.EASTERN MICRONESIA... A NEAR-EQUATORIAL TROUGH EXTENDS EASTWARD FROM SOUTHWEST OF CHUUK AT 3N150E TO A BROAD TROPICAL DISTURBANCE CENTERED NEAR BUTARITARI ATOLL AT 3N173E. THE REMNANTS OF A SHEAR LINE WILL KEEP A FEW SHOWERS NEAR CHUUK AND POHNPEI TODAY. OTHERWISE DRIER TRADES NORTH OF THE NEAR-EQUATORIAL TROUGH SHOULD MAINTAIN RELATIVELY FAIR WEATHER FOR CHUUK UNTIL FRIDAY EVENING...AND POHNPEI THRU FRIDAY MORNING. FOR KOSRAE AND MAJURO...CONVECTION ASSOCIATED WITH THE TROPICAL DISTURBANCE IS EXPECTED TO PERSIST AT LEAST THRU FRIDAY. THE LARGE DOME OF HIGH PRESSURE CURRENTLY NEAR IWO TO ISLAND WILL DRIFT EASTWARD TOWARD THE DATE LINE OVER THE NEXT FEW DAYS. THIS COULD ALLOW THE TROPICAL DISTURBANCE TO GRADUALLY MOVE W-NW ON FRIDAY...CLOSER TO KOSRAE AND AWAY FROM MAJURO. ON SATURDAY... INCLEMENT WEATHER RELATED TO THE DISTURBANCE WILL REACH POHNPEI AND POSSIBLY CHUUK. ON THE OTHER HAND...IMPROVEMENT WILL SPREAD FROM MAJURO TO KOSRAE. BY EARLY NEXT WEEK...THE DISTURBANCE COULD BE FAR ENOUGH NORTHWEST OF POHNPEI AND CHUUK SO THAT A DRYING TREND IS POSSIBLE. LARGE NE SWELL GENERATED BY FRESH TO STRONG WINDS NORTH OF A SHEAR LINE WILL ARRIVE AT CHUUK STATE EASTWARD TO KOSRAE TODAY. THEREFORE ANTICIPATE SURF REACHING HAZARDOUS LEVELS LATER THIS AFTERNOON AT THESE LOCATIONS. THIS SAME NE SWELL COULD ALSO COMBINE WITH TRADE-WIND SWELL AND WIND WAVES TO PRODUCE HIGH SURF ACROSS THE MARSHALL ISLANDS BY FRIDAY MORNING. && .WESTERN MICRONESIA... REASONING FOR THE CHUUK FORECAST IS INCLUDED IN THE EASTERN MICRONESIA DISCUSSION ABOVE DUE TO A SIMILAR SYNOPTIC PATTERN. SURFACE WINDS NEAR PALAU AND YAP ARE VEERING TO THE EAST AS THE HIGH CONTINUES TO SLIDE EASTWARD AWAY FROM IWO TO ISLAND. THIS SHOULD CAUSE THE WESTERN PORTION OF THE SHEAR LINE TO WEAKEN NEAR YAP AND PROMOTE MAINLY DRY WEATHER FOR THE NEXT SEVERAL DAYS. FOR KOROR...A WEAK SURFACE TROUGH WILL SQUEEZE OUT SOME SHOWERS TODAY. THEN A FEW MORE WEAK DISTURBANCES FROM UPSTREAM NEAR CHUUK MIGHT SPARK OFF MORE SHOWERS THRU FRIDAY. BY THIS WEEKEND...ANOTHER RIDGE OF HIGH PRESSURE MOVING OFF THE EAST CHINA COAST COULD FINALLY BRING MORE STABLE CONDITIONS FOR BOTH LOCALES. AFTERWARD...THE TROPICAL DISTURBANCE CURRENTLY SOUTH OF MAJURO MIGHT PAY A VISIT TO THE AREA. LINGERING NORTHEAST SWELL WILL PROLONG HIGH SURF ACROSS YAP STATE AND THE REPUBLIC OF PALAU UNTIL SATURDAY. IT WILL ALSO GENERATE SEA CONDITIONS HAZARDOUS TO SMALL CRAFT THRU FRIDAY NIGHT.
