REMARKS:
032100Z POSITION NEAR 32.6N 144.8E.
TROPICAL STORM 20W (MALIKSI), LOCATED APPROXIMATELY 330 NM SOUTHEAST
OF YOKOSUKA, JAPAN, HAS ACCELERATED NORTH-NORTHEASTWARD AT 32 KNOTS
OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY
SHOWS THE CENTRAL CONVECTION HAS BECOME GREATLY SHEARED TO THE NORTH-
EAST, PARTIALLY EXPOSING THE LOW LEVEL CIRCULATION CENTER (LLCC). THE
SAME ANIMATION SHOWS COLD AIR STRATOCUMULUS CLOUDS ADVECTING INTO THE
LLCC FROM THE NORTHWEST, AN INDICATION OF BAROCLINICITY. THE INITIAL
POSITION IS BASED ON A 031604Z 37 GHZ TRMM COLOR COMPOSITE AND FROM
THE 031800Z RJTD FIX WITH FAIR CONFIDENCE. THE INITIAL INTENSITY IS
BASED ON CONGRUENT DVORAK ESTIMATES FROM MULTIPLE AGENCIES. UPPER
LEVEL ANALYSIS INDICATES TS 20W IN NOW WELL NORTH OF THE RIDGE AXIS
IN AN AREA OF VERY STRONG SOUTHWESTERLY VERTICAL WIND SHEAR (30-50
KNOTS). IT IS TRACKING ALONG THE NORTHWEST PERIPHERY OF A DEEP-
LAYERED SUBTROPICAL RIDGE TO THE EAST. TS MALIKSI IS NOW UNDERGOING
EXTRA-TROPICAL TRANSITION AND WILL BECOME A COLD CORE LOW BY TAU 12.
THE AVAILABLE NUMERICAL GUIDANCE IS IN TIGHT AGREEMENT WITH THIS
TRACK FORECAST THAT IS LAID WITH 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 031800Z IS 18 FEET. REFER TO
TROPICAL STORM 21W (GAEMI)WARNINGS (WTPN31 PGTW) FOR SIX-HOURLY
UPDATES.//
