081500Z POSITION NEAR 38.5N 139.4E. TROPICAL DEPRESSION (TD) 07W (NORU), LOCATED APPROXIMATELY 155 NM SOUTHWEST OF MISAWA, JAPAN, HAS TRACKED EAST-NORTHEASTWARD AT 08 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY AND A 081223Z METOP-A 89GHZ IMAGE INDICATE RAPIDLY DECAYING DEEP CONVECTION ASSOCIATED WITH A DISORGANIZED LOW-LEVEL CIRCULATION CENTER (LLCC). ANIMATED RADAR IMAGERY ALSO SHOWS A POORLY-DEFINED LLCC WITH FRAGMENTED BANDING, PRIMARILY OVER LAND. SURFACE OBSERVATIONS ARE GENERALLY LESS THAN 10 KNOTS WITH REPORTS NEAR THE CENTER FROM AWASHIMA NORTHERLY AT 4-6 KNOTS. DVORAK INTENSITY ESTIMATES FROM BOTH PGTW AND RJTD HAVE DECREASED TO 1.5/2.0, REFLECTING THE WEAKENING PHASE, THEREFORE THE INITIAL INTENSITY IS ASSESSED AT 25 KNOTS. TD 07W IS FORECAST TO TRACK EASTWARD OVER HONSHU AND IS EXPECTED TO DISSIPATE OVER LAND BY TAU 12. 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 081200Z IS 7 FEET.
