157 PM SST MON OCT 20 2014

.SHORT TERM...
TONIGHT THROUGH WEDNESDAY NIGHT...LATEST SOLUTIONS HAVE DIVERGED
SLIGHTLY FROM PREVIOUS SOLUTIONS...NOW SHOWING A SURFACE RIDGE
DOMINATING WEATHER CONDITIONS ACROSS THE SAMOAN ISLANDS THROUGH
THE SHORT TERM. THIS SURFACE RIDGE IS EXPECTED TO PREVENT THE BULK
OF MOISTURE ASSOCIATED WITH A SURFACE TROUGH TO THE NORTH AND WEST
OF AMERICAN SAMOA...KEEPING IT FROM REACHING THE TERRITORY.
HENCE...BENIGN WEATHER WITH LIGHT TO MODERATE EASTERLIES WILL
PREVAIL THROUGHOUT THE SHORT TERM.

.LONG TERM...
THURSDAY THROUGH MONDAY...LIGHT AND VARIABLE WINDS AND PERIODS OF
INCREASING MOISTURE AND CLOUDINESS IS LIKELY THROUGHOUT THE LONG
TERM...AS A SURFACE TROUGH TO THE WEST OF THE TERRITORY NEARS THE
ISLANDS...AND THE AFOREMENTIONED RIDGE MOVES FURTHER EAST.
HOWEVER...UNLIKE PREVIOUS SOLUTIONS...THE BULK OF THE MOISTURE
ASSOCIATED WITH THIS TROUGH WILL BE MOSTLY CONCENTRATED TO THE
SOUTH OF THE ISLANDS RATHER THAN OVER THE SAMOAN ISLANDS...AS A
WEAK LOW FORMS NEAR FIJI AND MIGRATE SOUTHEAST. LIGHT TO MODERATE
EASTERLIES ARE EXPECTED TO RETURN BY THE END OF THE LONG TERM AS
ANOTHER HIGH PRESSURE STRENGTHENS FAR SOUTH AND MOVE EAST.

.MARINE...
SEAS WILL REMAIN ABOVE ADVISORY THRESHOLDS FOR HIGH SURF AND SMALL
CRAFTS THROUGH TUESDAY NIGHT. THE GRADUAL DIMINISHING HEIGHTS WILL
REMAIN BELOW ADVISORY LEVELS FROM WEDNESDAY THROUGH SATURDAY.
