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:
      (1) AT 10SEP25 1800Z, TROPICAL CYCLONE 03S (THREE) WAS LOCATED 
NEAR 10.2S 64.7E, APPROXIMATELY 499 NM WEST-SOUTHWEST OF DIEGO 
GARCIA, AND HAD TRACKED NORTHWESTWARD AT 05 KNOTS OVER THE PAST SIX 
HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 35 KNOTS 
GUSTING TO 45 KNOTS. SEE REF A (WTXS31 PGTW 102100) FOR FURTHER 
DETAILS.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 93S) PREVIOUSLY LOCATED NEAR 
6.2S 95.5E IS NOW LOCATED NEAR 7.0S 95.0E, APPROXIMATELY 333 NM 
NORTH-NORTHWEST OF COCOS ISLANDS. ANIMATED MULTISPECTRAL SATELLITE 
IMAGERY (MSI) AND A 110400Z MWR 89GHZ MICROWAVE IMAGE DEPICT AN 
OBSCURED, LOW LEVEL CIRCULATION (LLC) WITH PERSISTENT, DISORGANIZED 
CONVECTION OVER THE CENTER. ENVIRONMENTAL ANALYSIS REVEALS A MARGINAL 
ENVIRONMENT FOR DEVELOPMENT WITH HIGH VERTICAL WIND SHEAR (VWS) OF 
40-50 KNOTS, GOOD POLEWARD UPPER-LEVEL OUTFLOW, AND WARM SEA SURFACE 
TEMPERATURES (SST) OF 28-29 C. DETERMINISTIC AND ENSEMBLE MODELS ARE 
IN DISAGREEMENT ON THE INTENSITY OF THE SYSTEM BUT ARE IN GOOD 
AGREEMENT ON A GENERALLY SOUTHWESTWARD TRACK. MAXIMUM SUSTAINED 
SURFACE WINDS ARE ESTIMATED AT 30 TO 35 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 REMAINS HIGH. SEE REF B (WTXS21 PGTW 110800) FOR FURTHER 
DETAILS.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
3. JUSTIFICATION FOR REISSUE: REISSUED TROPICAL CYCLONE FORMATION 
ALERT FOR INVEST 93S.//
