/REISSUED/232300Z-241800ZFEB2021//
RMKS/
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: NONE.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) AN AREA OF CONVECTION (INVEST 98S) HAS PERSISTED NEAR 
13.7S 116.3E, APPROXIMATELY 526 NM NORTH-NORTHEAST OF LEARMONTH, 
AUSTRALIA. ANIMATED ENHANCED INFRARED IMAGERY AND A 231900Z GMI 
89GHZ MICROWAVE IMAGE DEPICT A CONSOLIDATING LOW LEVEL CIRCULATION 
CENTER WITH PERSISTENT DEEP CONVECTION. RADIAL OUTFLOW, LOW VERTICAL 
WIND SHEAR (10-15KTS) AND WARM SEA SURFACE TEMPERATURES (29-30C) 
CREATE FAVORABLE CONDITIONS FOR FURTHER DEVELOPMENT. GLOBAL MODELS 
INDICATE INVEST 98S WILL TRACK WESTWARD AND INTENSIFY QUICKLY OVER 
THE NEXT 36-48 HOURS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED 
AT 20 TO 25 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE 
NEAR 1002 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT 
TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS MEDIUM.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
3. JUSTIFICATION FOR REISSUE: ADDED MEDIUM AREA IN PARA 2.B.(1).//
