26JUN25. TROPICAL DEPRESSION 02W (SEPAT), LOCATED APPROXIMATELY
213 NM SOUTH-SOUTHEAST OF MISAWA, JAPAN, HAS TRACKED
NORTHEASTWARD AT 18 KNOTS OVER THE PAST SIX HOURS. ANIMATED
MULTISPECTRAL SATELLITE IMAGERY (MSI) DEPICTS TROPICAL DEPRESSION
02W WITH AN INCREASINGLY ELONGATED AND ASYMMETRIC WIND FIELD. THE
SYSTEM HAS STARTED ITS TRANSITION INTO AN EXTRATROPICAL CYCLONE AS
IT APPROACHES THE BAROCLINIC ZONE AND THE UPPER-LEVEL JET. COOL SEA
SURFACE TEMPERATURES OF AROUND 23 C AND 20 KTS WESTERLY VERTICAL WIND
SHEAR INDICATE THAT 02W IS IN AN INCRASINGLY HOSTILE ENVIRONMENT FOR
TROPICAL DEVELOPMENT. 02W IS FORECAST TO CONTINUE ACCELERATING IN
THE NORTHEASTWARD DIRECTION AND COMPLETE EXTRATROPICAL TRANSITION
WITHIN THE NEXT 12 HOURS. AN INCOMING LONG WAVE TROUGH WILL PROPAGATE
EASTWARD AND BEGIN INTERACTING WITH THE SYSTEM, EXPEDITING THE
TRANSITION. BAROCLINIC FORCING WILL ALLOW THE VORTEX TO MARGINALLY
INTENSIFY OVER THE NEXT 24 HOURS AS THE SYSTEM BECOMES AN EXPANSIVE
COLD-CORE LOW. NUMERICAL MODEL GUIDANCE IS IN AGREEMENT REGARDING
BOTH THE TRACK AND INTENSITY OF 02W, LENDING HIGH CONFIDENCE TO 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. MINIMUM CENTRAL PRESSURE AT 260600Z IS
1006 MB. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 260600Z IS 12 FEET.

REASONING NO.11 FOR TD LOCATED AT 31N 140E
1.GENERAL COMMENTS
SEPAT (2502) HAS WEAKENED TO TD INTENSITY. THE TD IS LOCATED AT
31N, 140E. INFORMATION ON THE CURRENT POSITION IS BASED ON
ANIMATED MSI AND SURFACE OBSERVATIONS. CENTRAL PRESSURE IS 1006HPA
AND MAXIMUM SUSTAINED WINDS ARE LESS THAN 30KNOTS. THE SYSTEM IS
IN AN UNFAVORABLE ENVIRONMENT FOR DEVELOPMENT UNDER THE INFLUENCE
OF LOW TCHP AND DRY AIR. THIS HAS CAUSED THE SYSTEM TO WEAKEN OVER
THE LAST SIX HOURS. INFORMATION ON THE CURRENT INTENSITY IS BASED
ON DVORAK INTENSITY ANALYSES AND SURFACE OBSERVATIONS.
2.SYNOPTIC SITUATION
THE SYSTEM IS MOVING NORTH-NORTHWESTWARD ALONG THE SOUTHWESTERN
PERIPHERY OF A MID-LEVEL SUB-TROPICAL HIGH. ANIMATED MSI SHOWS THE
SEPARATION OF ACTIVE CONVECTIVE CLOUD CLUSTERS FROM THE CSC. WATER
VAPOR IMAGERY SHOWS DRY AIR AROUND THE SYSTEM. GCOM-W/AMSR2 89 GHZ
MICROWAVE IMAGERY SHOWS THE SYSTEM HAS ACTIVE CONVECTIVE CLOUD
CLUSTERS AROUND THE CSC.
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.

WTPQ30 RJTD 241200
RSMC TROPICAL CYCLONE PROGNOSTIC REASONING
REASONING NO.10 FOR TS 2502 SEPAT (2502)
1.GENERAL COMMENTS
TS SEPAT IS LOCATED AT 30.6N, 140.1E. INFORMATION ON THE CURRENT
POSITION IS BASED ON ANIMATED MSI AND SURFACE OBSERVATIONS.
POSITIONAL ACCURACY IS GOOD. CENTRAL PRESSURE IS 1004HPA AND
MAXIMUM SUSTAINED WINDS NEAR THE CENTER ARE 35KNOTS. THE SYSTEM IS
IN A NEUTRAL ENVIRONMENT FOR DEVELOPMENT UNDER THE INFLUENCE OF
WEAK VWS, LOW TCHP AND DRY AIR. THIS HAS CAUSED THE SYSTEM TO
MAINTAIN ITS INTENSITY OVER THE LAST SIX HOURS. INFORMATION ON THE
CURRENT INTENSITY IS BASED ON DVORAK INTENSITY ANALYSES AND
SURFACE OBSERVATIONS.
2.SYNOPTIC SITUATION
THE SYSTEM IS MOVING NORTH-NORTHWESTWARD ALONG THE SOUTHWESTERN
PERIPHERY OF A MID-LEVEL SUB-TROPICAL HIGH. ANIMATED MSI SHOWS CB
CLUSTERS ARE SCATTERED AROUND THE CSC. WATER VAPOR IMAGERY SHOWS
DRY AIR IN THE DIRECTION OF THE MOVEMENT. GPM/GMI 89 GHZ MICROWAVE
IMAGERY SHOWS THE SYSTEM HAS ACTIVE CONVECTIVE CLOUD CLUSTERS
AROUND THE CSC.
3.TRACK FORECAST
THE SYSTEM WILL MOVE NORTH-NORTHWESTWARD ALONG THE PERIPHERY OF A
MID-LEVEL SUB-TROPICAL HIGH UNTIL FT24. THE TRACK FORECAST IS
BASED ON GSM PREDICTIONS, AND REFERENCE TO OTHER NWP MODELS. TRACK
FORECAST CONFIDENCE IS FAIR BECAUSE ALL NWP MODELS ARE IN CLOSE
AGREEMENT.
4.INTENSITY FORECAST
THE SYSTEM WILL WEAKEN UNTIL FT12 DUE TO THE INFLUENCE OF
INTERACTION WITH LOW TCHP AND DRY AIR. THE SYSTEM WILL WEAKEN TO
TD INTENSITY BY FT12. THE INTENSITY FORECAST IS BASED ON A
CONSENSUS OF GUIDANCE DATA INCLUDING GSM.

REASONING NO. 9 FOR TS 2502 SEPAT (2502)
1.GENERAL COMMENTS
TS SEPAT IS LOCATED AT 30.1N, 140.4E. INFORMATION ON THE CURRENT
POSITION IS BASED ON ANIMATED MSI AND SURFACE OBSERVATIONS.
POSITIONAL ACCURACY IS GOOD. CENTRAL PRESSURE IS 1004HPA AND
MAXIMUM SUSTAINED WINDS NEAR THE CENTER ARE 35KNOTS. THE SYSTEM IS
IN A NEUTRAL ENVIRONMENT FOR DEVELOPMENT UNDER THE INFLUENCE OF
WEAK VWS, LOW TCHP AND DRY AIR. THIS HAS CAUSED THE SYSTEM TO
MAINTAIN ITS INTENSITY OVER THE LAST SIX HOURS. INFORMATION ON THE
CURRENT INTENSITY IS BASED ON DVORAK INTENSITY ANALYSES AND
SURFACE OBSERVATIONS.
2.SYNOPTIC SITUATION
THE SYSTEM IS MOVING NORTHWESTWARD ALONG THE SOUTHWESTERN
PERIPHERY OF A MID-LEVEL SUB-TROPICAL HIGH. ANIMATED MSI SHOWS CB
CLUSTERS GATHERING AROUND THE CSC. WATER VAPOR IMAGERY SHOWS DRY
AIR AROUND THE SYSTEM. GPM/GMI 89 GHZ MICROWAVE IMAGERY SHOWS THE
SYSTEM HAS ACTIVE CONVECTIVE CLOUD CLUSTERS AROUND THE CSC.
3.TRACK FORECAST
THE SYSTEM WILL MOVE NORTH-NORTHWESTWARD ALONG THE PERIPHERY OF A
MID-LEVEL SUB-TROPICAL HIGH UNTIL FT24. THE TRACK FORECAST IS
BASED ON GSM PREDICTIONS, AND REFERENCE TO OTHER NWP MODELS. TRACK
FORECAST CONFIDENCE IS FAIR UNTIL FT12 BUT LOW THEREAFTER DUE TO
SIGNIFICANT DIFFERENCES AMONG NWP MODEL OUTPUTS.
4.INTENSITY FORECAST
THE SYSTEM WILL WEAKEN UNTIL FT12 DUE TO THE INFLUENCE OF
INTERACTION WITH INCREASED VWS, LOW TCHP AND DRY AIR. THE SYSTEM
WILL WEAKEN TO TD INTENSITY BY FT12. THE INTENSITY FORECAST IS
BASED ON A CONSENSUS OF GUIDANCE DATA INCLUDING GSM.

RSMC TROPICAL CYCLONE PROGNOSTIC REASONING
REASONING NO. 7 FOR TS 2502 SEPAT (2502)
1.GENERAL COMMENTS
TS SEPAT IS LOCATED AT 28.6N, 142.1E. INFORMATION ON THE CURRENT
POSITION IS BASED ON ANIMATED MSI AND SURFACE OBSERVATIONS.
POSITIONAL ACCURACY IS GOOD. CENTRAL PRESSURE IS 1004HPA AND
MAXIMUM SUSTAINED WINDS NEAR THE CENTER ARE 35KNOTS. THE SYSTEM IS
IN A NEUTRAL ENVIRONMENT FOR DEVELOPMENT UNDER THE INFLUENCE OF
HIGH SSTS, WEAK VWS AND DRY AIR. THIS HAS CAUSED THE SYSTEM TO
MAINTAIN ITS INTENSITY OVER THE LAST SIX HOURS. INFORMATION ON THE
CURRENT INTENSITY IS BASED ON DVORAK INTENSITY ANALYSES AND
SURFACE OBSERVATIONS.
2.SYNOPTIC SITUATION
THE SYSTEM IS MOVING NORTH-NORTHWESTWARD ALONG THE SOUTHWESTERN
PERIPHERY OF A MID-LEVEL SUB-TROPICAL HIGH. ANIMATED MSI SHOWS THE
SYSTEM HAS A BAND WITH A CURVATURE SUGGESTING THE CSC. ANIMATED
MSI SHOWS GOOD CLOUD CHARACTERISTICS OF ANTICYCLONIC OUTFLOW.
GCOM-W/AMSR2 89 GHZ MICROWAVE IMAGERY SHOWS THE SYSTEM HAS ACTIVE
CONVECTIVE CLOUD CLUSTERS AROUND THE CSC.
3.TRACK FORECAST
THE SYSTEM WILL MOVE NORTH-NORTHWESTWARD ALONG THE PERIPHERY OF A
MID-LEVEL SUB-TROPICAL HIGH UNTIL FT24. THE TRACK FORECAST IS
BASED ON GSM PREDICTIONS, AND REFERENCE TO OTHER NWP MODELS. TRACK
FORECAST CONFIDENCE IS FAIR BECAUSE ALL NWP MODELS ARE IN CLOSE
AGREEMENT.
4.INTENSITY FORECAST
THE SYSTEM WILL MAINTAIN ITS INTENSITY UNTIL FT12 DUE TO THE
INFLUENCE OF INTERACTION WITH WEAK VWS AND DRY AIR. THE SYSTEM
WILL THEN WEAKEN UNTIL FT24 DUE TO THE INFLUENCE OF INTERACTION
WITH LOWER SSTS AND LOW TCHP. THE SYSTEM WILL WEAKEN TO TD
INTENSITY BY FT24. THE INTENSITY FORECAST IS BASED ON A CONSENSUS
OF GUIDANCE DATA INCLUDING GSM.

REASONING NO. 6 FOR TS 2502 SEPAT (2502)
1.GENERAL COMMENTS
TS SEPAT IS LOCATED AT 27.0N, 143.4E. INFORMATION ON THE CURRENT
POSITION IS BASED ON ANIMATED MSI AND SURFACE OBSERVATIONS.
POSITIONAL ACCURACY IS GOOD. CENTRAL PRESSURE IS 1004HPA AND
MAXIMUM SUSTAINED WINDS NEAR THE CENTER ARE 35KNOTS. THE SYSTEM IS
IN A NEUTRAL ENVIRONMENT FOR DEVELOPMENT UNDER THE INFLUENCE OF
HIGH SSTS, WEAK VWS AND DRY AIR. THIS HAS CAUSED THE SYSTEM TO
MAINTAIN ITS INTENSITY OVER THE LAST SIX HOURS. INFORMATION ON THE
CURRENT INTENSITY IS BASED ON DVORAK INTENSITY ANALYSES AND
SURFACE OBSERVATIONS.
2.SYNOPTIC SITUATION
THE SYSTEM IS MOVING NORTH-NORTHWESTWARD ALONG THE SOUTHWESTERN
PERIPHERY OF A MID-LEVEL SUB-TROPICAL HIGH. ANIMATED MSI SHOWS THE
SEPARATION OF ACTIVE CONVECTIVE CLOUD CLUSTERS FROM THE CSC,
INDICATING INTERFERENCE FROM INTENSIFICATION. WATER VAPOR IMAGERY
SHOWS DRY AIR AROUND THE SYSTEM. DMSP-F18/SSMIS 89 GHZ MICROWAVE
IMAGERY SHOWS THE SYSTEM HAS ACTIVE CONVECTIVE CLOUD CLUSTERS
AROUND THE CSC.
3.TRACK FORECAST
THE SYSTEM WILL MOVE NORTHWESTWARD ALONG THE PERIPHERY OF A
MID-LEVEL SUB-TROPICAL HIGH UNTIL FT24. THE TRACK FORECAST IS
BASED ON GSM PREDICTIONS, AND REFERENCE TO OTHER NWP MODELS. TRACK
FORECAST CONFIDENCE IS FAIR BECAUSE ALL NWP MODELS ARE IN CLOSE
AGREEMENT.
4.INTENSITY FORECAST
THE SYSTEM WILL MAINTAIN ITS INTENSITY UNTIL FT12 DUE TO THE
INFLUENCE OF INTERACTION WITH HIGH SSTS, WEAK VWS AND DRY AIR. THE
SYSTEM WILL THEN WEAKEN UNTIL FT24 DUE TO THE INFLUENCE OF
INTERACTION WITH LOWER SSTS AND LOW TCHP. THE SYSTEM WILL WEAKEN
TO TD INTENSITY BY FT24. THE INTENSITY FORECAST IS BASED ON A
CONSENSUS OF GUIDANCE DATA INCLUDING GSM.

RSMC TROPICAL CYCLONE PROGNOSTIC REASONING
REASONING NO. 5 FOR TS 2502 SEPAT (2502)
1.GENERAL COMMENTS
TS SEPAT IS LOCATED AT 25.8N, 144.0E. INFORMATION ON THE CURRENT
POSITION IS BASED ON ANIMATED MSI AND SURFACE OBSERVATIONS.
POSITIONAL ACCURACY IS GOOD. CENTRAL PRESSURE IS 1004HPA AND
MAXIMUM SUSTAINED WINDS NEAR THE CENTER ARE 35KNOTS. THE SYSTEM IS
IN A NEUTRAL ENVIRONMENT FOR DEVELOPMENT UNDER THE INFLUENCE OF
HIGH SSTS, WEAK VWS AND DRY AIR. THIS HAS CAUSED THE SYSTEM TO
MAINTAIN ITS INTENSITY OVER THE LAST SIX HOURS. INFORMATION ON THE
CURRENT INTENSITY IS BASED ON DVORAK INTENSITY ANALYSES AND
SURFACE OBSERVATIONS.
2.SYNOPTIC SITUATION
THE SYSTEM IS MOVING NORTHWESTWARD ALONG THE SOUTHWESTERN
PERIPHERY OF A MID-LEVEL SUB-TROPICAL HIGH. ANIMATED MSI SHOWS THE
SEPARATION OF ACTIVE CONVECTIVE CLOUD CLUSTERS FROM THE CSC,
INDICATING INTERFERENCE FROM INTENSIFICATION. ANIMATED MSI SHOWS
GOOD CLOUD CHARACTERISTICS OF ANTICYCLONIC OUTFLOW. WATER VAPOR
IMAGERY SHOWS DRY AIR AROUND THE SYSTEM. GCOM-W/AMSR2 89 GHZ
MICROWAVE IMAGERY SHOWS THE SYSTEM HAS ACTIVE CONVECTIVE CLOUD
CLUSTERS AROUND THE CSC.
3.TRACK FORECAST
THE SYSTEM WILL MOVE NORTH-NORTHWESTWARD ALONG THE PERIPHERY OF A
MID-LEVEL SUB-TROPICAL HIGH UNTIL FT48. THE TRACK FORECAST IS
BASED ON GSM PREDICTIONS, AND REFERENCE TO OTHER NWP MODELS. TRACK
FORECAST CONFIDENCE IS FAIR BECAUSE ALL NWP MODELS ARE IN CLOSE
AGREEMENT.
4.INTENSITY FORECAST
THE SYSTEM WILL MAINTAIN ITS INTENSITY UNTIL FT24 DUE TO THE
INFLUENCE OF INTERACTION WITH HIGH SSTS AND LOW TCHP. THE SYSTEM
WILL THEN WEAKEN UNTIL FT48 DUE TO THE INFLUENCE OF LOW TCHP. THE
SYSTEM WILL WEAKEN TO TD INTENSITY BY FT48. THE INTENSITY FORECAST
IS BASED ON A CONSENSUS OF GUIDANCE DATA INCLUDING GSM.

REASONING NO. 4 FOR TS 2502 SEPAT (2502)
1.GENERAL COMMENTS
A TD PREVIOUSLY LOCATED AT 23.9N, 145.2E HAS BEEN UPGRADED TO TS
(SEPAT) STATUS. TS SEPAT IS LOCATED AT 24.5N, 144.7E. INFORMATION
ON THE CURRENT POSITION IS BASED ON ANIMATED MSI AND SURFACE
OBSERVATIONS. POSITIONAL ACCURACY IS GOOD. CENTRAL PRESSURE IS
1004HPA AND MAXIMUM SUSTAINED WINDS NEAR THE CENTER ARE 35KNOTS.
THE SYSTEM IS IN A FAVORABLE ENVIRONMENT FOR DEVELOPMENT UNDER THE
INFLUENCE OF HIGH SSTS AND HIGH TCHP. THIS HAS CAUSED THE SYSTEM
TO DEVELOP OVER THE LAST SIX HOURS. INFORMATION ON THE CURRENT
INTENSITY IS BASED ON DVORAK INTENSITY ANALYSES AND SURFACE
OBSERVATIONS.
2.SYNOPTIC SITUATION
THE SYSTEM IS MOVING NORTHWESTWARD ALONG THE SOUTHWESTERN
PERIPHERY OF A MID-LEVEL SUB-TROPICAL HIGH. ANIMATED MSI SHOWS THE
SEPARATION OF ACTIVE CONVECTIVE CLOUD CLUSTERS FROM THE CSC,
INDICATING INTERFERENCE FROM INTENSIFICATION. ANIMATED MSI SHOWS
GOOD CLOUD CHARACTERISTICS OF ANTICYCLONIC OUTFLOW. WATER VAPOR
IMAGERY SHOWS DRY AIR IN THE DIRECTION OF THE MOVEMENT.
GCOM-W/AMSR2 89 GHZ MICROWAVE IMAGERY SHOWS THE SYSTEM HAS ACTIVE
CONVECTIVE CLOUD CLUSTERS AROUND THE CSC.
3.TRACK FORECAST
THE SYSTEM WILL MOVE NORTH-NORTHWESTWARD ALONG THE PERIPHERY OF A
MID-LEVEL SUB-TROPICAL HIGH UNTIL FT48. THE TRACK FORECAST IS
BASED ON GSM PREDICTIONS, AND REFERENCE TO OTHER NWP MODELS. TRACK
FORECAST CONFIDENCE IS FAIR BECAUSE ALL NWP MODELS ARE IN CLOSE
AGREEMENT.
4.INTENSITY FORECAST
THE SYSTEM WILL MAINTAIN ITS INTENSITY UNTIL FT24 DUE TO THE
INFLUENCE OF INTERACTION WITH WEAK VWS AND REDUCED TCHP. THE
SYSTEM WILL THEN WEAKEN UNTIL FT48 DUE TO THE INFLUENCE OF
INTERACTION WITH LOW TCHP AND DRY AIR. THE SYSTEM WILL WEAKEN TO
TD INTENSITY BY FT48. THE INTENSITY FORECAST IS BASED ON A
CONSENSUS OF GUIDANCE DATA INCLUDING GSM.
