TROPICAL CYCLONE 19S (FARAJI), LOCATED APPROXIMATELY 923 NM SOUTHEAST OF DIEGO GARCIA, HAS TRACKED SOUTH-SOUTHEASTWARD AT 04 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED (EIR) SATELLITE IMAGERY SHOWED THE SYSTEM MAINTAINED AN OVERALL SYMMETRICAL CONVECTIVE STRUCTURE AND A RAGGED, ALBEIT WELL-DEFINED, 15-NM EYE. THE INITIAL POSITION IS PLACED WITH HIGH CONFIDENCE BASED ON THE EYE FEATURE IN THE EIR LOOP, ADJUSTED FOR A SLIGHT TILT, THAT LINED UP WELL WITH A MICROWAVE EYE IN THE 101559Z AMSU-B IMAGE. THE INITIAL INTENSITY IS BASED ON THE CONGRUENT AND CLUSTERED AGENCY DVORAK FIXES OF T5.0/90KTS FROM PGTW, FMEE, AND SUPPORTED BY THE OBJECTIVE DVORAK ESTIMATE OF T4.8/86KTS FROM SATCON. UPPER LEVEL ANALYSIS INDICATES LOW (05-10KT) VERTICAL WIND SHEAR (VWS) AND GOOD RADIAL OUTFLOW WITH BIAS ALONG THE POLEWARD SIDE. ALONG-TRACK SST REMAINS WARM AND CONDUCIVE AT 28C. THE CYCLONE WILL CONTINUE TO TRACK ALONG THE WESTERN EDGE OF THE NEAR-EQUATORIAL RIDGE TO THE EAST UP TO TAU 24. AFTERWARD, A BUILDING SUBTROPICAL RIDGE TO THE SOUTH WILL GRADUALLY ASSUME STEERING AND DRIVE THE SYSTEM GENERALLY WESTWARD FOR THE REST OF THE FORECAST. THE FAVORABLE ENVIRONMENT WILL SUSTAIN THE CURRENT INTENSITY UP TO TAU 12; AFTERWARD, AS THE TC TRANSITIONS TO A WESTWARD TRACK, THE RELATIVE VWS IS EXPECTED TO INCREASE TO MODERATE (15-20KTS), OFFSETTING THE OTHERWISE FAVORABLE DYNAMICS, RESULTING IN A GRADUAL WEAKENING. BY TAU 120, TC 19S WILL BE REDUCED TO 35KTS. NUMERICAL MODELS ARE IN OVERALL GOOD AGREEMENT WITH THE ENVELOPE SPREADING TO OVER 270NM BY TAU 120 AND NAVGEM REMAINING THE NOTABLE LEFT OUTLIER. THE JTWC FORECAST TRACK IS PLACED JUST TO THE RIGHT OF THE MODEL CONSENSUS TO OFFSET NAVGEM WITH FAIR CONFIDENCE. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 101800Z IS 40 FEET. NEXT WARNINGS AT 110900Z AND 112100Z.// NNNN
