ABPW10 PGTW 270600 MSGID/GENADMIN/JOINT TYPHOON WRNCEN PEARL HARBOR HI// SUBJ/SIGNIFICANT TROPICAL WEATHER ADVISORY FOR THE WESTERN AND SOUTH PACIFIC OCEANS/270600Z-280600ZJUL2024// RMKS/ 1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA): A. TROPICAL CYCLONE SUMMARY: NONE. B. TROPICAL DISTURBANCE SUMMARY: (1) THE AREA OF CONVECTION (INVEST 95W) PREVIOUSLY LOCATED NEAR 6.9N 133.9E IS NOW LOCATED NEAR 7.9N 133.4E, APPROXIMATELY 80 NM WEST- NORTHWEST OF PALAU. ANIMATED VISIBLE SATELLITE IMAGERY DEPICTS A BROAD, FULLY EXPOSED LOW-LEVEL CIRCULATION (LLC) WITH DISORGANIZED CONVECTION FLARING TO THE NORTH. A 270401Z ATMS 88.2 GHZ MICROWAVE IMAGE ALSO DEPICTS A BROAD, WEAKLY-DEFINED LLC WITH NO CONVECTIVE STRUCTURE. A 270023Z ASCAT-C IMAGE SHOWS NO DEFINED CIRCULATION WITH A TROUGH OVER THE CENTER, EXTENDING NORTHWARD. ADDITIONALLY, WINDS NEAR THE CENTER ARE LIGHT (5-10 KNOTS), WITH A SWATH OF 15-20 KNOT WINDS DISPLACED OVER 200 NM TO THE NORTH-NORTHEAST. SURFACE OBSERVATIONS FROM KOROR CITY (PTRO) INDICATE SOUTH-SOUTHEASTERLY WINDS AT 5-10 KNOTS, WITH SLP NEAR 1008 MB AND A 24-HOUR SLP INCREASE OF 1 MB. UPPER-LEVEL ANALYSIS INDICATES UNFAVORABLE CONDITIONS FOR DEVELOPMENT WITH HIGH (30-35 KNOTS) NORTHERLY VERTICAL WIND SHEAR (VERIFIED FROM THE 270000Z PTRO UPPER-AIR SOUNDING) AND UPPER-LEVEL CONVERGENT FLOW. GLOBAL MODELS INDICATE NO SIGNIFICANT DEVELOPMENT OF 95W, HOWEVER, THE GLOBAL MODELS DO WEAKLY DEVELOP ANOTHER DISTURBANCE IN 12-24 HOURS FURTHER NORTH NEAR 13N 130E (NOW INVEST 96W). BOTH THE GFS AND ECMWF ENSEMBLES ALSO INDICATE A DISTURBANCE LIKELY FORMING NEAR THE NEW INVEST (96W). MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 10 TO 15 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1008 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS DOWNGRADED TO LOW. (2) NO OTHER SUSPECT AREAS. C. SUBTROPICAL SYSTEM SUMMARY: NONE. 2. SOUTH PACIFIC AREA (WEST COAST OF SOUTH AMERICA TO 135 EAST): A. TROPICAL CYCLONE SUMMARY: NONE. B.
