AREA FORECAST DISCUSSION...CORRECTED
NATIONAL WEATHER SERVICE HONOLULU HI
915 AM HST SUN AUG 23 2015

.SYNOPSIS...
DEEP TROPICAL MOISTURE WILL REMAIN OVER THE ISLANDS FOR THE NEXT
SEVERAL DAYS...THEREBY FUELING LOCALLY HEAVY SHOWERS AND
THUNDERSTORMS...AND A FLASH FLOOD WATCH REMAINS IN EFFECT FOR ALL
ISLANDS. LIGHT WINDS WILL FAVOR A SOUTHEASTERLY DIRECTION FOR THE
NEXT SEVERAL DAYS...WITH LIGHT TO MODERATE TRADE WINDS EXPECTED TO
RETURN DURING THE SECOND PART OF THE WEEK. EVEN WHEN TRADE WINDS
RETURN...THE ATMOSPHERE WILL REMAIN QUITE MOIST. ALTHOUGH THE LATEST
FORECAST FROM THE CENTRAL PACIFIC HURRICANE CENTER KEEPS THE CENTER
OF KILO SEVERAL HUNDRED MILES WEST OF KAUAI LATER THIS WEEK...YOU
SHOULD CONTINUE TO MONITOR THE LATEST FORECASTS.

&&

.DISCUSSION...
ALTHOUGH TROPICAL CYCLONE KILO IS CENTERED WELL SW OF THE
ISLANDS...SOUTHERLY FLOW TO THE E OF THE SYSTEM HAS DRAGGED A VERY
MOIST AND UNSTABLE AIR MASS OVER THE ISLANDS AND SURROUNDING
WATERS. WITH WEAK TROUGHING ALOFT JUST N OF THE AREA...THE AIR MASS
IS UNSTABLE...SUPPORTING HEAVY SHOWERS AND THUNDERSTORMS. WITH
SURFACE DEW POINTS IN THE MID TO UPPER 70/S...SWEAT DOES NOT
EVAPORATE AS QUICKLY...THEREBY PREVENTING THE BODY FROM RELEASING
HEAT QUICKLY. IF PARTICIPATING IN STRENUOUS OUTDOOR ACTIVITIES...BE
SURE TO DRINK PLENTY OF NON-ALCOHOLIC FLUIDS. ALSO IF VENTURING
OUTDOORS...BE AWARE OF THE THREAT POSED BY LIGHTNING...AND REMEMBER
THAT LIGHTNING CAN STRIKE EVEN IF IT IS NOT RAINING AT YOUR
LOCATION. IF THUNDER ROARS...GO INDOORS.

THE SYNOPTIC SITUATION FEATURES THE LOW PRESSURE ASSOCIATED WITH
KILO SEVERAL HUNDRED MILES SW OF THE ISLANDS...AND A SURFACE HIGH
CENTERED FAR N OF THE AREA...NEAR THE ALEUTIAN ISLANDS. THE GRADIENT
BETWEEN THESE FEATURES IS SUPPORTING A LIGHT SE FLOW OVER THE
AREA...AND WITH A WEAK SURFACE LOW WELL N OF THE ISLANDS NEAR 32N
160W PERSISTING FOR THE NEXT COUPLE OF DAYS...LITTLE CHANGE IN THE
OVERALL WIND PATTERN IS EXPECTED FOR THE NEXT COUPLE OF DAYS. WEAK
TROUGHING ALOFT WILL PERSIST JUST N OF THE AREA...AND COMBINED WITH
THE DEEP MOISTURE...HEAVY SHOWERS AND THUNDERSTORMS WILL REMAIN
POSSIBLE THROUGH ABOUT MID-WEEK. ALTHOUGH THE OFFICIAL FORECAST FROM
THE CENTRAL PACIFIC HURRICANE CENTER BRINGS KILO CLOSER TO THE W END
OF THE CHAIN LATE IN THE WEEK...THIS IS THUS FAR NOT EXPECTED TO
LEAD TO INCREASED WINDS OVER THE AREA.

MOISTURE OVER THE AREA IS EXPECTED TO DIMINISH SOMEWHAT AROUND
THURSDAY AND FRIDAY...BUT A WEAK TROUGH ALOFT IS FORECAST TO EXTEND
OVER THE AREA FROM THE NE AS NEXT WEEKEND APPROACHES. THE HIGH TO
THE N WILL REMAIN QUITE DISTANT...AND WITH KILO FORECAST BY CPHC TO
BE W OF THE AREA...A LIGHT TRADE WIND FLOW IS EXPECTED FROM ABOUT
MID-WEEK INTO NEXT WEEKEND. THUS CLOUDS AND SHOWERS ARE EXPECTED TO
FAVOR WINDWARD AND MAUKA AREAS...BUT WINDS MAY BE LIGHT ENOUGH TO
ALLOW AFTERNOON SEA BREEZES TO DRIVE CLOUD AND SHOWER DEVELOPMENT
OVER LEEWARD SLOPES AND COASTS.

ALL INTERESTS IN THE STATE OF HAWAII SHOULD CLOSELY FOLLOW THE
PROGRESS OF KILO BY MONITORING THE LATEST BULLETINS AND PRODUCTS
ISSUED BY THE CENTRAL PACIFIC HURRICANE CENTER AND THE NATIONAL
WEATHER SERVICE OFFICE IN HONOLULU.

&&

.AVIATION...
OUR VERY MOIST AND UNSTABLE AIRMASS MAY PRODUCE HEAVY SHOWERS AND
THUNDERSTORMS ANYWHERE ACROSS THE AREA THROUGH TODAY. VFR IS
FORECAST TO DOMINATE AT THE TERMINALS...BUT MVFR AND IFR CONDITIONS
COULD OCCUR ELSEWHERE WITHIN DEEP CONVECTION THIS AFTERNOON. AIRMET
SIERRA IS IN EFFECT OVER WINDWARD AND SOUTHEAST FACING BIG ISLAND
SLOPES FOR OCCASIONAL MOUNTAIN OBSCURATION ABOVE 1000 FEET DUE TO
DEVELOPING SHOWERS AND THUNDERSTORMS.

&&

.MARINE...
A SMALL TO MODERATE W SWELL WILL CONTINUE OVER THE ISLANDS THROUGH
THE MIDDLE OF THE WEEK. A SLIGHTLY LARGER VERY LONG PERIOD WNW
SWELL...GENERATED BY DISTANT TYPHOON ATSANI...IS EXPECTED TO ARRIVE
AROUND WEDNESDAY...PEAKING THURSDAY INTO FRIDAY. THIS SWELL...WITH
OPEN OCEAN SWELL HEIGHTS EXPECTED TO BE AROUND 4-5 FEET...MAY BE
LARGE ENOUGH TO BRING ADVISORY LEVEL SURF TO THE W FACING SHORES OF
THE BIG ISLAND.

MARINERS MAY ENCOUNTER HEAVY SHOWERS OR THUNDERSTORMS AS A VERY
MOIST AND UNSTABLE AIR MASS REMAINS ACROSS THE AREA THROUGH THE NEXT
COUPLE OF DAYS. A MARINE WEATHER STATEMENT HAS BEEN ISSUED TO
HIGHLIGHT THE THREAT TO MARINERS.

WITH THE PRESENCE OF KILO NEARBY...SMALL CHANGES IN THE TRACK OR
INTENSITY OF THIS SYSTEM MAY LEAD TO BIG CHANGES IN THE FORECAST FOR
THE COASTAL WATERS AS WELL AS THE POTENTIAL FOR ROUGH SURF FOR THE
ISLANDS LATER THIS WEEK. MARINERS SHOULD MONITOR FORECASTS FOR THE
LATEST UPDATES BEFORE HEADING OUT...ESPECIALLY IF PLANNING TRIPS TO
THE OFFSHORE WATERS.

&&

.HFO WATCHES/WARNINGS/ADVISORIES...
