19S(FARAJI). WARNING 13 ISSUED AT 11/09UTC.TC FARAJI IS TRACKING ALONG THE NORTHWESTERN PERIPHERY OF A BUILDING SUBTROPICAL RIDGE (STR) POSITIONED TO THE SOUTHWEST AND THROUGH A MARGINAL ENVIRONMENT CHARACTERIZED BY WARM (27-28 CELSIUS) SEA SURFACE TEMPERATURES AND ROBUST POLEWARD OUTFLOW OFFSET BY MODERATE (15-20 KTS) VERTICAL WIND SHEAR AND CONVERGENT FLOW ALONG THE NORTHWESTERN PERIPHERY OF THE SYSTEM. AS THE STEERING STR CONTINUES TO BUILD IT WILL REPOSITION FARTHER WEST AND BEGIN TO DRIVE TC FARAJI GENERALLY WESTWARD AFTER 36H. MODERATE WIND SHEAR COUPLED WITH PERIODS OF CONVERGENT FLOW ALOFT WILL WEAKEN THE SYSTEM TO 45 KNOTS BY 72H. THEREAFTER, THE STEERING STR WILL REPOSITION AND BEGIN TO STEER THE SYSTEM WEST-NORTHWESTWARD. LOW (5-10 KTS) WIND SHEAR AND CONTINUED WARM (28-39 CELSIUS) SEAS AFTER 72H WILL LEAD TO GRADUAL INTENSIFICATION TO 55 KNOTS BY 120H.
19S(FARAJI). NUMERICAL MODELS ARE IN FAIR AGREEMENT, ALTHOUGH THE NAVGEM MODEL PROVIDES A FAR LEFT OF TRACK (POLEWARD) SOLUTION. ADDITIONALLY, THE DYNAMIC NATURE OF THE STEERING SUBTROPICAL RIDGE REPOSITIONING RESULTS IN A SIGNIFICANT AMOUNT OF ALONG TRACK SPREAD IN MODEL SOLUTIONS. THIS ALONG TRACK SPREAD IN MODEL SOLUTIONS, COUPLED WITH A 740 KM ACROSS TRACK SPREAD AT 120H, LENDS OVERALL FAIR CONFIDENCE IN THE JTWC FORECAST TRACK WHICH IS PLACED JUST RIGHT OF THE MULTI-MODEL CONSENSUS TO OFFSET THE APPARENT NAVGEM BIAS.
