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) THE AREA OF CONVECTION (INVEST 93S) PREVIOUSLY LOCATED 
NEAR 21.9S 36.4E IS NOW LOCATED NEAR 21.7S 37.1E, APPROXIMATELY 161 
NM NORTHEAST OF MAXIXE, MOZAMBIQUE. ANIMATED ENHANCED INFRARED 
SATELLITE IMAGERY (EIR), SUPPORTED BY A 162306Z AMSR2 GW1 89GHZ 
MICROWAVE IMAGE, DEPICTS A LARGE AREA OF UNSTRUCTURED, FLARING DEEP 
CONVECTION OFFSET TO THE NORTHWEST ABOVE A LOW LEVEL CIRCULATION 
(LLC), CURRENTLY TRACKING SOUTHEASTWARD BUT TURNING SHARPLY 
SOUTHWARD OVER THE NEXT FEW HOURS. 93S IS IN A MARGINAL ENVIRONMENT 
WITH HIGH (25 TO 30 KNOTS) VERTICAL WIND SHEAR OFFSET BY WARM (29-
30C) SEA SURFACE TEMPERATURES AND NEAR RADIAL UPPER LEVEL OUTFLOW. 
GLOBAL MODELS ARE IN GOOD AGREEMENT THAT 93S WILL TRACK SOUTHWARD AS 
IT INTENSIFIES. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 20 
TO 25 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 REMAINS HIGH. SEE REF A (WTXS21 
PGTW 170300) FOR FURTHER DETAILS.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.      
3. JUSTIFICATION FOR REISSUE: REISSUED TCFA FOR AREA IN PARA 2.B.
