RSMC TROPICAL CYCLONE PROGNOSTIC REASONING
REASONING NO.16 FOR EXTRATROPICAL CYCLONE LOCATED AT 45N 145E
1.GENERAL COMMENTS
NARI (2505) HAS TRANSFORMED INTO AN EXTRATROPICAL CYCLONE. THE
EXTRATROPICAL CYCLONE IS LOCATED AT 45N, 145E. INFORMATION ON THE
CURRENT POSITION IS BASED ON ANIMATED MSI AND SURFACE
OBSERVATIONS. CENTRAL PRESSURE IS 998HPA AND MAXIMUM SUSTAINED
WINDS ARE 35KNOTS. THE SYSTEM IS IN AN UNFAVORABLE ENVIRONMENT FOR
DEVELOPMENT UNDER THE INFLUENCE OF LOW SSTS, LOW TCHP AND STRONG
VWS. THIS HAS CAUSED THE SYSTEM TO WEAKEN OVER THE LAST SIX HOURS.
INFORMATION ON THE CURRENT INTENSITY IS BASED ON SURFACE
OBSERVATIONS AND DVORAK INTENSITY ANALYSES.
2.SYNOPTIC SITUATION
THE SYSTEM IS MOVING NORTH-NORTHEASTWARD ALONG THE NORTHWESTERN
PERIPHERY OF A MID-LEVEL SUB-TROPICAL HIGH. ANIMATED MSI SHOWS THE
SYSTEM IS ONLY A VORTEX CONSISTING OF LOW-LEVEL CLOUDS.
3.TRACK FORECAST
SEE THE MARINE WARNING (WWJP27 RJTD).
4.INTENSITY FORECAST
SEE THE MARINE WARNING (WWJP27 RJTD).
5.REMARKS
THIS WILL BE THE FINAL PROGNOSTIC REASONING FOR THE SYSTEM.

REMARKS:
142100Z POSITION NEAR 43.6N 144.6E.
14JUL25. TROPICAL STORM 06W (NARI), LOCATED APPROXIMATELY 166 NM
NORTHEAST OF MISAWA, JAPAN, HAS TRACKED NORTH-NORTHEASTWARD AT 29
KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED (EIR)
SATELLITE IMAGERY DEPICTS 06W WITH AN EXPOSED LOW-LEVEL CIRCULATION
CENTER (LLCC) THAT IS PASSING OVER THE EASTERN EXTENT OF HOKKAIDO.
THE STRONGEST WINDS REMAIN WITHIN THE SOUTHEASTERN QUADRANT, WHICH
IS EXPECTED TO REMAIN THE CASE OVER THE NEXT 24 HOURS. 06W IS
FORECAST TO BEGIN TRACKING MORE EAST-NORTHEASTWARD AS INTERACTION
WITH THE JET TO THE NORTH INCREASES. EXTRATROPICAL TRANSITION IS
FORECAST TO COMPLETE AT TAU 12 AS WESTERLY SHEAR RAPIDLY INCREASES
AND SEA SURFACE TEMPERATURES DRASTICALLY DROP (BELOW 18 C).
THESE ENVIRONEMNTAL FACTORS WILL ALSO AID IN THE WEAKENING OF THE
VORTEX OVER THE NEXT 24 HOURS AS THE SYSTEM BECOMES ABSORBED BY
THE STRONG UPPER-LEVEL WESTERLY FLOW. NUMERICAL MODEL TRACK GUIDANCE
IS IN GOOD AGREEMENT WITH MINIMAL CROSS-TRACK AND ALONG-TRACK
SPREAD. INTENSITY GUIDANCE IS ALSO IN GOOD AGREEMENT WITH ALL MODELS
DEPICTING STEADY WEAKENING THROUGHOUT THE FORECAST PERIOD.
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 141800Z IS 993
MB. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 141800Z IS 20 FEET.
