ABPW10 PGTW 061830 MSGID/GENADMIN/JOINT TYPHOON WRNCEN PEARL HARBOR HI// SUBJ/SIGNIFICANT TROPICAL WEATHER ADVISORY FOR THE WESTERN AND SOUTH PACIFIC OCEANS REISSUED/061830Z-070600ZDEC2025// REF/A/MSG/JOINT TYPHOON WRNCEN PEARL HARBOR HI/061821ZDEC2025 AMPN/ REF A IS A TROPICAL CYCLONE FORMATION ALERT CANCELLATION.// RMKS/ 1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA): A. TROPICAL CYCLONE SUMMARY: NONE. B. TROPICAL DISTURBANCE SUMMARY: (1) THE AREA OF CONVECTION (INVEST 93W) PREVIOUSLY LOCATED NEAR 12.0N 125.8E IS NOW LOCATED NEAR 12.3N 125.2E, APPROXIMATELY 97 NM EAST- SOUTHEAST OF LEGAZPI. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY (EIR) DEPICTS A FULLY EXPOSED AND RAGGED LOW-LEVEL CIRCULATION CENTER (LLCC) WITH WEAKENED CONVECTION DISPLACED WEST OF THE LLCC. ANALYSIS OF THE ENVIRONMENT INDICATES THE SYSTEM HAS DRIFTED INTO AN AREA OF HIGH VERTICAL WIND SHEAR (25-30 KTS). SEA SURFACE TEMPERATURES REMAIN WARM (29-30 C). DRY AIR ENTRAINMENT CAN BE ANALYZED TO THE EAST OF 93W. ADDITIONALLY, THE LLCC IS APPROACHING LAND, RESULTING IN INCREASED FRICTIONAL EFFECTS ON THE CIRCULATION. GLOBAL DETERMINISTIC MODELS AND ENSEMBLES ARE IN GOOD AGREEMENT THAT 93W WILL CROSS OVER THE PHILIPPINES, BUT WILL STRUGGLE TO CONSOLIDATE AS IT INTERACTS WITH THE COLD SURGE ONCE IT MOVES INTO THE SOUTH CHINA SEA. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 18 TO 23 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1005 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS DOWNGRADED TO MEDIUM. SEE REF A (WTPN21 PGTW 061830) FOR FURTHER DETAILS. (2) NO OTHER SUSPECT AREAS. C. SUBTROPICAL SYSTEM SUMMARY: NONE. 2. SOUTH PACIFIC AREA (WEST COAST OF SOUTH AMERICA TO 135 EAST): A. TROPICAL CYCLONE SUMMARY: NONE. B. TROPICAL DISTURBANCE SUMMARY: NONE. C. SUBTROPICAL SYSTEM SUMMARY: NONE. 3. JUSTIFICATION FOR REISSUE: DOWNGRADED AREA IN PARA. 1.B.(1). TO MEDIUM.// NNNN
