MARIANAS SYNOPSIS

RANGE FROM 6 TO 7 FEET AT THE BUOYS.  
 

 
   
DISCUSSION
 
 
FORECASTS REMAIN THE SAME AS DRY SEASON IS BACK IN SESSION. MODERATE  
TO FRESH TRADES WILL SLOWLY DECREASE AS HIGH PRESSURE UP NORTH SLIDES  
EASTWARD. OTHERWISE, EXCEPT FOR A SMALL INCREASE IN CLOUDS AROUND  
WEDNESDAY, LITTLE CHANGE IS EXPECTED IN OUR PRESENT PATTERN.  
 

 
   
MARINE
 
 
THE HIGH RISK OF RIP CURRENTS WILL EXTEND INTO SUNDAY BEFORE EAST  
SWELL DROPS ENOUGH LATE SUNDAY TO REDUCE THE RISK TO MODERATE.  
 

 
   
EASTERN MICRONESIA AND CHUUK
 
 
FAIR WEATHER IS IN PLACE AT CHUUK, POHNPEI AND MAJURO THIS AFTERNOON.  
AN ACTIVE WEATHER PATTERN REMAINS ACROSS MUCH OF THE REGION. VISIBLE  
SATELLITE IMAGERY SHOWS ACTIVE DEEP CONVECTION ALONG A NEAR-  
EQUATORIAL TROUGH SOUTH OF CHUUK AND POHNPEI, SHOWERS NEAR A WEAK  
DISTURBANCE OVER KOSRAE AND AN ACTIVE BAND OF TRADE WIND CONVERGENCE  
NORTH AND NORTHEAST OF MAJURO TO NEAR THE DATELINE. SHOWERS NEAR  
THE TROUGH SOUTH OF CHUUK AND POHNPEI WILL KEEP TO THE SOUTH WHILE  
DRY CONDITIONS REMAIN IN PLACE AT POHNPEI THROUGH TONIGHT AND CHUUK  
THROUGH SUNDAY NIGHT. THE DISTURBANCE NEAR KOSRAE REMAINS NEARLY  
STATIONARY BUT IS EXPECTED TO HEAD SLOWLY WEST THE NEXT FEW DAYS.  
A WET PATTERN WILL REMAIN OVER KOSRAE A COUPLE MORE DAYS. SHOWERS  
COULD BE HEAVY AT TIMES SUNDAY AND MONDAY. MODELS SHOW THIS  
DISTURBANCE WEAKENING AS IT HEAD WEST WITH SHOWERS GRADUALLY  
DISSIPATING WITHIN AN OPEN-WAVE TROUGH. WILL KEEP A CLOSE WATCH ON  
THIS. EXPECT DRY CONDITIONS AT MAJURO THROUGH SUNDAY. SHOWERS WILL  
REACH MAJURO EARLY IN THE WEEK AS TRADE-WIND CONVERGENCE INCREASES.  
 

 
   
WESTERN MICRONESIA
 
 
TRADE WINDS WERE JUST ENOUGH TO KEEP ISLAND CONVECTION OFF TO THE  
SOUTHWEST OF KOROR TODAY. DRY WEATHER IS SEEN OVER YAP WHILE ISOLATED  
SHOWERS ARE FOUND NEAR KOROR. THE DRIER WEATHER AT YAP WILL PROCEED  
TO KOROR OVERNIGHT. WENT AHEAD AND REMOVED THUNDERSTORMS FROM THE  
SUNDAY FORECAST AT KOROR AS MODERATE TRADES AND A DRY PATTERN WILL  
PERSIST. EXPECT A DRY PATTERN FOR AT LEAST THE FIRST HALF OF THE  
WEEK AT BOTH LOCATIONS.
