ABPW10 PGTW 010600 MSGID/GENADMIN/JOINT TYPHOON WRNCEN PEARL HARBOR HI// SUBJ/SIGNIFICANT TROPICAL WEATHER ADVISORY FOR THE WESTERN AND SOUTH PACIFIC OCEANS/010600Z-020600ZAUG2025// REF/A/MSG/JOINT TYPHOON WRNCEN PEARL HARBOR HI/010151ZAUG2025// AMPN/REF A IS A TROPICAL CYCLONE WARNING.// RMKS/ 1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA): A. TROPICAL CYCLONE SUMMARY: (1) AT 01AUG25 0000Z, TROPICAL STORM 12W (KROSA) WAS LOCATED NEAR 32.6N 141.7E, APPROXIMATELY 190 NM SOUTH-SOUTHEAST OF YOKOSUKA, JAPAN, AND HAD TRACKED NORTH-NORTHWESTWARD AT 10 KNOTS OVER THE PAST SIX HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 55 KNOTS GUSTING TO 70 KNOTS. SEE REF A (WTPN31 PGTW 010300) FOR FURTHER DETAILS. (2) NO OTHER TROPICAL CYCLONES. B. TROPICAL DISTURBANCE SUMMARY: (1) THE AREA OF CONVECTION (INVEST 93W) PREVIOUSLY LOCATED NEAR 25.9N 131.6E IS NOW LOCATED NEAR 25.6N 132.7E, APPROXIMATELY 82 NM EAST OF MINAMI DAITO JIMA. ANIMATED MULTISPECTRAL IMAGERY (MSI) DEPICTS AN ELONGATED AREA OF FLARING CONVECTION. A PARTIAL 010502Z ASCAT-B PASS REVEALS AN ASYMMETRIC WEAK WIND FIELD OF 15-20 KNOT WINDS ALONG THE SOUTHERN PERIPHERY DUE TO THE ENHANCED MONSOONAL FLOW. ENVIRONMENTAL ANALYSIS REVEALS A MARGINAL CONDITIONS FOR DEVELOPMENT WITH LOW TO MODERATE VERTICAL WIND SHEAR, MODERATE UPPER-LEVEL DIVERGENCE AND POLEWARD OUTFLOW, AND WARM (28- 29C) SEA SURFACE TEMPERATURES. GLOBAL MODELS VARY WHETHER OR NOT 93W WILL DEVELOP INTO A TROPICAL CYCLONE, BUT IF IT DOES, THE DEVELOPMENT WILL BE SLOW AS IT TRACKS NORTHEASTWARD OVER THE NEXT 24-36 HOURS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 13 TO 18 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 999 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS REMAINS LOW. (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
