ABPW10 PGTW 140600 MSGID/GENADMIN/JOINT TYPHOON WRNCEN PEARL HARBOR HI// SUBJ/SIGNIFICANT TROPICAL WEATHER ADVISORY FOR THE WESTERN AND SOUTH PACIFIC OCEANS/140600Z-150600ZAUG2026// REF/A/MSG/JOINT TYPHOON WRNCEN PEARL HARBOR HI/140152ZAUG2026// REF/B/MSG/JOINT TYPHOON WRNCEN PEARL HARBOR HI/131951ZAUG2026// REF/C/MSG/JOINT TYPHOON WRNCEN PEARL HARBOR HI/140552ZAUG2026// NARR/REFS A AND B ARE TROPICAL CYCLONE WARNINGS. REF C IS A TROPICAL CYCLONE FORMATION ALERT CANCELLATION.// RMKS/ 1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA): A. TROPICAL CYCLONE SUMMARY: (1) AT 14AUG26 0000Z, TROPICAL DEPRESSION 16W (NANGKA) WAS LOCATED NEAR 28.5N 153.4E, APPROXIMATELY 260 NM NORTH OF MINAMI TORI SHIMA, AND HAD TRACKED EAST-NORTHEASTWARD AT 09 KNOTS OVER THE PAST SIX HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 30 KNOTS GUSTING TO 40 KNOTS. SEE REF A (WTPN31 PGTW 140300) FOR FURTHER DETAILS. (2) AT 13AUG26 1800Z, TROPICAL DEPRESSION 13W (PEILOU) WAS LOCATED NEAR 33.8N 170.2E, APPROXIMATELY 891 NM NORTH-NORTHEAST OF WAKE ISLAND, AND HAD TRACKED NORTHEASTWARD AT 13 KNOTS OVER THE PAST SIX HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 30 KNOTS GUSTING TO 40 KNOTS. SEE REF B (WTPN32 PGTW 132100) FOR THE FINAL WARNING ON THIS SYSTEM. (3) NO OTHER TROPICAL CYCLONES. B. TROPICAL DISTURBANCE SUMMARY: (1) THE AREA OF CONVECTION (INVEST 93W) PREVIOUSLY LOCATED NEAR 22N 138E IS NOW LOCATED NEAR 22.5N 141.5E, APPROXIMATELY 137 NM SOUTH OF IWO TO. ANIMATED MULTISPECTRAL SATELLITE IMAGERY (MSI) DEPICTS A VERY COMPACT, TIGHTLY WRAPPED LOW-LEVEL CIRCULATION CENTER (LLCC) WITH FLARING CONVECTION REDEVELOPING OVER THE LAST FEW HOURS IN THE VICINITY OF THE LLCC. A 140040Z ASCAT-C PASS REVEALS 15-20 KNOTS WINDS AROUND THE NORTHWESTERN PERIPHERY OF THE CIRCULATION, WITH SOME HIGHER WINDS FURTHER TO THE SOUTH IN THE MONSOONAL SOUTHWESTERLIES. ENVIRONMENTAL ANALYSIS REVEALS FAVORABLE CONDITIONS FOR DEVELOPMENT, WITH LOW VERTICAL WIND SHEAR (10 TO 15KTS), WARM SEA SURFACE TEMPERATURES (29 TO 30C), AND MODERATE POLEWARD OUTFLOW. DETERMINISTIC MODELS DEPICT A CIRCULATION THAT MOVES GENERALLY NORTH-NORTHEAST BUT DOES NOT DEVELOP INTO A TROPICAL CYCLONE. ENSEMBLE MODELS SHOW GOOD DEVELOPMENT BUT SHORT-LIVED DURATION, OF TROPICAL DEPRESSION STRENGTH AND A SIMILAR TRACK TO THE DETERMINISTIC MODELS OVER THE NEXT 24-36 HOURS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 17 TO 22 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1002 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS DOWNGRADED TO MEDIUM. SEE REF C (WTPN21 PGTW 140600) 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.// NNNN
