"ABPW10 PGTW 141600\r\nMSGID/GENADMIN/JOINT TYPHOON WRNCEN PEARL HARBOR HI//\r\nSUBJ/SIGNIFICANT TROPICAL WEATHER ADVISORY FOR THE WESTERN AND SOUTH \r\nPACIFIC OCEANS REISSUED/141600Z-150600ZJUL2024//\r\nREF/A/MSG/JOINT TYPHOON WRNCEN PEARL HARBOR HI/141521ZJUL2024//\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 99W) PREVIOUSLY LOCATED NEAR \r\n15.3N 111.1E IS NOW LOCATED NEAR 15.1N 110.9E, APPROXIMATELY 167 NM \r\nEAST-SOUTHEAST OF DA NANG, VIETNAM. ANIMATED ENHANCED INFRARED \r\nSATELLITE IMAGERY AND A 141050Z SSMIS 91 GHZ MICROWAVE IMAGE DEPICT \r\nDISORGANIZED, FLARING DEEP CONVECTION OVER A BROAD LOW-LEVEL CIRCULATION \r\nCENTER. HOWEVER, A 141325Z ASCAT-B BULLSEYE IMAGE DEPICTS A SYMMETRIC, \r\nSIGNIFICANTLY IMPROVED CIRCULATION WITH 20-25 KNOT WINDS. UPPER-LEVEL \r\nANALYSIS INDICATES A MARGINAL ENVIRONMENT, WITH PERSISTENT EAST-\r\nNORTHEASTERLY FLOW OVER THE CORE OFFSET SLIGHTLY BY MODERATE \r\nEQUATORWARD OUTFLOW. HOWEVER, VERTICAL WIND SHEAR REMAINS MODERATE TO \r\nHIGH (20-30 KNOTS), WHICH IS HINDERING CONVECTIVE DEVELOPMENT. SEA \r\nSURFACE TEMPERATURES OF 29-30 C ARE CONDUCIVE. GLOBAL MODELS INDICATE \r\nA WEST-NORTHWESTWARD TO NORTHWESTWARD TRACK OVER VIETNAM OVER THE NEXT \r\n24 HOURS WITH GRADUAL DEVELOPMENT INTO A WEAK TROPICAL DEPRESSION. \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 WITHIN \r\nTHE NEXT 24 HOURS IS UPGRADED TO HIGH. SEE REF A (WTPN21 PGTW 141530) \r\nFOR FURTHER DETAILS.\r\n      (2) NO OTHER SUSPECT AREAS.\r\n   B. TROPICAL DISTURBANCE SUMMARY: NONE."
