TROPICAL DEPRESSION (TD) 01W (ONE), LOCATED APPROXIMATELY 112 NM

SOUTH-SOUTHEAST OF HO CHI MINH CITY, VIETNAM, HAS TRACKED WESTWARD AT

08 KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE

IMAGERY DEPICTS A DECAYING, FULLY-EXPOSED, LOW-LEVEL CIRCULATION

CENTER WITH NO DEEP CONVECTION. THE CURRENT INTENSITY IS ASSESSED AT

25 KNOTS BASED ON DVORAK INTENSITY ESTIMATES OF 25 KNOTS, CONSISTENT

WITH THE WEAKENED STRUCTURE. TD 01W IS TRACKING WESTWARD UNDER THE

STEERING INFLUENCE OF THE LOW- TO MID-LEVEL SUBTROPICAL RIDGE TO THE

NORTH. TD 01W WILL CONTINUE TO WEAKEN WHILE TRACKING WESTWARD AND IS

EXPECTED TO MAKE LANDFALL OVER THE SOUTHERN TIP OF VIETNAM BY TAU

12. DUE TO THE MARGINAL ENVIRONMENT AND INTERACTION WITH LAND, THE

SYSTEM IS EXPECTED TO DISSIPATE BY TAU 12. 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. MAXIMUM

SIGNIFICANT WAVE HEIGHT AT 160000Z IS 6 FEET.//
