.SHORT TERM...
TONIGHT THROUGH WEDNESDAY NIGHT...MODERATE TO FRESH TRADES WILL
CONTINUE TO PREVAIL ACROSS THE SAMOAN ISLANDS THROUGH MIDWEEK.
THESE CONDITIONS ARE LARGELY DUE TO MULTIPLE HIGH PRESSURE SYSTEMS
PASSING SOUTH OF THE ISLANDS FROM WEST TO EAST. LATEST SATELLITE
IMAGERY SHOWS ISOLATED TO SCATTERED SHOWERS EMBEDDED WITHIN THE
TRADE WIND FLOW WHILE A SURFACE TROUGH REMAINS NEARLY STATIONARY
TO THE NORTH OF THE ISLANDS. MODEL SOLUTIONS ARE CONSISTENT WITH
PREVIOUS OUTPUTS. HENCE...WILL KEEP PREVIOUS FORECAST.

.LONG TERM...
THURSDAY THROUGH MONDAY...LATEST MODEL SOLUTIONS CONTINUE TO AGREE
WITH PAST SOLUTIONS WITH MOVING THE AFOREMENTIONED TROUGH OVER THE
TERRITORY...BRINGING AN UPTICK IN SHOWERS AND CLOUDS. HOWEVER...THERE
IS A SLIGHT DIFFERENCE ON THE ACTUAL TIME OF ARRIVAL. HENCE...WILL
KEEP PREVIOUS FORECAST AND CONTINUE TO MONITOR FUTURE MODEL SOLUTIONS.

&&

.MARINE...
OBSERVATIONS AT THE AUNUU WAVE BUOY ARE RECORDING HIGHER WAVE
HEIGHTS AS COMPARED TO THE WAVE WATCH SOLUTIONS. THESE HEIGHTS ARE
STILL WITHIN THE ADVISORY THRESHOLDS...BUT WILL SLIGHTLY ADJUST IT
UPWARD TO REFLECT CURRENT OBSERVATIONS. SEAS AND WINDS WILL
CONTINUE TO MAINTAIN ADVISORY CRITERIA FOR BOTH HIGH SURFS AND
SMALL CRAFTS THROUGH AT LEAST THURSDAY AS MULTIPLE SOUTHERLY
