TROPICAL STORM 29W (CHAMPI), LOCATED APPROXIMATELY 163 NM SOUTHWEST OF SASEBO, JAPAN, HAS TRACKED EAST-NORTHEASTWARD AT 11 KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL IMAGERY DEPICTS TROPICAL STORM (TS) 29W (CHAMPI) AS A HIGHLY ELONGATED AND SHALLOW SYSTEM DEVOID OF CONVECTION. THE 251144Z ASCAT DATA REVEALED THE SYSTEM HAS OPENED INTO A TROUGH, WITH THE STORM-FORCE WINDS CONFINED TO THE NORTHEASTERN HEMISPHERE AND THE COLD SIDE OF THE DEVELOPING FRONTAL SYSTEM. ENVIRONMENTAL ANALYSIS REVEALS A HOSTILE ENVIRONMENT, CHARACTERIZED BY HIGH (30-35 KTS) VERTICAL WIND SHEAR, COLD (25-26 C) SEA SURFACE TEMPERATURES, COPIOUS AMOUNTS OF DRY AIR, AND JET INTERACTION. DETERMINISTIC MODEL GUIDANCE IS IN STRONG AGREEMENT THAT 29W WILL CONTINUE TO TRACK NORTHEASTWARD FOR THE NEXT 24 HOURS WHILE IT FURTHER DEGRADES. ELEVATED SURFACE WINDS ARE POSSIBLE AS THE TROUGH PASSES OVER KYUSHU. 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 251800Z IS 1002 MB. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 251800Z IS 15 FEET. REFER TO TYPHOON 30W (IN-FA) WARNINGS (WTPN31 PGTW) FOR SIX-HOURLY UPDATES.// NNNN
