SUBJ/SIGNIFICANT TROPICAL WEATHER ADVISORY FOR THE INDIAN OCEAN 
REISSUED/200200Z-201800ZFEB2025//
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 99S) PREVIOUSLY LOCATED NEAR 
11.4S 127.4E IS NOW LOCATED NEAR 13.3S 121.2E, APPROXIMATELY 285 NM 
NORTH-NORTHEAST OF ROWLEY SHOALS ATOLL. ANIMATED MULTISPECTRAL SATELLITE 
IMAGERY (MSI) DEPICTS A SLOWLY CONSOLIDATING LOW-LEVEL CIRCULATION 
(LLC) AS LOW-LEVEL CLOUD LINES HAVE STARTED TO WRAP BENEATH A 
SUPPORTIVE CONVECTIVE STRUCTURE NEAR THE ASSESSED CENTER. THE 
ENVIRONMENT IS FAVORABLE FOR DEVELOPMENT WITH LOW VERTICAL WIND SHEAR 
(VWS) OF 10-15 KNOTS, MODERATE EQUATORWARD UPPER-LEVEL OUTFLOW, AND 
WARM SEA SURFACE TEMPERATURES (SST) OF 29-30 C. DETERMINISTIC AND 
ENSEMBLES ARE IN AGREEMENT THAT INVEST 99S WILL CONTINUE TO TRACK 
SOUTHWESTWARD TOWARD ROWLEY SHOALS ATOLL AS IT SLOWLY INTENSIFIES OVER 
THE NEXT 24 TO 48 HOURS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 
23 TO 28 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 UPGRADED TO MEDIUM.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
3. JUSTIFICATION FOR REISSUE: UPGRADED AREA IN PARA 2.B.(1) TO 
MEDIUM.//
