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 HAD 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 
17.6S 64.4E IS NOW LOCATED NEAR 18.8S 64.5E, APPROXIMATELY 81 NM 
NORTHEAST OF PORT MATHURIN. ANIMATED MULTISPECTRAL SATELLITE IMAGERY 
(MSI) DEPICTS A QUICKLY CONSOLIDATING LOW LEVEL CIRCULATION CENTER (LLCC) 
WITH DEEP CONVECTION DISPLACED SLIGHTLY WEST OF THE LLCC. A 300536Z ASCAT 
METOP-C SCATTEROMETER PARTIAL PASS SHOWS AN OVAL SHAPED LLCC WITH 
STRONGER WINDS NOW WRAPPING AROUND THE SOUTHERN PERIPHERY OF CIRCULATION. 
UPPER-LEVEL ANALYSIS REVEALS A FAVORABLE ENVIRONMENT WITH LOW TO MODERATE 
VWS (15 TO 20 KNOTS ), SEA SURFACE TEMPERATURES (SST) OF 28-29C, A STRONG 
850MB VORTICITY SIGNATURE, AND GOOD POLEWARD OUTFLOW ALOFT. GLOBAL MODELS 
ARE IN AGREEMENT THAT 93S WILL CONTINUE TRACKING SOUTHEASTWARD WITH 
CONTINUOUS DEVELOPMENT AND INTENSIFICATION OVER THE NEXT 12-24 HOURS. 
SOUTHEASTWARD AS IT MOVES OVER FAVORABLE CONDITIONS AND INTENSIFIES OVER 
THE NEXT 24 TO 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 IS UPGRADED TO HIGH. SEE REF B (WTXS21 PGTW 
301330) FOR FURTHER DETAILS.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
3. JUSTIFICATION FOR REISSUE: UPGRADED AREA IN PARA 2.B. (1) TO HIGH.//
