REMARKS:
270300Z POSITION NEAR 12.4N 108.5E.
27OCT21. TROPICAL DEPRESSION 26W (TWENTYSIX), LOCATED
APPROXIMATELY 159 NM EAST-NORTHEAST OF HO CHI MINH CITY, VIETNAM, HAS
TRACKED WEST-NORTHWESTWARD AT 06 KNOTS OVER THE PAST SIX HOURS.
ANIMATED MULTISPECTRAL SATELLITE IMAGERY DEPICTS THAT THE SYSTEM HAS
MOVED OVER THE RUGGED TERRAIN OF CENTRAL VIETNAM. THE POSITION IS
FURTHER CONSTRAINED BY THE CONVECTIVE BANDS THAT HAVE PERSISTED IN
THE COMPOSITE RADAR LOOP. NUMERICAL MODEL GUIDANCE IS IN TIGHT
AGREEMENT THAT TD 26W WILL CONTINUE TO TRACK EASTWARD AND MOVE
FARTHER INLAND. THIS WILL LEAD TO DISSIPATION BY TAU 12 AS THE
SYSTEM INTERACTIONS WITH THE UNDERLYING TERRAIN. 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 270000Z IS 12 FEET. REFER TO
TYPHOON 25W (MALOU) WARNINGS (WTPN31 PGTW) FOR SIX-HOURLY UPDATES.
