"ABPW10 PGTW 240900\r\nMSGID/GENADMIN/JOINT TYPHOON WRNCEN PEARL HARBOR HI//\r\nSUBJ/SIGNIFICANT TROPICAL WEATHER ADVISORY FOR THE WESTERN AND SOUTH \r\nPACIFIC OCEANS REISSUED/240900Z-250600ZSEP2024//\r\nREF/A/MSG/JOINT TYPHOON WRNCEN PEARL HARBOR HI/240751ZSEP024//\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 94W) PREVIOUSLY LOCATED \r\nNEAR 27.7N 134.0E IS NOW LOCATED NEAR 27.8N 134.2E, APPROXIMATELY 395 \r\nNM SOUTHEAST OF SASEBO, JAPAN. ANIMATED MULTISPECTRAL SATELLITE \r\nIMAGERY SHOWS A SLOWLY CONSOLIDATING PARTIALLY-EXPOSED, WELL-DEFINED \r\nLOW-LEVEL CIRCULATION (LLC) WITH INCREASING CORE CONVECTION. A 240432Z \r\nCOWVR COLOR COMPOSITE 34 GHZ MICROWAVE IMAGE REVEALS CONVECTIVE \r\nBANDING WRAPPING TIGHTLY INTO A DEFINED LOW-LEVEL CIRCULATION CENTER. \r\n94W IS LOCATED POLEWARD OF A SUBTROPICAL RIDGE AXIS AND EQUATORWARD OF \r\nA STATIONARY FRONT. UPPER-LEVEL ANALYSIS INDICATES RIDGING ALOFT WITH \r\nWEAK DIFFLUENCE. THE ENVIRONMENT IS CONDUCIVE FOR FURTHER DEVELOPMENT \r\nWITH WARM SEA SURFACE TEMPERATURES (27-29C) AND LOW-TO-MODERATE \r\nVERTICAL WIND SHEAR OF 15-20 KNOTS. HOWEVER, THE CONDITIONS ARE \r\nCONSIDERED MARGINALLY FAVORABLE DUE TO ITS CLOSE PROXIMITY TO THE \r\nWESTERLIES AND ASSOCIATED DRY AIR. GLOBAL MODELS INDICATE A GENERALLY \r\nSLOW, ERRATIC TRACK THROUGH TAU 48 WITHIN A WEAK STEERING ENVIRONMENT. \r\nAFTER TAU 48, THE SYSTEM IS EXPECTED TO ACCELERATE POLEWARD TOWARD \r\nCENTRAL JAPAN, WITH GRADUAL TRANSITION TO A SUBTROPICAL CYCLONE AS THE \r\nSYSTEM TRACKS UNDER STRENGTHENING UPPER-LEVEL SOUTHWESTERLY FLOW. \r\nMAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 20 TO 25 KNOTS.\r\nMINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1003 MB. THE\r\nPOTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE\r\nWITHIN THE NEXT 24 HOURS IS UPGRADED HIGH. SEE REF A (WTPN21 PGTW \r\n240800) FOR FURTHER DETAILS.\r\n      (2) NO OTHER SUSPECT AREAS.\r\n   B. TROPICAL DISTURBANCE SUMMARY: NONE."
