19S(FARAJI). WARNING 15 ISSUED AT 12/09UTC.TC 19S(FARAJI) IS TRACKING ALONG THE NORTHWESTERN PERIPHERY OF A  SUBTROPICAL RIDGE (STR) POSITIONED TO THE SOUTHEAST AND THROUGH A MARGINALLY UNFAVORABLE ENVIRONMENT  CHARACTERIZED BY WARM (27-28 CELSIUS) SEA SURFACE TEMPERATURES (SST) AND ROBUST POLEWARD OUTFLOW ALOFT OFFSET BY HIGH (20-25 KTS) VERTICAL WIND SHEAR AND  CONVERGENT UPPER LEVEL FLOW ALONG THE NORTHWESTERN  PERIPHERY OF THE SYSTEM. TC FARAJI WILL CONTINUE TO  WEAKEN TO 45 KNOTS THROUGH 36H AS IT TRACKS WEST- SOUTHWESTWARD UNDER THE STEERING INFLUENCE OF THE STR. THEREAFTER THE PRIMARY STEERING MECHANISM WILL SHIFT  TO A DEEP LAYER STR POSITIONED TO THE SOUTH THAT WILL DRIVE THE SYSTEM GENERALLY WEST-NORTHWESTWARD THROUGH THE REMAINDER OF THE FORECAST PERIOD.A BRIEF PERIOD OF INTENSIFICATION IS FORECAST AFTER 96H AS THE UPPER LEVEL OUTFLOW IMPROVES AND WIND SHEAR  DECREASES, LEADING TO AN INTENSITY OF 45 KNOTS BY 120H.

19S(FARAJI). NUMERICAL MODEL TRACK GUIDANCE IS IN OVERALL GOOD AGREEMENT WITH THE EXCEPTION OF NAVGEM THAT CONTINUES TO PROVIDE A SIGNIFICANT POLEWARD BIAS. WHEN REMOVING THE NAVGEM TRACK FROM THE MODEL CONSENSUS, THE MAXIMUM SPREAD IN ACROSS TRACK SOLUTIONS IS 650 KM AT 120H.  THIS LOW SPREAD IN TRACK GUIDANCE LENDS OVERALL HIGH CONFIDENCE IN THE JTWC FORECAST TRACK WHICH IS PLACED JUST RIGHT OF THE MULTI-MODEL CONSENSUS TO OFFSET THE POLEWARD BIAS FROM THE NAVGEM SOLUTION.
