ABIO10 PGTW 062200 MSGID/GENADMIN/JOINT TYPHOON WRNCEN PEARL HARBOR HI// SUBJ/SIGNIFICANT TROPICAL WEATHER ADVISORY FOR THE INDIAN OCEAN REISSUED/062200Z-071800ZAUG2025// REF/A/MSG/JOINT TYPHOON WRNCEN PEARL HARBOR HI/062151ZAUG2025// AMPN/REF A IS A TROPICAL CYCLONE FORMATION ALERT.// RMKS/ 1. NORTH INDIAN OCEAN AREA (MALAY PENINSULA WEST TO COAST OF AFRICA): A. TROPICAL CYCLONE SUMMARY: NONE. B. TROPICAL DISTURBANCE SUMMARY: NONE. C. SUBTROPICAL SYSTEM SUMMARY: NONE. 2. SOUTH INDIAN OCEAN AREA (135E WEST TO COAST OF AFRICA): A. TROPICAL CYCLONE SUMMARY: NONE. B. TROPICAL DISTURBANCE SUMMARY: (1) THE AREA OF CONVECTION (INVEST 91S) PREVIOUSLY LOCATED NEAR 6.2S 62.1E IS NOW LOCATED NEAR 7.3S 62.5E, APPROXIMATELY 595 NM WEST OF DIEGO GARCIA. ANIMATED MULTISPECTRAL SATELLITE IMAGERY (MSI) DEPICTS PERSISTENT DEEP CONVECTION OVER AN OBSCURED LOW-LEVEL CIRCULATION CENTER (LLCC). A 061709Z METOP-C ASCAT IMAGE SHOWS AN ASYMMETRIC WIND FIELD WITH STRONGER (30-35 KTS) WINDS WITHIN THE SOUTHERN SEMICIRCLE. ENVIRONMENTAL ANALYSIS REVEALS FAVORABLE CONDITIONS WITH LOW TO MODERATE EASTERLY VERTICAL WIND SHEAR (15-20 KNOTS), STRONG POLEWARD OUTFLOW ALOFT, AND WARM SEA SURFACE TEMPERATURES (28-29 C). GLOBAL MODELS ARE IN GOOD AGREEMENT THAT INVEST 91S WILL CONTINUE TO TRACK GENERALLY WESTWARD OVER THE NEXT 24 HOURS AND CONTINUE TO DEVELOP. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 28 TO 33 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1004 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS UPGRADED TO HIGH. SEE REF A (WTXS21 PGTW 062200) FOR FURTHER DETAILS. (2) NO OTHER SUSPECT AREAS. C. SUBTROPICAL SYSTEM SUMMARY: NONE. 3. JUSTIFICATION FOR REISSUE: UPGRADED AREA IN PARA 2.B.(1) TO HIGH.// NNNN
