"ABPW10 PGTW 060930\r\nMSGID/GENADMIN/JOINT TYPHOON WRNCEN PEARL HARBOR HI//\r\nSUBJ/SIGNIFICANT TROPICAL WEATHER ADVISORY FOR THE WESTERN AND SOUTH \r\nPACIFIC OCEANS REISSUED/060930Z-070600ZAUG2024//\r\nREF/A/JOINT TYPHOON WRNCEN PEARL HARBOR HI/060851ZAUG2024//\r\nAMPN/REF A IS A TROPICAL CYCLONE FORMATION ALERT.//\r\nRMKS/\r\n   B. TROPICAL DISTURBANCE SUMMARY:\r\n      (1) THE AREA OF CONVECTION (INVEST 91W) PREVIOUSLY LOCATED NEAR \r\n24.2N 131.6E IS NOW LOCATED NEAR 24.1N 126.6E, APPROXIMATELY 150 NM \r\nSOUTH-SOUTHWEST OF KADENA AB, OKINAWA. THIS VERY LARGE SYSTEM IS \r\nLOCATED WITHIN THE WESTERN PERIPHERY OF THE MONSOON GYRE, WHICH \r\nREMAINS ENTRENCHED OVER THE WESTERN NORTH PACIFIC, WITH AN EXTENSIVE \r\nSWATH OF 15-25 KNOT WEST-SOUTHWESTERLY TO SOUTHWESTERLY WINDS FROM \r\nTHE EAST PHILIPPINE SEA TO ABOUT 145E. SURFACE WINDS ACROSS THIS \r\nREGION RANGE FROM 10-15 KNOTS, REFLECTING THE OVERALL WEAK NATURE OF \r\nTHIS SYSTEM. ANIMATED MULTISPECTRAL SATELLITE IMAGERY DEPICTS SEVERAL \r\nMESOVORTICES (23.1N 126.8E, 25.1N 126.8E, 24.6N 122.7E) ROTATING \r\nCYCLONICALLY AROUND THE CENTROID, WHICH REPRESENTS THE LOW-LEVEL \r\nCIRCULATION CENTER (LLCC). A 060442Z AMSR2 36 GHZ COLOR COMPOSITE \r\nMICROWAVE IMAGE INDICATES WEAK CONVECTIVE STRUCTURE, WITH ISOLATED \r\nCONVECTIVE BURSTS OVER THE WESTERN PERIPHERY. UPPER-LEVEL ANALYSIS \r\nINDICATES MARGINAL CONDITIONS, WITH WEAK DIFFLUENCE ALOFT AND LOW TO \r\nMODERATE (10-20 KNOTS) VERTICAL WIND SHEAR. SST VALUES ARE CONDUCIVE \r\n(30-31 C); HOWEVER, EXTENSIVE DRY AIR ENTRAINMENT IS HINDERING \r\nDEVELOPMENT. GLOBAL MODELS INDICATE A QUASI-STATIONARY TRACK MOTION \r\nSOUTH OF OKINAWA OVER THE NEXT TWO DAYS WITH NO SIGNIFICANT \r\nDEVELOPMENT. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 12 TO \r\n17 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1002 MB. \r\nTHE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE \r\nWITHIN THE NEXT 24 HOURS REMAINS LOW. \r\n      (2) THE AREA OF CONVECTION (INVEST 94W) PREVIOUSLY LOCATED \r\nNEAR 26.3N 141.2E IS NOW LOCATED NEAR 26.5N 140.9E, APPROXIMATELY 106 \r\nNM NORTH-NORTHWEST OF IWO-TO. THIS DISTURBANCE IS LOCATED ALONG THE \r\nEASTERN PERIPHERY OF THE MONSOON GYRE. ANIMATED MULTISPECTRAL \r\nSATELLITE IMAGERY DEPICTS A CONSOLIDATING LOW-LEVEL CIRCULATION \r\n(LLC), WITH IMPROVED CONVECTIVE BANDING WRAPPING INTO THE CENTER. A \r\n060601Z TMS (TROPICS) 91 GHZ MICROWAVE IMAGE REVEALS CURVED DEEP \r\nCONVECTIVE BANDING OVER THE SOUTHERN SEMICIRCLE OF THE LLC. SURFACE \r\nWINDS FROM IWO-TO INDICATE STEADY WEST-SOUTHERLY SUSTAINED WINDS AT \r\n10-15 KNOTS WITH A SLP VALUE NEAR 1001 MB AND A 2 MB SLP DECREASE \r\nOVER THE PAST 24 HOURS. ENVIRONMENTAL CONDITIONS ARE FAVORABLE WITH \r\nRADIAL OUTFLOW AND LOW VERTICAL WIND SHEAR. GLOBAL MODELS INDICATE A \r\nSLOW NORTHWARD TRACK WITH STEADY CONSOLIDATION OVER THE NEXT TWO DAYS \r\nAS THE SYSTEM TRACKS ALONG THE EASTERN PERIPHERY OF THE MONSOON GYRE. \r\nMAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 20 TO 25 KNOTS. \r\nMINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1000 MB. THE \r\nPOTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE \r\nWITHIN THE NEXT 24 HOURS IS UPGRADED TO HIGH. SEE REF A (WTPN21 PGTW \r\n060900) FOR FURTHER DETAILS.\r\n      (3) NO OTHER SUSPECT AREAS.\r\n   B. TROPICAL DISTURBANCE SUMMARY: NONE."
