REMARKS:
062100Z POSITION NEAR 39.9N 154.6E.
06SEP24. TROPICAL STORM 13W (LEEPI), LOCATED APPROXIMATELY 567 NM
EAST OF MISAWA, JAPAN, HAS TRACKED NORTHEASTWARD AT 22 KNOTS OVER
THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED (EIR) SATELLITE IMAGERY
DEPICTS A SMALL AND SHALLOW LOW LEVEL CIRCULATION CENTER (LLCC),
MOVING RAPIDLY NORTHEASTWARD UNDER STRONG UPPER-LEVEL SOUTHWESTERLY
FLOW INDICATED BY A BROAD REGION OF CIRRUS STREAMERS. MANUAL AND
AUTOMATED PHASE CLASSIFICATION WORKSHEETS AS WELL AS A FSU PHASE SPACE
DIAGRAM SHOW THE SYSTEM AS A SUBTROPICAL OR HYBRID, SYSTEM, WITH
CHARACTERISTICS OF BOTH A TROPICAL AND EXTRATROPICAL LOW. THE JTWC
ASSESSMENT IS THAT THE SYSTEM IS UNDERGOING EXTRATROPICAL TRANSITION
(ETT), HAVING CROSSED NORTH OF THE 26C ISOTHERM, MOVING INTO A
BAROCLINIC ZONE AND THERMAL RIBBON, AND EMBEDDING IN PHASE WITH A
500MB SHORTWAVE TROUGH. THE SYSTEM WILL CONTINUE TO ACCELERATE
NORTHEASTWARD WHILE UNDERGOING ETT, WHILE MAINTAINING ITS CURRENT
INTENSITY OF 35 KNOTS. FULL TRANSITION TO A WEAK GALE-FORCE LOW
PRESSURE AREA IS EXPECTED WITHIN THE NEXT 12 HOURS. 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 061800Z IS 1003 MB. MAXIMUM SIGNIFICANT
WAVE HEIGHT AT 061800Z IS 16 FEET. REFER TO TYPHOON 12W (YAGI)
WARNINGS (WTPN31 PGTW) FOR SIX-HOURLY UPDATES.
