TROPICAL DEPRESSION (TD) 29W (KROSA), LOCATED APPROXIMATELY 246 NM
SOUTH-SOUTHWEST OF HONG KONG, HAS TRACKED SOUTHWESTWARD AT 11 KNOTS
OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY
SHOWS THE LOW LEVEL CIRCULATION CENTER HAS BECOME FULLY EXPOSED AND
STRIPPED OF ANY SIGNIFICANT CONVECTION. THE INITIAL POSITION IS BASED
ON THE ABOVE ANIMATION WITH HIGH CONFIDENCE. THE INITIAL INTENSITY IS
DEDUCED FROM DVORAK ESTIMATES FROM ALL AGENCIES AND REFLECTS THE
RAPID WEAKENING TREND. TD 29W IS EXPECTED TO WEAKEN TO BELOW THE
25-KNOT WARNING THRESHOLD BY TAU 12 AS PERSISTENTLY HIGH VERTICAL
WIND SHEAR CONTINUES TO ERODE THE SYSTEM. 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 18 FEET. REFER TO TROPICAL
DEPRESSION 30W (THIRTY) WARNINGS (WTPN32 PGTW) FOR SIX-HOURLY
UPDATES. REFER TO TROPICAL STORM 31W (THIRTYONE) WARNINGS (WTPN33
