ANIMATED INFRARED SATELLITE IMAGERY REVEALS DEEP CONVECTION WHICH HAS CONSOLIDATED OVER THE LOW LEVEL CIRCULATION CENTER (LLCC) AND IS WRAPPING INTO THE CIRCULATION CENTER. INITIAL POSITION IS BASED ON ANIMATED INFRARED IMAGERY AND IS SUPPORTED BY A 142303Z SSMI 37 GHZ MICROWAVE IMAGE SHOWING DEEP CONVECTIVE BANDING WRAPPING FROM THE SOUTH AND INTO THE EQUATORWARD SIDE OF THE CIRCULATION CENTER. THE INITIAL INTENSITY OF 35 KNOTS IS HEDGED ON THE UPPER END OF MULTI-AGENCY DVORAK CURRENT INTENSITY ESTIMATES RANGING FROM T2.0 TO T2.5 (30 TO 35 KNOTS). UPPER LEVEL ANALYSIS REVEALS THE SYSTEM HAS RADIAL OUTFLOW WITH A POINT SOURCE ALOFT TO THE EAST AND GOOD DIVERGENCE DIRECTLY OVERHEAD. ENVIRONMENTAL ANALYSIS SHOWS THE SYSTEM IS IN AN AREA OF MODERATE TO HIGH (20-25 KNOTS) VERTICAL WIND SHEAR (VWS) AND IS TRACKING THROUGH AN AREA OF WARM (29-30 CELSIUS) SEA SURFACE TEMPERATURES. TC 14S IS FORECAST TO STEADILY INTENSIFY AS IT TRACKS TO THE SOUTHWEST OVER THE NEXT 36 HOURS. THE SYSTEM WILL PEAK AT 60 KNOTS PRIOR TO MAKING LANDFALL OVER NORTHEASTERN MADAGASCAR. AFTER LANDFALL, THE SYSTEM WILL WEAKEN DUE TO THE FRICTIONAL EFFECTS OF LAND INTERACTION. ALSO AFTER LANDFALL, THE SYSTEM WILL ROUND THE AXIS OF THE SUBTROPICAL STEERING RIDGE LOCATED TO THE EAST AND TURN TO THE SOUTHWEST, EXITING BACK INTO THE SOUTHERN INDIAN OCEAN SHORTLY AFTER TAU 72. ONCE OUT OVER WATER, TC 14S WILL GRADUALLY STRENGTHEN THROUGH TAU 120. AVAILABLE DYNAMIC MODEL GUIDANCE IS IN GENERAL AGREEMENT ON TRACK DIRECTION WITH LARGE VARIATIONS IN THE TIMING AND SHARPNESS OF THE TURN TO THE SOUTHWEST. DUE TO THE LARGE VARIATIONS IN THE MODEL GUIDANCE THERE IS OVERALL LOW CONFIDENCE IN THE JTWC FORECAST TRACK. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 150000Z IS 16 FEET. NEXT WARNINGS AT 150900Z, 151500Z, 152100Z AND 160300Z.THIS CANCELS AND SUPERSEDES REF A (WTXS21 PGTW 140300).//NNNN
