AREA FORECAST DISCUSSION...CORRECTION
NATIONAL WEATHER SERVICE HONOLULU HI
400 PM HST WED MAR 8 2006

INCLUDE SMALL CRAFT ADVISORY TO DISCUSSION

.SYNOPSIS...
SHOWER ACTIVITY WILL BE INCREASING INTO THURSDAY STATEWIDE AS LOW
PRESSURE CONTINUES TO DEEPEN WEST OF THE MAIN HAWAIIAN ISLANDS. IT
LOOKS LIKE THURSDAY WILL BE A WET ONE ESPECIALLY THE ISLANDS OF
KAUAI...PARTS OF OAHU...AND EASTERN BIG ISLAND. THE WEATHER IS
EXPECTED TO START IMPROVING FRIDAY AS HIGH PRESSURE BUILDS OVER THE
AREA.

&&

.DISCUSSION...
NO CHANGE TO THE PHILOSOPHY TO THE FORECAST. STILL LOOKING AT
THURSDAY TO BE AN ACTIVE WEATHER DAY ESPECIALLY FOR THE ISLAND OF
KAUAI AND EASTERN BIG ISLAND. OAHU WILL GET ITS SHARE OF SHOWERS AS
WELL BUT HEAVY SHOWERS ARE NOT EXPECTED TO BE WIDESPREAD. WE WILL
SEE AND WE WILL MONITOR THE SITUATION CLOSELY SINCE THE WINDWARD
SIDE REMAINS SENSITIVE TO HEAVY RAINFALL.

THE POOL OF MOISTURE CONTINUES TO AFFECT THE EASTERN SIDE OF THE
BIG ISLAND FROM LAUPAHOEHOE TO PUNA DISTRICT TO SOUTH POINT.
ABUNDANT MOISTURE REMAINS JUST OFFSHORE OF THE BIG ISLAND AND WILL
BE SPREADING TO THE REMAINING ISLANDS TONIGHT AND THURSDAY. HAVE
DISHED OUT A FLOOD ADVISORY FOR THIS PART OF THE BIG ISLAND...UNTIL
430 PM BUT IS LIKELY TO BE RENEWED. INSTABILITY IS INCREASING
STATEWIDE AS WELL. DOPPLER RADAR HAS SHOWN AN INCREASE IN SHOWER
ACTIVITY SOUTH OF KAUAI...NIIHAU AND LATELY SOUTH OF LANAI. THESE
SHOWERS WILL BE MOVING IN WITH THE SOUTHEAST WIND FLOW THAT IS
EXPECTED TO LAST THROUGH THURSDAY NIGHT. AN IMPROVING TREND IS
SLATED FOR FRIDAY AS TRADES TRIES TO TAKE HOLD. WE SHOULD BE BACK IN
A TRADE WIND REGIME SATURDAY WITH THE NORMAL WINDWARD AND MAUKA
SHOWERS.

SETTING THE GRID WAS A CHALLENGING TASK. RESULTS WERE NOT ALL THAT
SATISFACTORY. SO I APOLOGIZE FOR THE DISCREPANCIES BETWEEN THIS
DISCUSSION AND THE GRIDS.

ALSO...THE SOUTHEAST WINDS ARE QUITE BRISK OVER THE WINDWARD WATERS
OF OAHU...MOLOKAI AND MAUI AND SOUTHEAST BIG ISLAND...RESULTING IN
A SMALL CRAFT ADVISORY.
