REMARKS:
310900Z POSITION NEAR 33.7N 136.9E.
31AUG24. TROPICAL DEPRESSION 11W (SHANSHAN), LOCATED APPROXIMATELY 176 
NM SOUTHWEST OF YOKOSUKA, JAPAN, HAS TRACKED EASTWARD AT 11 KNOTS OVER 
THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY DEPICTS 
AN EXPOSED, DEFINED LOW-LEVEL CIRCULATION CENTER (LLCC) EMBEDDED 
WITHIN AN AREA OF STRATOCUMULUS. A 310622Z SSMIS 91 GHZ MICROWAVE 
IMAGE INDICATES WEAKLY DEFINED LOW-LEVEL STRUCTURE ASSOCIATED WITH THE 
LLCC, WITH LIMITED CONVECTIVE BANDING DISPLACED TO THE NORTH. SURFACE 
WINDS ALONG THE COAST OF HONSHU ARE WEAK, GENERALLY LESS THAN 10 
KNOTS, REFLECTING THE WEAKENING OVERALL NATURE OF THE SYSTEM. TD 11W 
IS FORECAST TO TRACK GENERALLY POLEWARD OVER THE NEXT 24 HOURS, 
DISSIPATING AS IT TRACKS SOUTH OF AND OVER CENTRAL HONSHU. NUMERICAL 
MODEL GUIDANCE SUPPORTS THE JTWC TRACK FORECAST 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. MINIMUM CENTRAL PRESSURE AT 310600Z IS 998 MB. MAXIMUM 
SIGNIFICANT WAVE HEIGHT AT 310600Z IS 8 FEET.//
