AREA FORECAST DISCUSSION

830 PM HST SAT MAR 3 2012

.SYNOPSIS...
UNSETTLED WEATHER WILL CONTINUE THROUGH SUNDAY...AND MAY PERSIST
THROUGH THE MIDDLE OF NEXT WEEK. LIGHT TO MODERATE EAST TO SOUTHEAST
TRADE WINDS MAY INCREASE BRIEFLY EARLY NEXT WEEK...ESPECIALLY FOR
KAUAI. A LARGE NORTH-NORTHEAST SWELL WILL PRODUCE HAZARDOUS SURF
ALONG THE WINDWARD SIDES OF THE ISLANDS BEGINNING MONDAY.

&&

.DISCUSSION...
MUCH OF THE WEATHER IS NOW FOCUS OVER KAUAI THIS EVENING...AS HEAVY
SHOWERS HAVE BEEN PASSING OVER THAT ISLAND SINCE EARLY THIS
AFTERNOON. THE WEATHER SITUATION IN KAUAI CERTAINLY BEARS A CLOSER
MONITORING AS THE GROUND IS GETTING SATURATED FROM THE RAIN AND THE
RIVER GAGES ARE SHOWING ELEVATED HEIGHTS. LATEST RADAR DATA SHOW
MORE SHOWERS HEADING TOWARDS KAUAI THIS EVENING. THERE ARE ALSO SOME
SHOWERS AFFECTING THE KAU AND KONA COASTS OF THE BIG ISLAND AT TIME.
A WINTER WINTER ADVISORY REMAINS IN EFFECT FOR THE SUMMITS OF THE
BIG ISLAND AS SNOW AND OR ICE ACCUMULATION IS STILL POSSIBLE
OVERNIGHT INTO SUNDAY. ELSEWHERE WEATHER HAS SETTLED DOWN A BIT
COMPARING TO EARLIER TODAY.

THE UNSETTLED WEATHER IS EXPECTED TO CONTINUE THROUGH SUNDAY...AS A
PERSISTENT SURFACE TROUGH REMAINS NEAR THE ISLAND VICINITY. LOOK
FOR LOCALLY HEAVY SHOWERS WITH THUNDERSTORMS POSSIBLE...ESPECIALLY
ALONG WINDWARD ZONES. A FRONT/SHEARLINE IS STILL EXPECTED TO MOVE
NEAR KAUAI MONDAY. IT WILL PROBABLY BRING INCREASING WINDS AND MORE
UNSETTLED WEATHER TO THE WESTERN PORTION OF THE STATE...ESPECIALLY
KAUAI. LATEST GFS RUN NOW INDICATES THIS FRONT/SHEARLINE MAY ADVANCE
SLOWLY FURTHER SOUTH TO NEAR MAUI COUNTY BY THE MIDDLE OF NEXT WEEK
BEFORE DISSIPATING IN THE ISLAND VICINITY. THUS AT LEAST WITH THIS
NEW SOLUTION...SOUTHERLY WINDS MAY DEVELOP OVER THE EASTERN ISLANDS
BRIEFLY ON TUESDAY. SINCE MODEL SOLUTIONS HAVE A RATHER POOR RECORD
IN CONSISTENCY FOR THIS PENDING EVENT...SHALL WAIT FOR THE LATEST
EUROPEAN MODEL BEFORE MAKING CHANGING TO THE FORECAST PACKAGE FOR
EARLY NEXT WEEK. STRONGER TRADE WINDS MAY FINALLY PUSH IN BEHIND
THIS WEAKENING SHEAR LINE BEGINNING WEDNESDAY...AND MAY STRENGTHEN
QUITE A BIT TOWARDS THE NEXT WEEKEND. MOISTURE FROM THE DISSIPATING
SHEAR LINE WILL KEEP THE ISLANDS WET AT LEAST THROUGH THE MIDDLE OF
NEXT WEEK.

&&

.AVIATION...
AN AIRMET FOR MOUNTAIN OBSCURATION CONTINUES ALL ISLANDS DUE TO
LOW CLOUDS AND SHRA.

THUNDERSTORMS HAVE BEEN PULSING AROUND THE THE STATE WITH CLOUD TOPS
OVER 30000 FEET.

&&

.MARINE...
DATA FROM BUOY FAR NORTHWEST OF THE ISLANDS INDICATE THE INCOMING
NORTHWEST SWELL MAY HAVE PEAKED EARLIER...AND NOW HAVE SWITCHED TO
A MORE NORTH DIRECTION. A HIGH SURF ADVISORY IS IN EFFECT FROM 10 PM
HST THIS EVENING FOR NORTH AND WEST OF THE SMALLER ISLANDS.
THIS SWELL WILL MAY BUILD FURTHER AS THE PERIOD DROPS
SLIGHTLY...FROM SUNDAY NIGHT INTO TUESDAY. THIS BUILDING NNE SWELL
WILL PROBABLY BRING WARNING LEVEL SURF TO THE E FACING
SHORES...WITH ADVISORY LEVEL SURF PERSISTING ALONG N FACING SHORES.
THIS HAZARDOUS SURF EPISODE IS EXPECTED TO CONTINUE THROUGH THE
MIDDLE OF NEXT WEEK.
