REMARKS:

250900Z POSITION NEAR 19.0N 126.1E.

TROPICAL DEPRESSION (TD) 12W (TWELVE), LOCATED APPROXIMATELY 383 NM

NORTHEAST OF MANILA, PHILIPPINES, HAS TRACKED NORTH-NORTHEASTWARD

AT 05 KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE

IMAGERY SHOWS THE WANING CONVECTION HAS BECOME SHEARED SOUTHWESTWARD,

PARTIALLY EXPOSING A WEAK AND UNRAVELING LOW LEVEL CIRCULATION

CENTER. THE INITIAL POSITION IS BASED ON THE ABOVE ANIMATION WITH

FAIR CONFIDENCE. THE INITIAL INTENSITY IS BASED ON AN OVERALL

ASSESSMENT OF DVORAK ESTIMATES FROM PGTW AND KNES AND REFLECTS THE

WEAKENED STATE OF THE SYSTEMS. TD 12W IS EXPECTED TO CONTINUE TO

DETERIORATE DUE TO MODERATE VWS AND SUBSIDENCE ALOFT, LEADING TO ITS

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 250600Z IS 12 FEET. REFER TO TROPICAL STORM 01C (HALOLA) WARNINGS

(WTPN32 PGTW) FOR SIX-HOURLY UPDATES.//
