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 29JAN24 1800Z, TROPICAL CYCLONE 06S (ANGGREK) WAS LOCATED 
NEAR 26.3S 70.8E, APPROXIMATELY 832 NM EAST-SOUTHEAST OF PORT LOUIS, 
MAURITIUS, AND HAD TRACKED SOUTHWARD AT 12 KNOTS OVER THE PAST SIX 
HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 105 KNOTS 
GUSTING TO 130 KNOTS. SEE REF A (WTXS32 PGTW 292100) FOR FURTHER 
DETAILS.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 93S) PREVIOUSLY LOCATED NEAR 
16.0S 64.3E IS NOW LOCATED NEAR 17.6S 64.4E, APPROXIMATELY 136 NM 
NORTH-NORTHEAST OF PORT MATHURIN. ENHANCED INFRARED SATELLITE IMAGERY 
AND A 291216Z SSMIS 91GHZ MICROWAVE SATELLITE IMAGERY DEPICTS AN AREA 
OF FLARING AND SLOWLY CONSOLIDATING CONVECTION AND SHALLOW BANDING 
WRAPPING INTO THE LLCC. UPPER LEVEL ANALYSIS DEPICTS A  MARGINALLY 
FAVORABLE ENVIRONMENT WITH MODERATE TO HIGH (20-25 KNOTS) VERTICAL 
WIND SHEAR, OFFSET BY WARM (29C) SEA SURFACE TEMPERATURES (SST) AND 
GOOD UPPER LEVEL DIVERGENCE. GLOBAL MODELS ARE IN GOOD AGREEMENT THAT 
93S WILL GENERALLY TRACK SOUTHEASTWARD AS IT MOVES OVER FAVORABLE 
CONDITIONS AND INTENSIFIES OVER THE NEXT 24 TO 36 HOURS. MAXIMUM 
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 23 TO 27 KNOTS. MINIMUM SEA 
LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1006 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.//
