REMARKS:
141500Z POSITION NEAR 35.5N 159.7E.
14OCT25. TYPHOON 29W (NAKRI), LOCATED APPROXIMATELY 703 NM NORTH-
NORTHEAST OF MINAMI TORI SHIMA, HAS TRACKED EASTWARD AT 28 KNOTS
OVER THE PAST SIX HOURS. TYPHOON (TY) 29W HAS BEGUN EXTRATROPICAL
TRANSITION (ETT), BASED ON FSU PHASE-SPACE DIAGRAMS, MANUAL PHASE
CLASSIFICATION WORKSHEETS AND ON THE OVERALL STRUCTURAL CHANGES SEEN
IN A 141004Z ASCAT-C PASS, WHICH SHOWS AN ELONGATED LOW LEVEL
CIRCULATION CENTER (LLCC) AND A STRONG WARM FRONTAL SIGNATURE. A
141004Z AMSU-B 89GHZ MICROWAVE IMAGE REVEALED A HIGHLY ASYMMETRIC
STRUCTURE, WITH A DELTA RAIN REGION IN THE NORTHEASTERN SECTOR, ALONG
AND NEAR THE WARM FRONT, PROVIDING ADDITIONAL CONFIRMATION THAT THE
SYSTEM IS IN THE THROWS OF ETT. ANIMATED EIR IMAGERY ALSO SHOWS A
RAPIDLY DETERIORATING STRUCTURE, THOUGH THE SYSTEM RETAINS SOME
TROPICAL-LIKE CHARACTERISTICS PARTICULARLY IN THE UPPER-LEVEL OUTFLOW
STUCTURE. ENVIRONMENTAL CONDITIONS ARE HIGHLY UNFAVORABLE, WITH SHEAR
EXCEEDING 35 KNOTS, SSTS WELL BELOW 26C AND ROBUST POLEWARD OUTFLOW
INTO THE RIGHT REAR ENTRANCE REGION OF A 150 KNOT JET MAX. THE SYSTEM
WILL CONTINUE TRACKING EASTWARD THROUGH THE FORECAST PERIOD, ALONG
THE NORTHERN PERIPHERY OF A DEEP SUBTROPICAL RIDGE (STR) TO THE
SOUTH. TY 29W IS FORECAST TO TRANSITION INTO STRONG STORM-FORCE,
COLD-CORE, MID-LATITUDE CYCLONE WITHIN THE NEXT 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.
MINIMUM CENTRAL PRESSURE AT 141200Z IS 979 MB. MAXIMUM SIGNIFICANT
WAVE HEIGHT AT 141200Z IS 33 FEET.//
