REMARKS:
072100Z POSITION NEAR 38.7N 150.0E.
TROPICAL STORM 23W (CHOI-WAN), LOCATED APPROXIMATELY 460 NM EAST-
SOUTHEAST OF MISAWA, JAPAN, HAS TRACKED NORTHWARD AT 38 KNOTS
OVER THE PAST SIX HOURS. THE CURRENT STORM POSITION IS BASED ON 
RECENT FIXES FROM PGTW AND RJTD. THE INTENSITY OF 60 KNOTS IS 
CONSISTENT WITH BOTH SUBJECTIVE AND AUTOMATED INTENSITY ESTIMATES 
FROM MULTIPLE REPORTING AGENCIES. TS 23W IS RAPIDLY MERGING WITH A 
MID-LATITUDE TROUGH. THIS INTERACTION IS GENERATING A VERY INTENSE 
EXTRATROPICAL LOW PRESSURE SYSTEM WITH AN EXTENSIVE AREA OF 
ASSOCIATED LOW-LEVEL WINDS EXCEEDING GALE FORCE. EXTRATROPICAL 
TRANSITION IS EXPECTED TO COMPLETE WITHIN THE NEXT SEVERAL HOURS AS 
THE CIRCULATION CONTINUES TRACKING POLEWARD. THEREFORE, THIS IS THE 
FINAL WARNING ON THIS SYSTEM BY THE JOINT TYPHOON WRNCEN PEARL 
HARBOR HI. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 071800Z IS 36 FEET.//
