TROPICAL STORM 04W (TALIM), LOCATED APPROXIMATELY 171 NM EAST-NORTHEAST OF HANOI, VIETNAM, HAS TRACKED WEST-NORTHWESTWARD AT 08 KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY (MSI) DEPICTS A WELL FORMED TROPICAL CYCLONE THAT HAS MADE LANDFALL FOR ITS FINAL TIME. ANIMATED RADAR IMAGERY AND A 232250Z SSMIS 91GHZ MICROWAVE IMAGE INDICATE A PARTIALLY EXPOSED LOW LEVEL CIRCULATION, LENDING HIGH CONFIDENCE TO THE CURRENT POSITION. AS THE SYSTEM PUSHES INLAND, THE MOUNTAINOUS TERRAIN OF SOUTHERN CHINA WILL RAPIDLY WEAKEN THE SYSTEM UNTIL DISSIPATION NEAR TAU 36. NUMERICAL MODEL GUIDANCE IS IN GOOD AGREEMENT THAT 04W WILL TRACK GENERALLY WESTWARD UNTIL DISSIPATION. 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. MINIMUM CENTRAL PRESSURE AT 180000Z IS 980 MB. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 180000Z IS 25 FEET. // NNNN
