SATELLITE ANALYSIS AND TRENDS...HVY RAIN/FF THREAT CONTINUES TO EVOLVE
AND SPREAD WESTWARD THRU OAHU AND EVEN KAUAI.  SATELLITE WINDS INDICATING
UPPER LEVEL TROUGH TO THE WEST MAY HAVE CLOSED OFF TO A LOW NEAR 22N/167W.
BUT DEFINITELY A DISTINCT TROUGH EXTENDING FROM HERE SSE TO NEAR 10N/165W.
JET NOT AS STRONG OVER THE BIG ISLAND AND THIS MAY BE BECAUSE HIGH LEVEL
IMPULSE APPROACHING SOUTHERN ISLANDS FROM THE SW WAS BULGING CIRRUS
CLOUDS AND WEAK SHORT WAVE RIDGE RIGHT OVER THOSE SOUTHERN ISLANDS.
FURTHER APPROACH OF SHORT WAVE AND STILL WEAK JET WITH 60-80KT WINDS
PROVIDING INSTABILITY, WHILE INCREASING MOISTURE SPREADING IN FROM THE
EAST AND SE PROVIDE THE DEEPER MOISTURE FOR HEAVY RAIN AND LOCALIZED FF.
SURFACE RIDGE OF HIGH PRESSURE AS PER QUIKSCAT AND SSMI WIND SPEEDS WAS
FROM 35N/155W TO 30N/137W AND THIS PROVIDING  AN INCREASE IN EASTERLY
WINDS ESPECIALLY ALONG THE NORTHERN COASTAL AREAS OF THE ISLANDS...WHICH
IS HELPING OROGRAPHICAL ENHANCEMENT FOR LATEST HVY SHOWERS TO AFFECT
MAUI...OAHU AND THE BIG ISLAND.  PERSISTENCE OF THIS PATTERN WITH
SATELLITE FEATURES ALL PLAYING A MAJOR ROLE WILL CONTINUE FOR A WHILE.
SO AREAS THAT HAVE ALREADY RECEIVED HVY RAIN WILL BE MOST VULNERABLE
FOR FLOODING.  WILL CONTINUE TO MONITOR...
