REMARKS:
041500Z POSITION NEAR 31.5N 120.3E.
04AUG20. TROPICAL DEPRESSION 03W (HAGUPIT), LOCATED APPROXIMATELY
71 NM WEST-SOUTHWEST OF SHANGHAI, CHINA, HAS TRACKED NORTHWARD AT
10 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED (EIR)
SATELLITE IMAGERY DEPICTS A PARTIALLY EXPOSED LOW LEVEL CIRCULATION
CENTER (LLCC) WITH FLARING CONVECTION SHEARED OVER THE SOUTHEAST
QUADRANT. THE POSITION IS PLACED WITH HIGH CONFIDENCE BASED ON A
COMBINATION OF PGTW AND RJTD FIXES AND THE PRESENCE OF A BROAD LOW
LEVEL CIRCULATION FEATURE IN THE COMPOSITE RADAR LOOP. THE INTENSITY
IS PLACED WITH HIGH CONFIDENCE BASED ON MULTIPLE SURFACE OBSERVATIONS
THAT HAVE CONTINUED TO DEPICT A WEAKENING SYSTEM. TD HAGUPIT WILL
CONTINUE TO WEAKEN OVER THE NEXT 24 HOURS DUE TO A MIXTURE OF TERRAIN
EFFECTS, HIGH (25+ KTS) VERTICAL WIND SHEAR AND LACK OF UPPER LEVEL
OUTFLOW. BY TAU 12 THE SYSTEM WILL MOVE INTO THE YELLOW SEA AND
DISSIPATE OVER WATER. DESPITE DISSIPATION, GALE FORCE WINDS
ASSOCIATED WITH DEEP SOUTHERLY FLOW OVER THE EAST CHINA SEA ARE
FORECAST TO PERSIST. DYNAMIC MODEL SOLUTIONS ARE IN TIGHT AGREEMENT,
LENDING HIGH OVERALL CONFIDENCE TO THE JTWC FORECAST TRACK. 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.//
