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) THE AREA OF CONVECTION (INVEST 95S) PREVIOUSLY LOCATED NEAR 
13.9S 63.8E IS NOW LOCATED NEAR 15.4S 60.4E, APPROXIMATELY 332 NM NORTH-
NORTHEAST OF MAURITIUS. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY AND 
A 231455Z SSMIS 91GHZ MICROWAVE IMAGE DEPICTS DISORGANIZED BANDING 
WRAPPING INTO A WEAK LOW LEVEL CIRCULATION CENTER (LLCC) WITH FLARING 
CONVECTION IN THE SOUTHERN SEMI-CIRCLE OF THE LLCC. INVEST 95S IS IN A 
FAVORABLE ENVIRONMENT FOR FURTHER DEVELOPMENT WITH GOOD POLEWARD OUTFLOW, 
LOW (10-15 KTS) VERTICAL WIND SHEAR, AND WARM (28-29C) SEA SURFACE 
TEMPERATURES. GLOBAL MODELS ARE IN GOOD AGREEMENT THAT INVEST 95S WILL 
CONTINUE TO TRACK SOUTHWESTWARD WITH STEADY INTENSIFICATION OVER THE NEXT 
24 HOURS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 20 TO 25 
KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1001 MB. THE 
POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN 
THE NEXT 24 HOURS REMAINS MEDIUM.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.//
