TROPICAL DEPRESSION (TD) 19W, LOCATED APPROXIMATELY 225 NM EAST OF
HO CHI MINH CITY, VIETNAM, HAS TRACKED WEST-NORTHWESTWARD AT 04
KNOTS OVER THE PAST 06 HOURS. ANIMATED MULTISPECTRAL IMAGERY
INDICATES TD 19W IS BEING SEVERELY IMPACTED BY VERTICAL WIND SHEAR
(VWS). THE LOW LEVEL CIRCULATION CENTER (LLCC) IS NOW FULLY EXPOSED
AND CONVECTION HAS WANED SIGNIFICANTLY. NEARBY SHIP REPORTS CONFIRM
THE INITIAL INTENSITY OF 19W IS BELOW 25 KNOTS. TD 19W WILL CONTINUE
TO TRACK WEST-NORTWESTWARD INTO HIGHER VWS; THEREFORE THE SYSTEM IS
EXPECTED TO STEADILY DECAY ALONG TRACK UNTIL IT MAKES LANDFALL NEAR
140600Z. 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 130600Z IS 8 FEET.//
