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 21JAN24 1800Z, TROPICAL CYCLONE 06S (ANGGREK) WAS 
LOCATED NEAR 12.3S 91.8E, APPROXIMATELY 299 NM WEST OF COCOS ISLANDS, 
AND HAD TRACKED WEST-SOUTHWESTWARD AT 02 KNOTS OVER THE PAST SIX 
HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 50 KNOTS 
GUSTING TO 65 KNOTS. SEE REF A (WTXS32 PGTW 212100) FOR FURTHER 
DETAILS.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) AN AREA OF CONVECTION (INVEST 92S) HAS PERSISTED NEAR 17.4S 
64.4E, APPROXIMATELY 425 NM EAST-NORTHEAST OF MAURITIUS. ANIMATED 
ENHANCED INFRARED (EIR) SATELLITE IMAGERY AND A 212057Z AMSR2 DERIVED 
WINDSPEED IMAGE DEPICT A BROAD AREA OF TURNING ALONG A TROUGHING AREA 
OF WEST TO EAST ORIENTATION. MAXIMUM WIND SPEEDS (23-27KTS) FILL THE 
MAJORITY OF THE NORTHERN PERIPHERY, WITH LIGHTER (10-15KTS) WINDS TO 
THE SOUTH. THE POSITION IS BASED ON THE CENTROID OF THE BROAD 
CIRCULATION. UPPER-LEVEL ANALYSIS INDICATES 92S IS IN A FAVORABLE 
ENVIRONMENT FOR DEVELOPMENT WITH MODERATE TO HIGH (15-25 KNOT) VWS 
OFFSET BY GOOD DIVERGENCE ALOFT AND WARM (29-30C) SEA SURFACE 
TEMPERATURES. GLOBAL MODELS ARE IN GOOD AGREEMENT THAT 92S WILL 
CONTINUE TO TRACK GENERALLY SOUTHWESTWARD TO SOUTH-SOUTHWESTWARD AND, 
THOUGH OVERALL CONDITIONS ARE FAVORABLE, THE LACK OF A DISTINCT, 
CONSOLIDATED LLCC AT THIS TIME WILL SERVE TO LIMIT THE POTENTIAL 
DEVELOPMENT. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 23 TO 
27 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 LOW.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
3. JUSTIFICATION FOR REISSUE: ADDED LOW AREA IN PARA. 1.B.(1).//
