AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HONOLULU HI
400 AM HST TUE MAR 14 2006

.SYNOPSIS...
A WET PATTERN WITH A THREAT OF HEAVY RAINFALL OVER KAUAI AND OAHU
TODAY...WITH THE THREAT SPREADING EASTWARD TO THE OTHER ISLANDS
LATER IN THE WEEK. A GRADUAL DRYING TREND IS EXPECTED FRIDAY AND
SATURDAY...BUT MORE RAIN COULD COME AS EARLY SUNDAY AND MONDAY.

&&

.DISCUSSION...
MODERATE TO HEAVY RAIN CONTINUES TO FALL ON KAUAI/S SATURATED SOILS
THIS MORNING...CREATING FLOODING PROBLEMS...WHILE MODERATE TO HEAVY
SHOWERS HAVE BEEN UP AND DOWN ALONG THE WINDWARD SLOPES OF THE
KOOLAUS ON OAHU. WHILE THE RAIN HAS NOT BEEN AS WIDESPREAD FOR
MAUI COUNTY AND THE BIG ISLAND...SOME OF THE WETTER WINDWARD GAGES
HAVE RECORDED BETWEEN 2 AND 3 INCHES OF RAIN IN THE LAST 24 HOURS.
RADAR DETECTS A DEVELOPING AREA OF HEAVY RAIN MOVING NORTH-NORTHEAST
OVER WATERS SOUTH AND WEST OF NIIHAU...AND WILL AFFECT KAUAI WITH
ANOTHER SHOT OF TORRENTIAL RAIN SHORTLY. THUS FAR NO THUNDERSTORMS
HAVE BEEN REPORTED WITH THIS EVENT...WITH RADAR ECHO TOPS MAXING OUT
AROUND 30 THOUSAND FEET. 24 HOUR PRESSURE FALLS OF 2 TO 3 MILLIBARS
CONTINUE TO PORTEND THE EVENTUAL DEVELOPMENT OF A WEAK SURFACE LOW
PRESSURE/TROUGH NEAR THE ISLANDS...AS GLOBAL MODELS SUGGEST. WATER
VAPOR IMAGERY SHOWS A COMPLEX UPPER TROUGH WEST THROUGH NORTH OF
KAUAI...WITH A DIGGING SHORTWAVE NEAR 31N 167W.

AS PER THE HYDROMETEOROLOGICAL PREDICTION CENTER/S RECENT
DISCUSSION.../A SUBSTANTIAL HAWAIIAN ISLAND EXCESSIVE RAINFALL
THREAT WILL SPREAD SLOWLY ACROSS THE STATE OVER THE NEXT FEW DAYS AS
DEEP LAYERED TROPICAL MOISTURE CONVERGES OVER THE STATE IN ADVANCE
OF THE SLOW APPROACH OF AN AMPLIFIED SYSTEM./ THE AMPLIFIED SYSTEM
TO WHICH THE DISCUSSION IS REFERRING IS THE UPPER TROUGH TO OUR
NORTHWEST...AND AN ASSOCIATED MID LEVEL LOW THAT IS APPROACHING THE
CHAIN FROM THE NORTHWEST. THE MID LEVEL CUT OFF LOW IS FORECAST TO
DIG TOWARDS THE ISLANDS ALONG ROUGHLY 165W LONGITUDE TODAY THROUGH
THURSDAY...BEFORE BEING EJECTED TO THE NORTHEAST ON FRIDAY. THE
ENERGY MOVING IN FROM THE NORTHWEST THAT ACTS TO EJECT THIS FIRST
LOW WILL HELP TO SHARPEN YET ANOTHER UPPER TROUGH TO OUR NORTHWEST
LATE THIS WEEKEND AND EARLY NEXT WEEK...PERHAPS BRINGING ANOTHER
ROUND OF HEAVY RAIN.

IN RESPONSE TO THE DIGGING MID LEVEL LOW...MODELS DEVELOP A TROUGH
WEST OF THE ISLANDS AND MOVE IT EASTWARD OVER THE ISLAND CHAIN...
WHICH WILL ACT TO BRING A DEEP SOUTHERLY FLOW OVER ALL ISLANDS. GFS
DEVELOPS AN ENTIRE SERIES OF LOWS ALONG THIS TROUGH NEAR THE ISLANDS
AROUND MIDWEEK...AND RECENT NOGAPS RUNS CONCUR...SO IT APPEARS WEAK
CYCLOGENESIS AT OUR LATITUDE IS IMMINENT. IT WILL BE DIFFICULT TO
PINPOINT WHEN AND WHERE HEAVY RAINFALL WILL OCCUR THE NEXT COUPLE OF
DAYS...BUT IT IS NOT DIFFICULT TO SAY THAT HEAVY RAINFALL WILL
OCCUR...WHICH WILL LIKELY LEAD TO FLASH FLOODING. NO CHANGES AT THIS
POINT TO THE FLOOD WATCH.
