JTWC warning
---------------------------
TROPICAL CYCLONE (TC) 05B (FIVE), LOCATED APPROXIMATELY 565 NM EAST-SOUTHEAST OF CHENNAI, INDIA, HAS TRACKED WESTWARD AT 11 KNOTS OVER THE PAST SIX HOURS. ANIMATED INFRARED SATELLITE IMAGERY DEPICTS IMPROVED DEEP CONVECTIVE BANDING AND OVERALL CONSOLIDATION OVER THE PAST 12 HOURS. A 041520Z METOP-A IMAGE AS WELL AS AN EARLIER 041344Z SSMIS IMAGE DEPICTED A MORE DEFINED LOW-LEVEL CIRCULATION CENTER (LLCC) WITH MULTIPLE CONVECTIVE BANDS WRAPPING INTO THE CENTER. THE SSMIS WIND PRODUCT ALSO SUPPORTED 35 KNOT WINDS WITHIN THE CONVECTIVE BANDING. ANIMATED WATER VAPOR IMAGERY INDICATES IMPROVING POLEWARD OUTFLOW AND GOOD OVERALL OUTFLOW EXCEPT FOR THE EAST QUADRANT DUE TO MODERATE EASTERLY VERTICAL WIND SHEAR (VWS). THE CURRENT INTENSITY IS BASED ON DVORAK ESTIMATES OF 35 KNOTS FROM PGTW AND KNES, AND THE SSMIS WIND DATA. TC 05B IS TRACKING WESTWARD ALONG THE SOUTHERN PERIPHERY OF THE LOW- TO MID-LEVEL SUBTROPICAL RIDGE AND IS FORECAST TO CONTINUE TRACKING WESTWARD TO WEST-NORTHWESTWARD THROUGH THE FORECAST PERIOD. AVAILABLE MODEL GUIDANCE IS IN TIGHT AGREEMENT, THEREFORE, THIS FORECAST IS POSITIONED CLOSE TO THE MODEL CONSENSUS. TC 05B IS FORECAST TO INTENSIFY AT A SLOW RATE (TO 45 KNOTS) IN THE NEXT 24 HOURS DUE TO THE VWS, BUT IS EXPECTED TO INTENSIFY AT A FASTER RATE AFTER TAU 24 AS VWS DECREASES. THE SYSTEM SHOULD REACH A PEAK INTENSITY NEAR 65 KNOTS PRIOR TO LANDFALL, AND IS EXPECTED TO DISSIPATE OVER LAND BY TAU 96.
