REMARKS:
082100Z POSITION NEAR 34.9N 138.4E. 08SEP23. 
TROPICAL DEPRESSION 12W (YUN-YEUNG), LOCATED
APPROXIMATELY 84 NM SOUTHWEST OF YOKOSUKA, JAPAN, HAS TRACKED
NORTH-NORTHEASTWARD AT 10 KNOTS OVER THE PAST SIX HOURS.
ANIMATED PROXYVIS SATELLITE IMAGERY (PSI) SHOWS TROPICAL
DEPRESSION (TD) YUN-YEUNG (12W) RAPIDLY WEAKENING OVER THE LAST
SIX HOURS.  THE FULLY EXPOSED LOW-LEVEL CIRCULATION CENTER (LLCC)
HAS UNRAVELED INTO A WAVE LIKE FEATURE AND BEGUN DISSIPATION
OVER WATER. THE SYSTEM IS ANTICIPATED TO IMMINENTLY MAKE
LANDFALL ALONG THE NORTHERN SHORELINE OF THE SURUGA BAY AT
WEAK TROPICAL DEPRESSION INTENSITY.  THE INITIAL POSITION IS
PLACED WITH MEDIUM CONFIDENCE BASED ON A 081800Z HM9 PROXYVIS
SATELLITE IMAGE AND TRIANGULATION FROM NEARBY SURFACE OBSERVATIONS, 
INCLUDING SHIZUHAMA AB AT JUST 15NM TO THE NORTH-NORTHWEST.  THE 
INITIAL INTENSITY IS PLACED WITH MEDIUM CONFIDENCE BASED ON 
PERSISTENCE AND RECENT SCATTEROMETRY DATA. 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. MINIMUM CENTRAL 
PRESSURE AT 081800Z IS 1004 MB. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 
081800Z IS 12 FEET.//
