22S(MARIAN). WARNING 2 ISSUED AT 26/15UTC. UPPER LEVEL ANALYSIS INDICATES LOW TO MODERATE (10-15KT) VERTICAL WIND SHEAR AND GOOD RADIAL OUTFLOW. ADDITIONALLY, ALONG-TRACK SEA SURFACE TEMPERATURES ARE CONDUCIVE AT 28-29C. TC 22S WILL TRACK MORE WEST-SOUTHWESTWARD TO SOUTHWESTWARD ALONG THE NORTHWESTERN PERIPHERY OF THE DEEP-LAYERED SUBTROPICAL RIDGE (STR) TO THE SOUTHEAST. AFTER 48H, THE CYCLONE WILL SLOW DOWN AS IT ROUNDS THE WESTERN EDGE OF THE STR, AND AFTER 96H, WILL RE-ACCELERATE SOUTHEASTWARD ON THE POLEWARD SIDE OF THE STR. THE FAVORABLE ENVIRONMENT WILL PROMOTE A GRADUAL INTENSIFICATION TO A PEAK OF 85KTS/US CATEGORY 2 BY 72H. AFTERWARD, INCREASING WIND SHEAR AS THE SYSTEM MAKES THE TURN INTO THE PREVAILING WESTERLIES WILL GRADUALLY ERODE THE SYSTEM DOWN TO 65KNOTS/US CATEGORY 1 BY 120H.
22S(MARIAN). NUMERICAL MODELS ARE IN TIGHT AGREEMENT UP 48H, LENDING HIGH CONFIDENCE TO THE EARLY TO MID PORTION OF THE FORECAST; AFTERWARD, THERE IS SIGNIFICANT DIFFERENCES IN THE MODEL TRAJECTORIES AND ALONG- TRACK SPEEDS AS THE VORTEX NAVIGATES THE TURN AROUND THE STR AXIS, LENDING LOW CONFIDENCE TO THE LATTER PORTION OF THE JTWC TRACK FORECAST.
