TROPICAL CYCLONE ADVISORY: ABPW10 PGTW 121900 MSGID/GENADMIN/JOINT TYPHOON WRNCEN PEARL HARBOR HI// SUBJ/SIGNIFICANT TROPICAL WEATHER ADVISORY FOR THE WESTERN AND SOUTH PACIFIC OCEANS REISSUED/121900Z-130600ZSEP2026// REF/A/MSG/JOINT TYPHOON WRNCEN PEARL HARBOR HI/121321ZSEP2026// AMPN/REF A IS A TROPICAL CYCLONE FORMATION ALERT.// 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 98W) PREVIOUSLY LOCATED NEAR 17.0N 109.1E IS NOW LOCATED NEAR 17.1N 108.5E, APPROXIMATELY 67 NM NORTH-NORTHEAST OF DA NANG VIETNAM. ANIMATED ENHANCED INFRARED (EIR) DEPICTS A BROAD AREA OF DISORGANIZED DEEP CONVECTION ASSOCIATED WITH A SLOWLY CONSOLIDATING LOW-LEVEL CIRCULATION CENTER (LLCC). THE LLCC REMAINS BROAD AND ELONGATED, WITH THE WESTERN EXTENT OF THE CIRCULATION LIKELY EXTENDING OVER LAND. CURRENT ANALYSIS OF THE SURROUNDING ENVIRONMENT INDICATES FAVORABLE CONDITIONS FOR FURTHER CONSOLIDATION WITH LOW (10-15 KTS) VERTICAL WIND SHEAR, STRONG EQUATORWARD OUTFLOW ALOFT, WARM (28-29 C) SEA SURFACE TEMPERATURES, AND DEEP MOISTURE THROUGHOUT THE AIR COLUMN BEING OFFSET BY LAND INTERACTION. GLOBAL DETERMINISTIC MODELS ARE IN GOOD AGREEMENT THAT 98W WILL TRACK GENERALLY NORTHWESTWARD, SKIRTING THE COAST OF VIETNAM, POTENTIALLY REACHING TROPICAL DEPRESSION CRITERIA DURING THE NEXT 12- 24 HOURS. THERE REMAINS SIGNIFICANT UNCERTAINTY AS TO WHETHER THE BROAD SYSTEM CAN ORGANIZE BEFORE IT MAKES LANDFALL IN VIETNAM AND TRANSITS INLAND. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 23 TO 28 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1006 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS HIGH. (2) AN AREA OF CONVECTION (INVEST 90W) HAS PERSISTED NEAR 12.5N 156.6E, APPROXIMATELY 416 NM NORTHEAST OF CHUUK. ANIMATED ENHANCED INFRARED IMAGERY (EIR) DEPICTS A BROAD AREA OF CYCLONIC ROTATION SITUATED ON A WEST-TO-EAST ORIENTED TROUGH, WITH CYCLING DEEP CONVECTION ALONG THE SOUTHERN AND EASTERN PERIPHERY. ENVIRONMENTAL CONDITIONS ARE MOSTLY FAVORABLE WITH WARM (28-29C) SEA SURFACE TEMPERATURES, GOOD POLEWARD OUTFLOW, LOW TO MODERATE (15-20KT) VERTICAL WIND SHEAR, AND DRY AIR TO THE NORTH. GLOBAL MODELS ARE IN AGREEMENT THAT THE INVEST 90W WILL SLOWLY CONSOLIDATE OVER THE NEXT 36-48 HOURS AND TRACK GENERALLY NORTH-NORTHWESTWARD AS THE CONVECTION AND WINDS BUILD. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 13 TO 18 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1007 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS LOW. (3) 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: ADDED LOW AREA IN PARA 1.B.(2)// NNNN

1 Rain season in the Philippines: June 1st to Oct 31st.   5 Estimated amount of water needed to replace the water used by plants and evaporation from the past week. (Negative numbers mean amount of water needed, positive numbers mean excess water is present).   6 Air Quality Index is provided by Luftdaten System esp8266 and is updated every 5 mins..   9 Solar Index represents either an absolute scale of solar energy (W/m²) using the station’s recorded maximum or a percentage of computed theoretical solar maximum using the station’s location and time of day. These indices differ most when the sun is low on the horizon. The current scale is shown, and will toggle if it or the icon is clicked.   10 Historical average only to day 13 of just the month of September for this station since 2016.   11 Historical average rain this season to day 13 of September for this station since 2016.
