"ABPW10 PGTW 280600\r\nMSGID/GENADMIN/JOINT TYPHOON WRNCEN PEARL HARBOR HI//\r\nSUBJ/SIGNIFICANT TROPICAL WEATHER ADVISORY FOR THE WESTERN AND SOUTH \r\nPACIFIC OCEANS/280600Z-290600ZAUG2025//\r\nREF/A/MSG/JOINT TYPHOON WRNCEN PEARL HARBOR HI//280321ZAUG2025//\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 93W) PREVIOUSLY LOCATED NEAR \r\n14.5N 116.1E IS NOW LOCATED NEAR 14.9N 115.9E, APPROXIMATELY 449 NM \r\nEAST OF DA NANG, VIETNAM. BASED ON RECENT SATELLITE IMAGERY AND ASCAT \r\nDATA, THE SYSTEM HAS QUICKLY TRANSITIONED FROM A MONSOON DEPRESSION TO \r\nA TROPICAL DEPRESSION. ANIMATED MULTISPECTRAL SATELLITE IMAGERY (MSI) \r\nAND A 272318Z SSMIS 37GHZ MICROWAVE IMAGE DEPICT IMPROVED CONVECTIVE \r\nBANDING OVER THE WESTERN SEMICIRCLE WRAPPING INTO THE CONSOLIDATING LOW \r\nLEVEL CIRCULATION. MSI ALSO SHOWS A BROAD, EXPOSED CENTER, WITH \r\nMULTIPLE MESOVORTICIES ROTATING CYCLONICALLY AROUND A CENTROID. A \r\n280059Z ASCAT-B IMAGE REVEALS A BROAD CENTER, WITH 25-30 KNOT WINDS \r\nDISPLACED ABOUT 70-75NM TO THE SOUTH, WHICH IS MORE TYPICAL OF TROPICAL \r\nSYSTEMS. ENVIRONMENT ANALYSIS REVEALS MARGINALLY FAVORABLE CONDITIONS \r\nWITH MODERATE TO HIGH VERTICAL WIND SHEAR 20-25 KNOTS OFFSET BY ROBUST \r\nWESTWARD OUTFLOW ALOFT AND WARM 28-29 C SEA SURFACE TEMPERATURES (SST). \r\nGLOBAL MODELS ARE SHOWING STEADY DEVELOPMENT WITH A NORTHWESTWARD TRACK \r\nOVER THE NEXT 24 HOURS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT \r\n25 TO 30 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1002 \r\nMB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE \r\nWITHIN THE NEXT 24 HOURS REMAINS HIGH. SEE REF A (WTPN21 PGTW 280330) \r\nFOR FURTHER DETAILS.\r\n      (2) NO OTHER SUSPECT AREAS.\r\n   C. SUBTROPICAL SYSTEM SUMMARY: NONE.\r\n   B. TROPICAL DISTURBANCE SUMMARY: NONE.\r\n   C. SUBTROPICAL SYSTEM SUMMARY: NONE.//"
