17DEC21. TROPICAL DEPRESSION 29W (TWENTYNINE), LOCATED
APPROXIMATELY 190 NM NORTH-NORTHWEST OF SINGAPORE, HAS
TRACKED WESTWARD AT 10 KNOTS OVER THE PAST SIX HOURS.
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 170000Z
IS 12 FEET. ANIMATED VISIBLE IMAGERY, RADAR DATA FROM THE MALAYSIA
RADAR NETWORK AND SURFACE OBSERVATIONS FROM KUANTAN, MALAYSIS,
INDICATE THAT TD 28W MADE LANDFALL JUST NORTH OF KUANAN NEAR THE
162300Z HOUR AND HAS CONTINUED TO MOVE INLAND. THE ADVANCED DVORAK
TECHNIQUE (ADT) AND SATCON ESTIMATES PRIOR TO LANDFALL WERE AS HIGH
AS T2.5, INDICATING THAT THE SYSTEM LIKELY BRIEFLY REACHED AT LEAST
30 KNOTS PRIOR TO LANDFALL. HOWEVER NOW THAT THE SYSTEM IS OVER
LAND, IT IS ALREADY STARTING TO WEAKEN AND WILL DISSIPATE AS A
TROPICAL CYCLONE OVER LAND WITHIN THE NEXT 12 TO 24 PRIOR TO
REACHING THE WEST COAST OF MALAYSIA. IT IS LIKELY THAT A WEAK,
REMNANT CIRCULATION WILL MOVE OFF THE WEST COAST, BUT IT IS NOT
EXPECTED TO REDEVELOP AT THIS TIME. REFER TO TYPHOON 28W (RAI)
WARNINGS (WTPN31 PGTW) FOR SIX-HOURLY UPDATES.//
