...WESTWARD-MOVING DISTURBANCE NEAR SATAWAL TO BRING HEAVY SHOWERS  
AND STRONG GUSTS THROUGH FRIDAY...  
 
A WEAK CIRCULATION IS FOUND SOUTHEAST OF SATAWAL NEAR 6N149E AND IS  
SLOWLY MOVING WEST. IT HAS BEEN LABELED INVEST 97W BY THE JOINT  
TYPHOON WARNING CENTER AND HAS BEEN RATED A LOW FOR DEVELOPMENT  
POTENTIAL. OVERNIGHT INFRARED SATELLITE IMAGERY HAS SHOWN FLARING  
DEEP CONVECTION RESULTING IN HEAVY SHOWERS AND BURSTS OF  
THUNDERSTORMS, MOSTLY NORTH OF THE CENTER OF THIS CIRCULATION. MORE  
NOTABLY, LATE EVENING SCATTEROMETRY DATA INDICATED 30 TO 40 MPH  
EASTERLY WINDS NORTH OF THE CIRCULATION CENTER, JUST WEST OF CHUUK  
LAGOON AS THE CIRCULATION EXITED THE WENO AREA. THESE WINDS ARE THE  
RESULT OF BOTH THE WEAK CIRCULATION AND A STRONGER SURGE OF TRADE  
WINDS TO THE NORTH.  
 
WHILE MODELS INDICATE HEAVIER SHOWERS AND THUNDERSTORMS WILL CONTINUE  
TO PULSE THROUGH FRIDAY, THE BROADER CONCERN REMAINS FOCUSED ON THE  
STRONGER WINDS, GUSTS, AND THEIR EFFECT ON THE SEA STATE. AS THE  
CIRCULATION CONTINUES WESTWARD, HEAVIER SHOWERS WILL LIKELY BRING  
STRONGER GUSTS OF 30 TO 40 MPH TO SOME OF THE ISLANDS BETWEEN YAP AND  
CHUUK, MOSTLY THOSE BETWEEN 6N AND 10N. SEAS OF 5 TO 8 FEET, AS SEEN  
IN OVERNIGHT ALTIMETRY DATA, MAY LIKELY SPIKE UP TO 9 TO 12 FEET IN  
RESPONSE TO THE BURSTS OF WINDS.  
 
ALTHOUGH COMPUTER MODELS SHOW A GRADUAL DISSIPATION OF 97W IN THE  
FRIDAY-SATURDAY TIME FRAME AS IT APPROACHES 140E, RESIDENTS AND  
MARINERS ARE URGED TO KEEP AWARE OF THE LATEST FORECASTS FOR THE  
REGION AT WEATHER.GOV/GUM/PUBLICFORECASTS AND FOR MORE INFORMATION
