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 93S) HAS PERSISTED NEAR 
14.1S 59.0E, APPROXIMATELY 378 NM NORTH-NORTHEAST OF MAURITIUS. 
ANIMATED ENHANCED MULTISPECTRAL SATELLITE IMAGERY DEPICTS BROAD 
FLARING CONVECTION OVERHEAD OF A LOW LEVEL CIRCULATION (LLC). A 
200455Z ASCAT B PASS SHOWS WINDS OF UP TO 25 KNOTS IN THE NORTHERN 
PERIPHERY OF THE LLC. ENVIRONMENTAL ANALYSIS DEPICTS FAVORABLE 
CONDITIONS FOR DEVELOPMENT DEFINED BY RADIAL OUTFLOW ALOFT, LOW TO 
MODERATE (10-15KT) VERTICAL WIND SHEAR, AND WARM (29-30C) SEA 
SURFACE TEMPERATURES. GLOBAL MODELS ARE IN GOOD AGREEMENT THAT 93S 
WILL TRACK WESTWARD INTO THE NORTH EASTERN COAST OF MADAGASCAR AS IT 
INTENSIFIES OVER THE NEXT 48-72 HOURS.  MAXIMUM SUSTAINED SURFACE 
WINDS ARE ESTIMATED AT 20 TO 25 KNOTS. MINIMUM SEA LEVEL PRESSURE IS 
ESTIMATED TO BE NEAR 1006 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A 
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS UPGRADED TO 
LOW.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
3. JUSTIFICATION FOR REISSUE: ADDED AREA IN PARA 2.B.(1) AS A LOW.//
