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 03FEB26 1200Z, TROPICAL CYCLONE 19S (FYTIA) WAS LOCATED 
NEAR 23.8S 54.5E, APPROXIMATELY 203 NM SOUTH-SOUTHWEST OF ST DENIS, AND 
HAD TRACKED SOUTHEASTWARD AT 06 KNOTS OVER THE PAST SIX HOURS. MAXIMUM 
SUSTAINED SURFACE WINDS WERE ESTIMATED AT 50 KNOTS GUSTING TO 65 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 
11.S 64.0E IS NOW LOCATED NEAR 11.3S 63.9E, APPROXIMATELY 562 NM WEST-
SOUTHWEST OF DIEGO GARCIA. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY 
(EIR) REVEALS A PARTIALLY EXPOSED LOW LEVEL CIRCULATION CENTER (LLCC) 
WITH DISORGANIZED FLARING CONVECTION. ENVIRONMENTAL ANALYSIS REVEALS 
FAVORABLE CONDITIONS FOR DEVELOPMENT WITH LOW TO MODERATE VERTICAL WIND 
SHEAR (15-20 KNOTS), GOOD EQUATORWARD UPPER-LEVEL OUTFLOW, AND WARM (28-
29 C) SEA SURFACE TEMPERATURES. GLOBAL MODELS ARE IN GOOD AGREEMENT THAT 
INVEST 90S WILL TRACK SLOWLY SOUTHWARD AND STEADILY DEVELOP OVER THE 
NEXT 48 HOURS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 18 TO 23 
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.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.//
