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 
11.4S 64.9E IS NOW LOCATED NEAR 11.6S 64.3E, APPROXIMATELY 545 NM WEST-
SOUTHWEST OF DIEGO GARCIA. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY 
(EIR) REVEALS AN EXPOSED LOW-LEVEL CIRCULATION CENTER THAT IS CONTINUING 
TO CONSOLIDATE. CONVECTION HAS REMAINED CONFINED TO THE NORTHWESTERN 
QUADRANT OF THE SYSTEM. ENVIRONMENTAL ANALYSIS REVEALS FAVORABLE 
CONDITIONS FOR DEVELOPMENT WITH MODERATE VERTICAL WIND SHEAR (15-20 
KNOTS), GOOD UPPER-LEVEL EQUATORWARD OUTFLOW, AND WARM (28-29 C) SEA 
SURFACE TEMPERATURES. GLOBAL MODELS AGREE ON A SLOW SOUTHWARD TRACK AND 
STEADY DEVELOPMENT 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 1008 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A 
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS UPGRADED TO 
MEDIUM.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
3. JUSTIFICATION FOR REISSUE: UPGRADED AREA IN PARA 2.B.(1) TO MEDIUM//
