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.// +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ To unsubscribe from WX-TROPL send e-mail to LISTSERV@LISTSERV.ILLINOIS.EDU with "unsub wx-tropl" in the body of your message.
