TROPICAL DEPRESSION 19W (GUCHOL), LOCATED APPROXIMATELY 212 NM

SOUTHWEST OF TAIPEI, TAIWAN, HAS TRACKED NORTH-NORTHWESTWARD AT 08

KNOTS OVER THE PAST SIX HOURS.  ANIMATED ENHANCED INFRARED SATELLITE

IMAGERY SHOWS SIGNIFICANTLY WEAKENING CONVECTION THAT HAS BEEN

SHEARED TO THE WEST OF THE FULLY-EXPOSED LOW LEVEL CIRCULATION CENTER

(LLCC).  THE POSITION IS BASED ON A WEAK CIRCULATION FEATURE IN THE

INTENSITY IS BASED ON 1.0 AND 1.5 DVORAK ESTIMATES FROM PGTW AND

RJTD, RESPECTIVELY.  ENVIRONMENTAL ANALYSIS SHOWS LIMITED UPPER LEVEL

OUTFLOW AND STRONG VERTICAL WIND SHEAR.  THIS SYSTEM IS RAPIDLY

WEAKENING AND WILL DISSIPATE OVER WATER BY TAU 12.  THEREFORE, THIS

IS THE FINAL WARNING ON THIS SYSTEM BY THE JOINT TYPHOON WRNCEN PEARL
