REMARKS:
191500Z POSITION NEAR 10.4N 110.2E.
TROPICAL DEPRESSION (TD) 27W (WASHI), LOCATED APPROXIMATELY 235 NM
EAST OF HO CHI MINH CITY, VIETNAM, HAS TRACKED WEST-NORTHWESTWARD
AT 12 KNOTS OVER THE PAST SIX HOURS. ANIMATED INFRARED SATELLITE
IMAGERY SHOWS CONVECTIVE BANDING HAS SIGNIFICANTLY WEAKENED AND
DISPERSED AS THE LOW LEVEL CIRCULATION HAS BECOME ILL-DEFINED. THE
INITIAL POSITION WAS EXTRAPOLATED FROM MULTISPECTRAL SATELLITE
IMAGERY ANIMATION AND FROM A LOW REFLECTIVITY HOOK FEATURE ON A
191039Z SSMIS MICROWAVE IMAGE. THE INITIAL INTENSITY WAS BASED FROM
DVORAK ESTIMATES FROM PGTW, RJTD, AND KNES. UPPER LEVEL ANALYSIS
INDICATES 15-25 KNOT VERTICAL WIND SHEAR PERSISTS OVER THE SYSTEM.
THE LOW LEVEL HAS BECOME EMBEDDED IN A SHEARLINE BOUNDARY EXTENDING
INTO THE SOUTH CHINA SEA AND IS EXPECTED TO DISSIPATE OVER WATER BY
TAU 12. MOST OF THE AVAILABLE MODEL INTENSITY GUIDANCE IS IN
AGREEMENT WITH DISSIPATION. THIS IS THE FINAL WARNING ON THIS SYSTEM
BY THE JOINT TYPHOON WARNING CENTER (NAVMARFCSTCEN).  THE SYSTEM
WILL BE CLOSELY MONITORED FOR SIGNS OF REGENERATION. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 191200Z IS 9 FEET.//
