REMARKS:
251500Z POSITION NEAR 37.0N 131.8E.
TROPICAL STORM (TS) 16W (GONI), LOCATED APPROXIMATELY 128 NM NORTH 
OF IWAKUNI, JAPAN, HAS TRACKED NORTH-NORTHEASTWARD AT 12 KNOTS OVER
THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED (EIR) SATELLITE 
IMAGERY DEPICTS A FULLY EXPOSED AND ELONGATED LOW LEVEL CIRCULATION 
CENTER WITH DEVELOPING FRONTAL CHARACTERISTICS. THIS IS ESPECIALLY 
EVIDENT ALONG THE NORTHERN PERIPHERY WHERE THE SYSTEM IS ENVELOPED 
IN THE MID-LATITUDE WESTERLY FLOW. A RECENT AMSU CROSS-SECTION 
ANALYSIS FURTHER SHOWS THAT TS GONI HAS BEGUN EXTRA-TROPICAL 
TRANSITION WITH A WEAKER WARM-CORE THAT HAS DROPPED TO 4-KM AND A 
COLD-CORE DEVELOPING NEAR 14-KM. THE FSU CYCLONE PHASE EVOLUTION 
GRAPHIC REVEALS THAT TS 16W IS IN THE PROCESS OF TRANSITIONING FROM 
A WARM-CORE TO A COLD-CORE SYSTEM. THE INITIAL POSITION IS BASED ON 
THE EIR LOOP AND A 250838Z WINDSAT MICROWAVE IMAGE WITH GOOD 
CONFIDENCE. TS GONI WILL CONTINUE TO WEAKEN AS IT TRACKS POLEWARD 
INTO SEA SURFACE TEMPERATURES BELOW 26 CELSIUS AND WILL CONTINUE 
EXTRA-TROPICAL TRANSITION (ETT) AS IT EMBEDS DEEPER INTO THE 
BAROCLINIC ZONE. TS 16W IS FORECAST TO COMPLETE ETT IN 12 HOURS. 
DYNAMIC MODEL GUIDANCE IS IN GOOD AGREEMENT LENDING TO HIGH 
CONFIDENCE IN THE JTWC FORECAST. 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 251200Z IS 18 FEET.//
