SOUTHEAST OF YOKOSUKA, JAPAN, HAS TRACKED WESTWARD AT 05
KNOTS OVER THE PAST SIX HOURS. TS 15E HAS TURNED WESTWARD, AGAINST
THE PREVIOUSLY FORECASTED RECURVE TOWARD THE NORTHEAST. THE
SYSTEM HAS WEAKENED QUICKLY AND BECOME SHALLOW, NOW DRIVEN BY
LOW-LEVEL FLOW. TS 15E IS ACQUIRING HYBRID CHARACTERISTICS AS IT
STRADDLES THE 26 DEGREE CELSIUS ISOTHERM AND PULLS COLDER AIR INTO
ITS CIRCULATION, BECOMING A SUBTROPICAL DEPRESSION BY TAU 12. OVER
THE NEXT 24-36 HOURS, THE HYBRID SYSTEM WILL GRADUALLY WEAKEN,
OPENING INTO A TROUGH AS THE VERTICAL WIND SHEAR INCREASES TO
40-60 KTS. A LARGE AREA OF 25-30 KT NORTHEASTERLY WINDS WILL MOVE
OVER THE WATERS OFF THE COAST OF CENTRAL HONSHU AT THE END OF
THE FORECAST PERIOD.
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 101200Z IS 999
