REMARKS:
161500Z POSITION NEAR 29.0N 155.7E.
TROPICAL STORM (TS) 25W (HAISHEN), LOCATED APPROXIMATELY 675 NM
EAST OF CHICHI JIMA, HAS TRACKED EAST-NORTHEASTWARD AT 20 KNOTS 
OVER THE PAST SIX HOURS. THE STORM IS RAPIDLY TRANSITIONING INTO
AN EXTRATROPICAL SYSTEM AHEAD OF A STRONG BAROCLINIC BOUNDARY. 
THE STORM HAS LOST MUCH OF ITS DEEP CONVECTION AND ANY REMAINING
CONVECTION HAS BEEN LIMITED TO THE NORTHEASTERN QUADRANT. FRONTAL
FEATURES HAVE BECOME INCREASINGLY MORE PRONOUNCED IN COMPARISON OF
MULTIPLE MICROWAVE IMAGES OVER THE PAST 12 HOURS. THE STORM HAS 
BEGUN TO ACCELERATE POLEWARD, NORTH OF THE SUBTROPICAL RIDGE AXIS,
AND INTO THE MID-LATITUDE WESTERLIES. THIS IS THE FINAL WARNING ON 
THIS SYSTEM BY THE JOINT TYPHOON WARNING CENTER (NAVMARFCSTCEN).
THE SYSTEM WILL BE CLOSELY MONITORED FOR SIGNS OF REGENERATION. 
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 161200Z IS 9 FEET. REFER TO 
TROPICAL STORM 26W (NOUL) WARNINGS (WTPN32 PGTW) FOR SIX-HOURLY 
UPDATES.
