AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HONOLULU HI
830 PM HST FRI FEB 1 2008

.SYNOPSIS...
MODERATE TO FRESH TRADE WINDS WILL CONTINUE ACROSS THE STATE THIS
WEEKEND DUE TO A STRONG HIGH FAR NORTH OF THE ISLANDS. THE WET TRADE
WIND WEATHER IS EXPECTED TO PERSIST FROM TONIGHT THROUGH SUNDAY.

&&

DISCUSSION...
HEAVY RAINFALL CONTINUES OVER PARTS OF THE HILO AND PUNA DISTRICTS
ON THE WINDWARD BIG ISLAND. RADAR RAINFALL ESTIMATES...RAIN GAGES
AND SPOTTER REPORTS OF HEAVY RAINFALL...AND EVEN THUNDER...ALL
CONFIRMED THIS ABOVE NORMAL RAINFALL. SOME OF THE HEAVIER SHOWERS
APPEAR TO HAVE BEEN ANCHORED ALONG THE UPSLOPE REGION JUST INLAND
FROM HILO. THEY ARE BEING FED BY AMPLE LOW-LEVEL MOISTURE FLOWING IN
FROM THE EAST IN THE TRADES. A FLOOD ADVISORY WAS ISSUED ABOUT TWO
HOURS AGO FOR PORTIONS OF THIS AREA. THIS ADVISORY MAY NEED TO BE
EXTENDED IF THE HEAVY RAINFALL AND THE RESULTING RUNOFF CONTINUES.
IN FACT...RADAR SHOWS LOTS MORE SHOWER ACTIVITY JUST EAST AND
SOUTHEAST OF THE BIG ISLAND THAT IS POISED TO MOVE ONSHORE DURING
THE NEXT FEW HOURS.

HAVE UPDATED THE GRIDDED AND TEXT FORECASTS FOR PARTS OF THE EASTERN
AND INTERIOR OF THE BIG ISLAND TO ADD THE POSSIBILITY OF HEAVY
RAINFALL AND ISOLATED THUNDERSTORMS TONIGHT. OTHERWISE...THE CURRENT
FORECAST PACKAGE APPEARS TO BE ON TRACK.

&&

.PREV DISCUSSION ISSUED AT 400 PM HST..
THE HIGH FAR NORTH WILL SHIFT SLOWLY EASTWARD THROUGH THE WEEKEND.
BY LATE SUNDAY OR EARLY MONDAY A WEAK INVERTED SURFACE TROUGH MAY
SLIGHTLY WEAKEN TRADES AND TURN THEM FROM AN EAST SOUTHEAST
DIRECTION. THIS WILL BE DUE TO THE EFFECT OF AN UPPER TROUGH. WRF
MODEL HOWEVER DEPICTS MORE OF AN UNALTERED TRADE PATTERN. THE
PRESENT BREEZY CONDITIONS WILL WEAKEN SLOWLY HENCE SMALL CRAFT
ADVISORIES... GALES IN WINDIER CHANNELS AND LOCALLY GENERATED SHORT
PERIOD HIGH SURF ADVISORY ON EAST FACING SHORES. SLIGHTLY
WEAKER TRADES POSSIBLE BY SECOND HALF OF NEXT WEEK.

SCATTERED SHOWERS HAVE AFFECTED MUCH OF THE STATE WITH SIGNIFICANT
AMOUNTS MAINLY WINDWARD SIDES OF KAUAI... MAUI AND ESPECIALLY THE
BIG ISLAND. SATELLITE IMAGERY REVEALS SLIGHTLY UNSTABLE APPEARANCE
OF CLOUDS UPWIND TO THE EAST AND NORTHEAST AND WEATHER RADAR SHOWING
MAINLY LIGHT TO MODERATE SHOWERS. ISOLATED HEAVY SHOWERS MOVED
ACROSS THE BIG ISLAND IN THE EARLY AFTERNOON. VARIABLE AMOUNT OF
CIRRUS CLOUDINESS WILL CONTINUE THROUGH THE WEEKEND. A TROUGH
STRETCHING FROM AN UPPER LOW NORTHEAST OF THE ISLANDS WILL SHIFT TO
A POSITION SOUTHWEST OF THE STATE WHERE IT CAN DIRECT MOISTURE ONTO
THE ISLANDS FROM THE SOUTH. AFTERNOON BALLOON SOUNDING INDICATE THE
TRADE WIND INVERSION REMAINS ABSENT AND IS EXPECTED TO REMAIN ABSENT
INTO NEXT WEEK THUS ENHANCING TRADE WIND SHOWERS. MODELS AGREE ABOUT
INCREASED PRECIPITATION ESPECIALLY ON THE USUAL WINDWARD AND
MOUNTAIN AREAS. THESE AREAS ARE MORE GREATLY AFFECTED UNDER TRADE
WIND CONDITIONS... BUT EXPECT SHOWERS TO ALSO REACH LEEWARD AREAS
TOO. LOCALLY HEAVY SHOWERS MAY OCCUR SINCE TRADE WINDS WILL REMAIN
AT LEAST MODERATE IN STRENGTH SO THE RAPID MOVEMENT OF THE SHOWERS
PROVIDES LESS CHANCE FOR SIGNIFICANT ACCUMULATION OF RAINFALL.
COMPUTER MODELS SUGGEST THE BIG ISLAND AND PERHAPS WINDWARD MAUI MAY
BE MOST AFFECTED THROUGH THE WEEKEND AND INTO MONDAY.

WINTER WEATHER ADVISORY EXTENDED THROUGH TONIGHT. SATURDAY THERE
SHOULD BE JUST ENOUGH WARMING TO RAISE TEMPERATURES ABOVE FREEZING.

&&

.MARINE...
THE STRONG TRADE WINDS WILL CONTINUE TO PRODUCE WINDS OF GALE FORCE
IN THE PAILOLO AND ALENUIHAHA CHANNELS TONIGHT AND SATURDAY. SMALL
CRAFT ADVISORIES WILL CONTINUE FOR THE REMAINING HAWAIIAN WATERS...

BAY BUOY CONTINUE TO BE 10 FEET AND 9 SECOND THIS EVENING. SURF

INDICATED WAVE HEIGHTS AT OR JUST ABOVE THE HIGH SURF ADVISORY
THRESHOLD OF 8 FEET. DUE TO THE STRONG TRADE WINDS SOUTH OF THE HIGH
