210 PM SST FRI AUG 22 2014

.SHORT TERM...
TONIGHT THROUGH SUNDAY NIGHT...SATELLITE IMAGERIES SHOW A SLOW
MOVING SHEARLINE TO THE NEAR SOUTH OF THE ISLANDS. ANOTHER
SIGNIFICANT WEATHER FEATURE THAT WILL IMPACT THE SHORT TERM IS THE
STRONG HIGH PRESSURE SYSTEM TO THE FAR SOUTHWEST OR SOUTH OF FIJI.
RAOB FROM THIS AFTERNOON DEPICTS A STABLE PROFILE. ALL MODELS
AGREED IN MIGRATING THE SHEARLINE TO THE NORTHEAST...PASSING THE
ISLAND CHAIN ON SATURDAY EVENING. HOWEVER...SOME MINIMIZE SHOWERS TO
ISOLATED WHILE OTHERS MATERIALIZE SHOWERS TO SCATTERED ON
SATURDAY. WINDS WILL BE FROM THE SOUTH AS THE SHEARLINE MOVES OVER
THE ISLANDS TONIGHT. HIGH THE FAR SOUTHWEST WILL AGAIN GENERATE
BREEZY AND GUSTY SOUTH WINDS SATURDAY AND THE REST OF THE WEEKEND.
THEREFORE...EXPECT ISOLATED SHOWERS EXCEPT FOR SATURDAY WITH
SCATTERED RAINFALLS. WINDS WILL GRADUALLY INCREASE TO BREEZY
CONDITIONS ON SATURDAY MORNING AND PERSIST THROUGH THE NEW WEEK.

.LONG TERM...
MONDAY THROUGH FRIDAY...THE SHEARLINE WILL REMAIN NEARLY
STATIONARY TO THE NORTHEAST DURING MOST OF THE WEEK. STRONG HIGH
PRESSURE TO SOUTH WILL CONTINUE TO GENERATE BREEZY TO STRONG SOUTH
TO SOUTHEAST WINDS. REMNANTS FROM THE SHEARLINE ARE NOW EXPECTED
TO DESCEND OVER THE ISLANDS LATE DURING THE NEW WEEK. WILL AMEND
THE PREVIOUS FCST TO REFLECT NEW OUTLOOKS.

&&

.MARINE...
SEAS WILL BUILD 6 TO 8 FT TONIGHT BEFORE RISING 7 TO 9 FT ON
SATURDAY. MODELS HAVE AGAIN BUILT SEAS 9 TO 12 FT ON SATURDAY
NIGHT AND PERSIST THROUGHOUT THE FCST PERIOD. THEREFORE...SMALL
CRAFT ADVISORY IS NOW IN EFFECT AND THE ISSUANCE OF A HIGH SURF
ADVISORY SATURDAY MORNING.
