REMARKS:
220300Z POSITION NEAR 5.2N 106.4E.
TROPICAL DEPRESSION (TD) 32W (KAI-TAK), LOCATED APPROXIMATELY 297 NM
NORTH-NORTHEAST OF SINGAPORE, HAS TRACKED SOUTHWESTWARD AT 07 KNOTS
OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY
(MSI) SHOWS THE CENTRAL CONVECTION HAS SHEARED MORE THAN 180 NM
WESTWARD OF A FULLY EXPOSED AND RAGGED LOW LEVEL CIRCULATION (LLC).
THE INITIAL POSITION IS BASED ON THE MSI LOOP WITH HIGH CONFIDENCE.
THE INITIAL INTENSITY IS BASED ON THE 212308Z WSAT BULLSEYE PASS
SHOWING SPARSE 25-KNOT WIND BARBS NEAR THE CORE. UPPER LEVEL ANALYSIS
INDICATES THE SYSTEM HAS DRIFTED INTO AN AREA OF STRONG (30-40 KNOT)
EASTERLY VERTICAL WIND SHEAR (VWS) AND LIMITED OUTFLOW. THE LLC IS
EXPECTED TO FURTHER UNRAVEL AND DISPERSE AS HIGH VWS PERSISTS LEADING
TO DISSIPATION BY TAU 12. 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 220000Z IS 16 FEET. REFER TO TROPICAL STORM 33W (TEMBIN) WARNINGS
(WTPN32 PGTW) FOR SIX-HOURLY UPDATES.
