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 30JAN24 0600Z, TROPICAL CYCLONE 06S (ANGGREK) WAS LOCATED 
NEAR 29.1S 72.8E, APPROXIMATELY 1002 NM SOUTHEAST OF PORT LOUIS, 
MAURITIUS, AND HAS TRACKED SOUTHEASTWARD AT 15 KNOTS OVER THE PAST SIX 
HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 100 KNOTS 
GUSTING TO 125 KNOTS. SEE REF A (WTXS32 PGTW 300900) FOR FURTHER 
DETAILS.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 93S) PREVIOUSLY LOCATED NEAR 
18.8S 64.5E IS NOW LOCATED NEAR 18.6S 64.8E, APPROXIMATELY 420 NM 
EAST-NORTHEAST OF MAURITIUS. ENHANCED INFRARED IMAGERY AND A 301428Z 
SSMIS 91GHZ MICROWAVE SATELLITE IMAGERY DEPICTS CONSOLIDATING LLCC AND 
CURVED DEEP CONVECTIVE BANDING OVER THE CIRCULATION CENTER. UPPER 
LEVEL ANALYSIS DEPICTS A FAVORABLE ENVIRONMENT FOR CONTINUED 
DEVELOPMENT WITH LOW (5-10 KNOTS) VERTICAL WIND SHEAR, WARM (29C) SEA 
SURFACE TEMPERATURES (SST), AND FAVORABLE POLEWARD DIVERGENCE. 
MULTIPLE GLOBAL MODELS ARE IN GOOD AGREEMENT THAT 93S WILL TRACK 
SOUTH-SOUTHEASTWARD OVER THE NEXT 24-36 HOURS. MAXIMUM SUSTAINED 
SURFACE WINDS ARE ESTIMATED AT 28 TO 33 KNOTS. MINIMUM SEA LEVEL 
PRESSURE IS ESTIMATED TO BE NEAR 1003 MB. THE POTENTIAL FOR THE 
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS 
REMAINS HIGH. SEE REF B (WTXS21 PGTW 301330) FOR FURTHER DETAILS.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.//
