   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 9.3S 89.9E HAS DISSIPATED AND IS NO LONGER SUSPECT FOR THE 
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE IN THE NEXT 24 HOURS. 
      (2) THE AREA OF CONVECTION (INVEST 94S) PREVIOUSLY LOCATED 
NEAR 16.7S 125.8E HAS DISSIPATED AND IS NO LONGER SUSPECT FOR THE 
DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE IN THE NEXT 24 HOURS. 
      (3) THE AREA OF CONVECTION (INVEST 95S) PREVIOUSLY LOCATED 
NEAR 10.9S 67.1E IS NOW LOCATED NEAR 12.0S 63.8E, APPROXIMATELY 601 
NM NORTHEAST OF MAURITIUS. ANIMATED ENHANCED INFRARED SATELLITE 
IMAGERY AND A 201218Z SSMIS 91GHZ SATELLITE IMAGE DEPICT A BROAD 
AREA OF TURNING WITH FLARING CONVECTION SCATTERED THROUGHOUT. INVEST 
95S IS IN A MARGINALLY FAVORABLE ENVIRONMENT FOR DEVELOPMENT WITH 
WARM (29-30C) SEA SURFACE TEMPERATURES, MODERATE OUTFLOW ALOFT, AND 
LOW TO MODERATE (15-20KTS) VERTICAL WIND SHEAR. GLOBAL MODELS ARE IN 
GENERAL AGREEMENT THAT INVEST 95S WILL CONTINUE TO CONSOLIDATE AS IT 
TRACKS SOUTHWESTWARD OVER THE NEXT SEVERAL DAYS. MAXIMUM SUSTAINED 
SURFACE WINDS ARE ESTIMATED AT 15 TO 20 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 REMAINS LOW.
      (4) NO OTHER SUSPECT AREAS.
