REMARKS:
051500Z POSITION NEAR 28.8N 130.0E.
05JUN21. TROPICAL DEPRESSION 04W (CHOI-WAN), LOCATED APPROXIMATELY 92
NM NORTH-NORTHEAST OF KADENA AB, HAS TRACKED NORTHEASTWARD AT 27 
KNOTS OVER THE PAST SIX HOURS. THE CURRENT POSITION AND INTENSITY 
ALIGN WITH RECENT ASCAT DATA FROM 051157Z AND 051311Z, WHICH 
INDICATE AN ELONGATING LOW-LEVEL CIRCULATION WITH DECREASING WIND 
SPEEDS NEAR THE CENTER. TD 04W IS TRACKING RAPIDLY NORTHEASTWARD IN 
THE GRADIENT BETWEEN SUBTROPICAL RIDGING TO THE EAST AND A DEEP 
TROUGH TO THE NORTHWEST. STRONG VERTICAL WIND SHEAR (GREATER THAN 20 
KNOTS) AND PASSAGE OVER COOLER WATER (25-26 CELSIUS) ARE INDUCING 
RAPID WEAKENING. CONVECTIVE STRUCTURE HAS COMPLETELY DETERIORATED 
OVER THE PAST SIX HOURS, AND THE ONLY REMAINING DEEP CONVECTION IS 
CONFINED TO A SMALL AREA WELL TO THE NORTHEAST OF THE LOW-LEVEL 
CIRCULATION CENTER. THE SYSTEM WILL DISSIPATE WITHIN THE NEXT 12 
HOURS AS IT TRACKS NORTHEASTWARD UNDER THE CURRENT STEERING 
INFLUENCES. NUMERICAL MODEL GUIDANCE REMAINS IN TIGHT AGREEMENT, AND 
THE TRACK FORECAST LIES NEAR THE MULTI-MODEL CONSENSUS WITH HIGH 
CONFIDENCE. 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. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 
051200Z IS 11 FEET.
