR DATA FROM THE MOLOKAI WSR-88D /WEATHER
SURVEILLANCE RADAR 88-DOPPLER/ WILL NOT BE AVAILABLE THROUGH
SEPTEMBER 23 2011. DURING THIS PERIOD...THE SUPPORTING STRUCTURE TO
THE RADAR WILL BE REPLACED DUE TO EXTENSIVE CORROSION.

&&

.AVIATION...
WE WILL BE MONITORING CLOSELY THE MVFR CONDITIONS ASSOCIATED WITH
THE SHOWERS. THE FREQUENCY OF THE SHOWERS HUNG UP OVER THE MOUNTAINS
MAY WARRANT A MOUNTAIN OBSCURATION. MOST OF THE CLOUD TOPS ARE AT 10
TO 12 THOUSAND FEET WEST OF MOLOKAI THIS MORNING. T
&&

.MARINE...

SOME PARTS OF THE SOUTH AND WEST FACING SHORES LINES MAY EXPERIENCE
LOCAL COASTAL FLOODING...SUCH AS THE CASE OF WATER REACHING THE
ROADS IN THE MAKAHA AREA OF OAHU MONDAY EVENING. THIS IS DUE TO THE
ABOVE NORMAL SOUTH SWELL COMBINED WITH THE ASTRONOMICAL TIDE OF
AROUND 2 FEET. THERE WILL BE TWO HIGH TIDES TODAY OF AROUND 2
FEET...THE FIRST SHORTLY BETWEEN 4 AND 6 AM...AND THE OTHER AT 430
AND 6 PM. WE HAVE RAISED THE SURF FOR THE SOUTH FACING SHORES FROM 6
TO 10 FEET TO 8 TO 12 FEET FOR TODAY AS THE SECOND REINFORCING SWELL
ARRIVES. THERE WILL BE OCCASIONAL HIGHER SET WITH THIS SECOND SET OF
SWELLS.

NO SMALL CRAFT ADVISORIES...SCA...ARE POSTED OVER ANY HAWAIIAN
WATERS. HOWEVER...TRADE WIND SPEEDS ACROSS THE TYPICALLY WINDY
WATERS AND CHANNELS AROUND MAUI AND THE BIG ISLAND WERE NEAR THE SCA
CRITERIA YESTERDAY. SO WE WILL BE KEEPING A CLOSE WATCH ON THIS.
THE PRESSURE GRADIENT NOW IS SIMILAR TO THAT OF 24 HOURS AGO. SO WE
EXPECT THE TRADES TO COME CLOSE TO SCA LATER THIS MORNING.

A TRADES WILL BE TRENDING LIGHTER OVER THE WEEKEND.

.HFO WATCHES/WARNINGS/ADVISORIES...
HIGH SURF ADVISORY FOR SOUTH FACING SHORES OF ALL HAWAIIAN ISLANDS
THROUGH 6 AM HST THURSDAY.
