REMARKS 180300Z2 POSITION NEAR 17.3N1 140.3E8.
TROPICAL DEPRESSION (TD) 12W, LOCATED APPROXIMATELY 320 NM
NORTHWEST OF ANDERSEN AFB, GUAM, HAS TRACKED NORTHWESTWARD
AT 14 KNOTS OVER THE PAST 06 HOURS. THE WARNING POSITION IS
BASED ON A 172330Z6 MULTISPECTRAL SATELLITE IMAGE AND
EXTRAPOLATION. THE WARNING INTENSITY IS BASED ON SATELLITE
CURRENT INTENSITY ESTIMATES OF 25 KNOTS. A LOW LEVEL
CIRCULATION CENTER COULD NOT BE FOUND IN MULTISPECTRAL
SATELLITE IMAGERY AND OTHER SOURCES SUCH AS QUIKSCAT AND
SHIP REPORTS DESPITE A THOROUGH INVESTIGATION. IT IS CONCLUDED
THAT TD 12W CONTINUES TO HAVE A SURFACE WIND PATTERN CONSISTENT
WITH A SURFACE TROUGH AND NO LONGER MEETS WARNING CRITERIA.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 180000Z9 IS 11 FEET. REFER
TO WWPW30 RJTX FOR ADDITIONAL SEA HEIGHT INFORMATION. THIS IS
THE FINAL WARNING ON THIS SYSTEM BY THE JOINT TYPHOON WARNING
CENTER (NAVPACMETOCCEN). THE SYSTEM WILL BE CLOSELY MONITORED
FOR SIGNS OF REGENERATION.//
