.SYNOPSIS...
THE WET WEATHER WILL PERSIST THROUGH THE FINAL WEEK OF MARCH AS

PHILOSOPHY BEHIND THE FORECAST REMAINS UNCHANGED. ONE SLUG OF
MOISTURE MOVED THROUGH MAUI COUNTY IN THE PAST FEW HOURS WITHOUT
MUCH FANFARE...WHILE KAUAI AND OAHU WERE RATHER QUIET...FOR A
CHANGE. BUT THIS IS SHORT LIVED AS A SHORT WAVE OR DISTURBANCE ALOFT

ISLANDS. AT LEAST THE MORNING HOURS WILL BE SOGGY. THE NEXT BATCH OF
MOISTURE IS SLATED FOR WEDNESDAY INTO THURSDAY AS YET ANOTHER STRONG
TROUGH SWOOPS DOWN FROM THE NORTHWEST AND SLOWLY PUSHES THROUGH THE
MAIN HAWAIIAN ISLANDS. ALL ISLANDS WILL GET THEIR SHARE OF WEATHER.
WINDWISE...FOR THE EXCEPT FOR THE BIG ISLAND...THE EASTERLY WINDS
ARE QUICKLY VEERING TO THE SOUTH THIS MORNING. BY TOMORROW OR
TUESDAY AFTERNOON...ALL ISLANDS SHOULD BE SOUTHERLY...AHEAD OF A
WEAKENING COLD FRONT. THIS FRONT IS SLATED TO BECOME AN INVERTED
TROUGH BY THURSDAY OVER THE CENTRAL ISLANDS...FOLLOW BY DISSIPATION
FRIDAY. ITS DEMISE MEANS THE RETURN OF THE TRADES OVER THE WEEKEND.
