REMARKS:
260900Z POSITION NEAR 38.0N 144.1E.
26JUN25. TROPICAL DEPRESSION 02W (SEPAT), LOCATED APPROXIMATELY
213 NM SOUTH-SOUTHEAST OF MISAWA, JAPAN, HAS TRACKED
NORTHEASTWARD AT 18 KNOTS OVER THE PAST SIX HOURS. ANIMATED
MULTISPECTRAL SATELLITE IMAGERY (MSI) DEPICTS TROPICAL DEPRESSION
02W WITH AN INCREASINGLY ELONGATED AND ASYMMETRIC WIND FIELD. THE
SYSTEM HAS STARTED ITS TRANSITION INTO AN EXTRATROPICAL CYCLONE AS
IT APPROACHES THE BAROCLINIC ZONE AND THE UPPER-LEVEL JET. COOL SEA
SURFACE TEMPERATURES OF AROUND 23 C AND 20 KTS WESTERLY VERTICAL WIND
SHEAR INDICATE THAT 02W IS IN AN INCREASINGLY HOSTILE ENVIRONMENT FOR
TROPICAL DEVELOPMENT. 02W IS FORECAST TO CONTINUE ACCELERATING IN
THE NORTHEASTWARD DIRECTION AND COMPLETE EXTRATROPICAL TRANSITION
WITHIN THE NEXT 12 HOURS. AN INCOMING LONG WAVE TROUGH WILL PROPAGATE
EASTWARD AND BEGIN INTERACTING WITH THE SYSTEM, EXPEDITING THE
TRANSITION. BAROCLINIC FORCING WILL ALLOW THE VORTEX TO MARGINALLY
INTENSIFY OVER THE NEXT 24 HOURS AS THE SYSTEM BECOMES AN EXPANSIVE
COLD-CORE LOW. NUMERICAL MODEL GUIDANCE IS IN AGREEMENT REGARDING
BOTH THE TRACK AND INTENSITY OF 02W, LENDING HIGH CONFIDENCE TO THE
JTWC FORECAST. 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 260600Z IS
1006 MB. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 260600Z IS 12 FEET.
