JTWC HAVE ISSUED WARNING 28/FINAL ON 16W AT 17/09UTC. THE SYSTEM IS DOWN-GRADED TO MEDIUM WITH MODERATE CHANCES OF REGENERATION. 3HOURLY SATELLITE BULLETINS ARE STILL ISSUED ON IT.

TD 16W. WARNING 28/FINAL ISSUED AT 17/09UTC. TROPICAL DEPRESSION 16W (SIXTEEN), LOCATED APPROXIMATELY 110 KM WEST-SOUTHWEST OF ANDERSEN AFB, HAS TRACKED WESTWARD AT 21 KM/H OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY (MSI) DEPICTS SPIRAL BANDS OF WEAK, UPPER LEVEL CONVECTION THAT WRAP INTO AN OBSCURED LOW LEVEL CIRCULATION CENTER. COMPOSITE RADAR IMAGERY AND A 170344UTC 165 GHZ IMAGE DEPICT SHALLOW CONVECTION SURROUNDING THE LOW LEVEL CENTER WITH POCKETS OF DEEPER, ALBEIT DISORGANIZED, CONVECTION TO THE EAST AND NORTHEAST. THE COMBINATION OF SATELLITE, RADAR AND MICROWAVE IMAGERY LEND ONLY MEDIUM CONFIDENCE IN THE INITIAL POSITION DUE TO THE BROAD NATURE OF THE LOW LEVEL CIRCULATION. THE INITIAL INTENSITY OF 20 KNOTS IS PLACED WITH MEDIUM CONFIDENCE BASED ON THE OVERALL LACK OF ORGANIZED CONVECTIVE STRUCTURE. THE OVERALL ENVIRONMENT IS MARGINAL WITH VERY WARM SST VALUES (31-32 CELSIUS) OFFSET BY MODERATE TO HIGH VERTICAL WIND SHEAR (20-30 KTS). ADDITIONALLY, NORTHERLY UPPER LEVEL WINDS FROM RIDGING TO THE NORTH IS FURTHER HINDERING DEVELOPMENT. OVER THE NEXT 24 HOURS TD 16W WILL CONTINUE TO TRACK GENERALLY WESTWARD TO WEST-NORTHWESTWARD UNDER THE STEERING INFLUENCE OF THE SUBTROPICAL RIDGE POSITIONED TO THE NORTH AND STRUGGLE TO CONSOLIDATE DUE TO THE CONTINUED MARGINAL ENVIRONMENT.THIS IS THE FINAL WARNING ON THIS SYSTEM BY THE JOINT TYPHOON WRNCEN PEARL HARBOR HI. THE SYSTEM WILL BE CLOSELY MONITORED FOR SIGNS OF REGENERATION.

REMNANTS OF TD 16W.

TD 16W. NUMERICAL MODEL TRACK GUIDANCE IS IN TIGHT AGREEMENT, AND LENDS OVERALL HIGH CONFIDENCE IN THE FORECAST TRACK, HOWEVER THE INTENSITY FORECAST IS PLACED WITH LOW CONFIDENCE DUE TO A HIGH DEGREE OF SPREAD IN THE MODEL INTENSITY GUIDANCE. SPECIFICALLY, THE HWRF AND COAMPS MESOSCALE MODELS DEPICT SYSTEM INTENSIFICATION BEYOND 25 KNOTS BETWEEN 24H AND 48H, HOWEVER GLOBAL MODELS DO NOT DEPICT THIS INTENSIFICATION SCENARIO. THIS REFLECTS THE CURRENT COMPLEX AND UNFAVORABLE THERMODYNAMIC ENVIRONMENT THAT, IN ADDITION TO THE DYNAMIC ENVIRONMENT, HAS THE POTENTIAL TO IMPROVE AS THE SYSTEM TRACKS FURTHER WESTWARD.
