"ABIO10 PGTW 030630\r\nMSGID/GENADMIN/JOINT TYPHOON WRNCEN PEARL HARBOR HI//\r\nSUBJ/SIGNIFICANT TROPICAL WEATHER ADVISORY FOR THE INDIAN OCEAN \r\nREISSUED/030630Z-031800ZMAR2026//\r\nAMPN/REF A IS A TROPICAL CYCLONE FORMATION ALERT.// \r\nRMKS/\r\n   B. TROPICAL DISTURBANCE SUMMARY: NONE.\r\n   C. SUBTROPICAL SYSTEM SUMMARY: NONE.\r\n   B. TROPICAL DISTURBANCE SUMMARY:\r\n      (1) THE AREA OF CONVECTION (INVEST 93S) PREVIOUSLY LOCATED NEAR \r\n17.6S 122.4E IS NOW LOCATED NEAR 17.1S 122.6E, APPROXIMATELY 54 NM \r\nSOUTH-SOUTHWEST OF BROOME. ENHANCED INFRARED SATELLITE IMAGERY DEPICTS \r\nREVEALS A BROAD DISORGANIZED REGION OF TROFING ALONG THE NORTHWESTERN \r\nCOAST OF AUSTRALIA. ANALYSIS OF SURFACE OBSERVATIONS FROM BROOME \r\nSUGGEST THE TROF AXIS, OR POTENTIAL DEVELOPING ROTATION, PASSED NORTH \r\nOF THE STATION AT APPROXIMATELY 1200Z AND HAS NOW MOVED OVER WATER. \r\nDISORGANIZED CONVECTION CONTINUES TO DEVELOP ALONG THE NORTHERN \r\nPERIPHERY OF THE CIRCULATION. ENVIRONMENTAL ANALYSIS REVEALS \r\nMODERATELY FAVORABLE CONDITIONS FOR DEVELOPMENT WITH HIGH VERTICAL \r\nWIND SHEAR (20 TO 30KTS), VERY WARM NEARBY SEA SURFACE TEMPERATURES \r\n(30 TO 31 C), AND MODERATE POLEWARD OUTFLOW. GLOBAL DETERMINISTIC AND \r\nENSEMBLE MODELS PREDICT GRADUAL DEVELOPMENT AS IT TRANSITS WESTWARD \r\nOVER THE NEXT 48-72 HOURS MAXIMUM SUSTAINED SURFACE WINDS ARE \r\nESTIMATED AT 18 TO 23 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED \r\nTO BE NEAR 1002 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT \r\nTROPICAL CYCLONE WITHIN THE NEXT 24 HOURS REMAINS LOW.\r\n      (2) THE AREA OF CONVECTION (INVEST 90S) PREVIOUSLY LOCATED \r\nNEAR 11.0S 105.5E IS NOW LOCATED NEAR 11.8S 107.5E, APPROXIMATELY 135 \r\nNM SOUTHEAST OF CHRISTMAS ISLAND. ANIMATED MULTISPECTRAL SATELLITE \r\nIMAGERY DEPICTS A CONSOLIDATING PARTIALLY OBSCURED LOW LEVEL \r\nCIRCULATION CENTER WITH CONVECTIVE BANDING ALONG THE SOUTHERN \r\nPERIPHERY. A 030227Z ASCAT PASS SHOWS A SWATH OF 25-30 KT WINDS ALONG \r\nTHE EASTERN PERIPHERY. ENVIRONMENTAL ANALYSIS REVEALS A FAVORABLE \r\nENVIRONMENT FOR DEVELOPMENT WITH STRONG EQUATORWARD OUTFLOW, LOW TO \r\nMODERATE VERTICAL WIND SHEAR (15-20 KTS), AND WARM SEA SURFACE \r\nTEMPERATURES (28-29 C). GLOBAL MODELS SHOW 90S TRACKING EASTWARD AS IT \r\nCONSOLIDATES OVER THE NEXT 24-48 HOURS. MAXIMUM SUSTAINED SURFACE \r\nWINDS ARE ESTIMATED AT 28 TO 33 KNOTS. MINIMUM SEA LEVEL PRESSURE IS \r\nESTIMATED TO BE NEAR 998 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A \r\nSIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS UPGRADED TO \r\nHIGH. SEE REF A (WTXS21 PGTW 030630) FOR FURTHER DETAILS.\r\n      (3) NO OTHER SUSPECT AREAS.\r\n   C. SUBTROPICAL SYSTEM SUMMARY: NONE.\r\n3. JUSTIFICATION FOR REISSUE: UPGRADED AREA IN PARA. 2.B.(2) TO \r\nHIGH.//"
