REMARKS:
270300Z POSITION NEAR 33.9N 152.9E.
TROPICAL DEPRESSION 29W (TWENTYNINE), LOCATED APPROXIMATELY 536
NM NORTH OF MINAMI TORI SHIMA, HAS TRACKED NORTHEASTWARD AT 13
KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTI-SPECTRAL SATELLITE
IMAGERY (MSI) DEPICTS A FULLY EXPOSED LOW-LEVEL CIRCULATION CENTER
(LLCC) WITH DEEP CONVECTION SHEARED 100NM TO THE NORTHEAST. THE
CURRENT POSITION IS BASED ON THE MSI IMAGERY SHOWING THE EXPOSED
LLCC. THE INITIAL INTENSITY OF 25 KNOTS IS BASED ON THE SHEARED
NATURE OF THE SYSTEM AND THE DVORAK ESTIMATE OF T1.0 (25KTS) FROM
PGTW. TD 29W IS IN AN INCREASINGLY UNFAVORABLE ENVIRONMENT WITH
HIGH (25-30 KNOTS) VERTICAL WIND SHEAR AND IS BECOMING EMBEDDED IN
THE MID-LATITUDE WESTERLIES. THE SYSTEM HAS BEGUN EXTRA-TROPICAL
TRANSITION (ETT) AND IS FORECAST TO COMPLETE ETT BY TAU 24.
AVAILABLE MODEL GUIDANCE IS IN STRONG AGREEMENT THAT THE SYSTEM
WILL CONTINUE TO RECURVE TO THE NORTHEAST. THE JTWC FORECAST TRACK
IS PLACED INSIDE AND SLIGHTLY AHEAD OF THE MULTI-MODEL CONSENSUS
WITH OVERALL HIGH CONFIDENCE. 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. MAXIMUM SIGNIFICANT
WAVE HEIGHT AT 270000Z IS 9 FEET. REFER TO TYPHOON 28W (TRAMI)
WARNINGS (WTPN31 PGTW) FOR SIX-HOURLY UPDATES.//
