AREA FORECAST DISCUSSION FOR AMERICAN SAMOA AND INDEPENDENT SAMOA
NATIONAL WEATHER SERVICE PAGO PAGO AS
118 PM SST FRI AUG 29 2014

.SHORT TERM (TONIGHT THROUGH SUNDAY NIGHT)...
VERY LITTLE CHANGE IN THE FORECAST AS THE STRONG HIGH PRESSURE
SYSTEM REMAINS FAR SOUTH OF THE TERRITORY...COMBINED WITH THE
STATIONARY FRONT ORIENTED NORTH OF THE SAMOAN ISLANDS CONTINUE TO
DOMINATE WEATHER CONDITIONS ACROSS THE AREA. THE BREEZY EASTERLIES
WILL PREVAIL THROUGH THE SHORT TERM AS MINIMAL CHANGE IN PRESSURE
GRADIENTS IS EXPECTED. ADDITIONALLY...EXPECT PERIODS OF SHOWERS TO
BE EMBEDDED WITHIN THE EASTERLY FLOW.

.LONG TERM (MONDAY THROUGH FRIDAY)...
THE AFOREMENTIONED HIGH PRESSURE SYSTEM IS DEPICTED TO DRIFT
EASTWARD THROUGH THE LONG TERM. IT WILL STILL KEEP THE PERSISTENT
STRONG WINDS ACROSS THE ISLANDS. HOWEVER...LATEST SOLUTIONS SHOW A
SLIGHT DECREASE AS THE HIGH PRESSURE SYSTEM SLIGHTLY WEAKENS...AND
THE AFOREMENTIONED FRONT SHIFTS SLIGHTLY TO THE NORTHEAST. BY
THURSDAY...GLOBAL MODELS SHOW THE AFOREMENTIONED HIGH PRESSURE
SYSTEM RE-STRENGTHENING AND THE FRONT REBUILDING CLOSE TO THE WESTERN
SAMOAN ISLANDS. THUS...BRINGING A SLIGHT UPTICK IN SHOWERS...AND
TIGHTENING THE PRESSURE GRADIENT ACROSS THE AREA...CAUSING A
SLIGHT INCREASE IN SOUTHEASTERLIES.

&&

.MARINE...
LATEST WAVE WATCH III SOLUTIONS SHOW THE SOUTHEAST SWELL GRADUALLY
DIMINISHING LATE TONIGHT...EXPECTED TO FALL BELOW ADVISORY
THRESHOLDS FOR HIGH SURF BY SUNDAY. WILL CONTINUE THE HIGH SURF
