TROPICAL DEPRESSION 01W (BOLAVEN), LOCATED APPROXIMATELY 268 NM

EAST-NORTHEAST OF HO CHI MINH CITY, VIETNAM, HAS TRACKED

NORTHWESTWARD AT 09 KNOTS OVER THE PAST SIX HOURS. TD 01W IS

DISSIPATING AS IT TRACKS TOWARDS SOUTHERN VIETNAM. ANIMATED

MULTISPECTRAL SATELLITE IMAGERY SHOWS A FULLY EXPOSED LOW-LEVEL

CIRCULATION CENTER WITH DECAYING DEEP CONVECTION SHEARED TO THE

NORTH. THE INITIAL INTENSITY IS ASSESSED AT 25 KNOTS BASED ON THE

PGTW DVORAK CURRENT INTENSITY ESTIMATE OF T1.0 (25 KNOTS). TD 01W IS

FORECAST TO CONTINUE TRACKING WEST-NORTHWESTWARD ALONG THE

SOUTHWESTERN PERIPHERY OF THE SUBTROPICAL RIDGE LOCATED TO THE

NORTHEAST. THE SYSTEM IS FORECAST TO RAPIDLY DISSIPATE AFTER IT

MAKES LANDFALL NORTH OF HO CHI MINH, VIETNAM. NUMERICAL MODEL

GUIDANCE REMAINS IN GOOD AGREEMENT; THEREFORE, THERE IS HIGH

CONFIDENCE IN THE JTWC OFFICIAL FORECAST TRACK. 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 040000Z IS 10 FEET.//
