06/0830UTC. JTWC IS ISSUING 12HOURLY WARNINGS ON 19S(FARAJI). 3HOURLY SATELLITE BULLETINS ARE PROVIDED FOR 19S AND 18S.

19S(FARAJI). WARNING 3 ISSUED AT 06/09UTC. FARAJI IS TRACKING THROUGH A HIGHLY FAVORABLE ENVIRONMENT WITH WARM (29-30 CELSIUS) SEA SURFACE TEMPERATURES (SST), ROBUST EQUATORWARD AND MODERATE POLEWARD OUTFLOW ALOFT, AND LOW (5-10 KTS) VERTICAL WIND SHEAR (VWS).THE SYSTEM IS CURRENTLY IN A COMPLEX, ALBEIT WEAK, STEERING ENVIRONMENT THAT HAS LED TO A RELATIVELY SLOW STORM MOTION OVER THE PAST 12 HOURS. THIS SLOW SYSTEM MOTION, COUPLED WITH HIGHLY FAVORABLE ENVIRONMENTAL CONDITIONS, WILL LEAD TO RAPID INTENSIFICATION IN THE NEAR TERM TO 90 KNOTS/US CATEGORY 2 BY 24H. DURING THIS TIME THE STORM MOTION IS FORECAST TO REMAIN RELATIVELY SLOW AS THE SYSTEM DRIFTS POLEWARD ALONG THE PERIPHERY OF A WEAK SUBTROPICAL RIDGE (STR) POSITIONED TO THE SOUTH- EAST. AFTER 12H, TC FARAJI WILL BEGIN TO TRACK EASTWARD ALONG THE SOUTHERN PERIPHERY OF A NEAR EQUATORIAL RIDGE (NER) POSITIONED TO THE NORTH AS THE INITIAL STEERING STR WEAKENS. CONTINUED FAVORABLE ENVIRONMENTAL CONDITIONS WILL LEAD TO FURTHER INTENSIFICATION THROUGH 72H AT WHICH TIME THE SYSTEM WILL REACH A PEAK INTENSITY OF 110 KNOTS/US CATEGORY 3. THEREAFTER, A BUILDING STR POSITIONED TO THE EAST WILL OVERTAKE STEERING AND BEGIN TO DRIVE TC FARAJI SOUTHEASTWARD. DURING THIS TIME, MODERATE (15-25 KTS) WIND SHEAR WILL LEAD TO A GRADUAL WEAKENING TO 90 KNOTS BY 120H.

NUMERICAL MODEL GUIDANCE IS IN OVERALL FAIR AGREEMENT. MODEL SOLUTIONS HAVE CONVERGED ON A GENERALLY EASTWARD STORM MOTION AFTER 24/36H, HOWEVER THE TIMING OF THIS CHANGE IN TRACK DIRECTION IS COMPLICATED BY THE OVERALL COMPLEX AND DYNAMIC STEERING ENVIRONMENT. THE JTWC FORECAST TRACK IS HEDGED SLIGHTLY EQUATORWARD OF THE MULTI-MODEL CONSENSUS TO OFFSET THE CONTRIBUTION FROM THE NAVGEM SOLUTION WHICH LIES 185KM SOUTH OF THE CONSENSUS TRACK AT 36H. OVERALL, MODEL GUIDANCE LENDS OVERALL FAIR CONFIDENCE IN THE JTWC FORECAST TRACK.

INVEST 91P. NUMERICAL MODELS ARE IN FAIR AGREEMENT THAT 91P WILL TRACK SOUTHWARD OVER THE NEXT 24 HOURS AND ENTER OVER NORTHERN AUSTRALIA, RESULTING IN A LOW LIKELIHOOD OF FURTHER DEVELOPMENT.
