REMARKS:
080300Z POSITION NEAR 39.9N 149.9E.
08JUL25. TROPICAL DEPRESSION 04W (MUN), LOCATED APPROXIMATELY 370
NM EAST OF MISAWA, JAPAN, HAS TRACKED NORTH-NORTHEASTWARD AT 14
KNOTS OVER THE PAST SIX HOURS. ALL DEEP CONVECTION HAS COLLAPSED
AS THE COOLER SEA SURFACE CAN NO LONGER SUPPORT A WARM CORE SYSTEM.
THE SYSTEM IS ENTERING A TRANSITION PHASE TO A SUBTROPICAL CYCLONE.
STRATOCUMULUS FIELDS ARE SHOWING THE EARLY SIGNS OF RELAXING AND
EXPANDING AWAY FROM THE EXPOSED LOW LEVEL CIRCULATION CENTER BUT
ENOUGH MOMENTUM EXISTS TO SUSTAIN THE SYSTEM ANOTHER 24 HOURS.
THE JETSTREAM EXTENDS OVER THE KURILS SO THE SYSTEM HAS TOO FAR
TO GO BEFORE IT UNDERGOES THE EXTRA-TROPICAL TRANSITION PROCESS T
YPICAL OF WESTPAC. TD MUN IS COOLING FROM BELOW AND WILL LOSE ITS
WARM CORE DURING THE NEXT 24 HOURS BEFORE IT GETS TO THE BAROCLINIC
ZONE.  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. MINIMUM CENTRAL PRESSURE AT 080000Z IS
1001 MB. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 080000Z IS 12 FEET.
