REMARKS:
120900Z POSITION NEAR 33.4N 155.7E.
TYPHOON 23W (SONGDA), LOCATED APPROXIMATELY 770 NM SOUTHEAST OF
MISAWA, JAPAN, HAS TRACKED EAST-NORTHEASTWARD AT 27 KNOTS OVER THE
PAST SIX HOURS. ANIMATED ENHANCED INFRARED (EIR)SATELLITE IMAGERY
SHOWS THE SYSTEM HAS MAINTAINED A 23NM, ALBEIT MORE RAGGED, EYE EVEN
AS THE CENTRAL CONVECTION HAS BEGUN TO COLLAPSE AS EVIDENCED BY THE
WARMING CLOUD TOPS. ADDITIONALLY, THE OVERALL STRUCTURE HAS BECOME
MORE ASYMMETRIC WITH SEVERE ELONGATION AND DISPERSION ALONG THE
NORTHERN PERIPHERIES. THE INITIAL POSITION IS BASED WITH HIGH
CONFIDENCE ON THE EYE FEATURE IN THE EIR LOOP THAT LINED UP WELL WITH
A LOW REFLECTIVITY CIRCULATION CENTER IN THE 120458Z SSMI-S MICROWAVE
PASS. THE INITIAL INTENSITY IS BASED ON AGENCY DVORAK ESTIMATES AND
REFLECTS THE WEAKENED STATE OF THE TYPHOON. UPPER LEVEL ANALYSIS
INDICATES THE CYCLONE HAS EMBEDDED DEEPER IN THE MID-LATITUDE
WESTERLIES. CONSEQUENTLY, THE POLEWARD OUTFLOW HAS FURTHER
INTENSIFIED, PROVIDING EXCELLENT VENTILATION TO THE REMNANT
CONVECTION; HOWEVER, STRONG (GREATER THAN 30 KNOTS) VERTICAL WIND
SHEAR, WITH IN-PHASE STORM MOTION ACCOUNTED FOR, HAS EASILY OFFSET
THE OUTFLOW. ADDITIONALLY, ALONG-TRACK SEA SURFACE TEMPERATURES HAVE
DIPPED TO 26C AND GETTING COLDER. TY 23W HAS ALSO CROSSED INTO THE
BAROCLINIC ZONE AND IS NOW UNDERGOING EXTRA-TROPICAL TRANSITION
(ETT). ALTHOUGH THE CYCLONE IS STILL A STRONG TYPHOON, THE COMBINED
NEGATIVE EFFECTS OF THE ENVIRONMENT WILL RAPIDLY ERODE THE SYSTEM.
HOWEVER, BEFORE TOTAL DISSIPATION SETS IN, TY SONGDA WILL COMPLETE
ETT AND BECOME A WHOLE GALE-FORCE COLD-CORE LOW IN 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. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 120600Z IS 26 FEET.//
