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:
      (1) AT 03FEB22 1200Z, TROPICAL CYCLONE 08S (BATSIRAI) WAS 
LOCATED NEAR 19.2S 54.9E, APPROXIMATELY 81 NM NORTH-NORTHWEST OF LA 
REUNION, AND HAD TRACKED WEST-SOUTHWESTWARD AT 04 KNOTS OVER THE 
PAST SIX HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 
115 KNOTS GUSTING TO 140 KNOTS. SEE REF A (WTXS31 PGTW 031500) FOR 
FURTHER DETAILS.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 90S) PREVIOUSLY LOCATED 
NEAR 18.0S 81.0E IS NOW LOCATED NEAR 17.1S 83.3E, APPROXIMATELY 855 
NM SOUTHEAST OF DIEGO GARCIA. ANIMATED ENHANCED INFRARED SATELLITE 
IMAGERY DEPICTS CONSOLIDATING CONVECTION PARTIALLY OBSCURING A LOW 
LEVEL CIRCULATION. ENVIRONMENTAL ANALYSIS REVEALS FAVORABLE 
CONDITIONS FOR DEVELOPMENT DEFINED BY; ROBUST EQUATORWARD OUTFLOW 
ALOFT, LOW (10-15KT) VERTICAL WIND SHEAR, AND WARM (28-29C) SEA 
SURFACE TEMPERATURES. GLOBAL MODELS ARE IN GOOD AGREEMENT THAT 
INVEST 90S WILL GRADUALLY INTENSIFY ALONG AN EQUATORWARD TRACK 
BEFORE TURNING TO A MORE WEST-SOUTHWESTWARD TRACK AROUND TAU 36.  
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 REMAINS MEDIUM.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.//
