11AUG26. TROPICAL DEPRESSION 14W (CHAN-HOM), LOCATED
APPROXIMATELY 79 NM WEST-NORTHWEST OF CAMP FUJI, HAS TRACKED
WESTWARD AT 21 KNOTS OVER THE PAST SIX HOURS. THE CIRCULATION HAS
BECOME ILL-DEFINED IN SATELLITE AND RADAR IMAGERY, AND SURFACE
OBSERVATIONS OVER JAPAN REVEAL VERY WEAK PRESSURE GRADIENTS AND
NO WELL-DEFINED CIRCULATION PATTERN. MAXIMUM SURFACE WINDS OFFSHORE
TO THE NORTH OF HONSHU WERE UP TO 30 KT IN EARLIER SCATTEROMETER
DATA FROM 111501Z. NUMERICAL MODELS AGREE THAT 14W WILL EMERGE OVER
THE SOUTHERN SEA OF JAPAN AS AN OPEN TROUGH AND CONTINUE QUICKLY
WEAKENING OVER THE NEXT 24 HOURS. THIS IS THE FINAL WARNING ON THIS
SYSTEM BY THE JOINT TYPHOON WRNCEN PEARL HARBOR HI. THE SYSTEM WILL
