WTPQ30 RJTD 050000
RSMC TROPICAL CYCLONE PROGNOSTIC REASONING
REASONING NO.25 FOR TS 2103 CHOI-WAN (2103)
1.GENERAL COMMENTS
TS CHOI-WAN IS LOCATED AT 24.7N, 123.7E. INFORMATION ON THE
CURRENT POSITION IS BASED ON SURFACE OBSERVATIONS AND ANIMATED
MSI. POSITIONAL ACCURACY IS FAIR. CENTRAL PRESSURE IS 1002HPA AND
MAXIMUM SUSTAINED WINDS ARE 35KNOTS. THE SYSTEM IS IN A NEUTRAL
ENVIRONMENT FOR DEVELOPMENT UNDER THE INFLUENCE OF HIGH SSTS AND
INCREASED VWS. 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 NORTHEASTWARD ALONG THE NORTHWESTERN
PERIPHERY OF A MID-LEVEL SUB-TROPICAL HIGH. ANIMATED MSI SHOWS CB
CLUSTERS ARE SCATTERED AROUND THE CSC.
3.TRACK FORECAST
THE SYSTEM WILL MOVE NORTHEASTWARD ALONG THE PERIPHERY OF A
MID-LEVEL SUB-TROPICAL HIGH UNTIL FT12. THE SYSTEM WILL THEN MOVE
EAST-NORTHEASTWARD 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 FT24 DUE TO THE INFLUENCE OF
INCREASED VWS. THE SYSTEM WILL TRANSFORM INTO AN EXTRATROPICAL
CYCLONE BY FT12. THE INTENSITY FORECAST IS BASED ON A CONSENSUS OF
GUIDANCE DATA INCLUDING GSM.

1.GENERAL COMMENTS
TS CHOI-WAN IS LOCATED AT 23.0N, 122.4E. INFORMATION ON THE
CURRENT POSITION IS BASED ON ANIMATED MSI AND SURFACE
OBSERVATIONS. POSITIONAL ACCURACY IS FAIR. CENTRAL PRESSURE IS
1002HPA AND MAXIMUM SUSTAINED WINDS ARE 35KNOTS. THE SYSTEM IS IN
A NEUTRAL ENVIRONMENT FOR DEVELOPMENT UNDER THE INFLUENCE OF HIGH
SSTS, DRY AIR AND LAND. 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 NORTHEASTWARD ALONG THE NORTHWESTERN
PERIPHERY OF A MID-LEVEL SUB-TROPICAL HIGH. ANIMATED MSI SHOWS THE
SEPARATION OF ACTIVE CONVECTIVE CLOUD CLUSTERS FROM THE CSC.
3.TRACK FORECAST
THE SYSTEM WILL MOVE NORTHEASTWARD ALONG THE PERIPHERY OF A
MID-LEVEL SUB-TROPICAL HIGH UNTIL FT12. THE SYSTEM WILL THEN MOVE
EAST-NORTHEASTWARD 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, DRY AIR AND INCREASED
VWS. THE SYSTEM WILL THEN GRADUALLY DEVELOP UNTIL FT24 IN A STATE
OF EXTRATROPICAL TRANSITION. THE INTENSITY FORECAST IS BASED ON
GUIDANCE DATA.

REASONING NO.22 FOR TS 2103 CHOI-WAN (2103)
1.GENERAL COMMENTS
TS CHOI-WAN IS LOCATED AT 20.9N, 119.5E. INFORMATION ON THE
CURRENT POSITION IS BASED ON ANIMATED MSI. POSITIONAL ACCURACY IS
FAIR. CENTRAL PRESSURE IS 1002HPA AND MAXIMUM SUSTAINED WINDS NEAR
THE CENTER ARE 35KNOTS. THE SYSTEM IS IN A NEUTRAL ENVIRONMENT FOR
DEVELOPMENT UNDER THE INFLUENCE OF HIGH SSTS, STRONG 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 NORTHEASTWARD ALONG THE NORTHWESTERN
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 IN THE DIRECTION OF THE MOVEMENT.
3.TRACK FORECAST
THE SYSTEM WILL GRADUALLY ACCELERATE AND MOVE NORTHEASTWARD ALONG
THE PERIPHERY OF A MID-LEVEL SUB-TROPICAL HIGH UNTIL FT24. THE
SYSTEM WILL THEN MOVE EAST-NORTHEASTWARD 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 HIGH SSTS. THE SYSTEM WILL THEN WEAKEN UNTIL FT48 IN
A STATE OF EXTRATROPICAL TRANSITION. THE SYSTEM WILL TRANSFORM
INTO AN EXTRATROPICAL CYCLONE BY FT48. THE INTENSITY FORECAST IS
BASED ON A CONSENSUS OF GUIDANCE DATA INCLUDING GSM.

RSMC TROPICAL CYCLONE PROGNOSTIC REASONING
REASONING NO.20 FOR TS 2103 CHOI-WAN (2103)
1.GENERAL COMMENTS
TS CHOI-WAN IS LOCATED AT 19.5N, 118.4E. INFORMATION ON THE
CURRENT POSITION IS BASED ON ANIMATED MSI AND SURFACE
OBSERVATIONS. POSITIONAL ACCURACY IS FAIR. CENTRAL PRESSURE IS
1002HPA AND MAXIMUM SUSTAINED WINDS ARE 35KNOTS. THE SYSTEM IS IN
AN UNFAVORABLE ENVIRONMENT FOR DEVELOPMENT UNDER THE INFLUENCE OF
STRONG VWS 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.
2.SYNOPTIC SITUATION
THE SYSTEM IS MOVING NORTHWARD ALONG THE SOUTHWESTERN PERIPHERY OF
A MID-LEVEL SUB-TROPICAL HIGH. ANIMATED MSI SHOWS THE SEPARATION
OF ACTIVE CONVECTIVE CLOUD CLUSTERS FROM THE CSC. 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-NORTHEASTWARD ALONG THE PERIPHERY OF A
MID-LEVEL SUB-TROPICAL HIGH UNTIL FT12. THE SYSTEM WILL THEN MOVE
NORTHEASTWARD 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, STRONG VWS AND DRY AIR.
THE SYSTEM WILL THEN GRADUALLY WEAKEN UNTIL FT24 DUE TO THE
INFLUENCE OF INTERACTION WITH STRONG VWS AND DRY AIR. THE
INTENSITY FORECAST IS BASED ON GUIDANCE DATA.

RSMC TROPICAL CYCLONE PROGNOSTIC REASONING
REASONING NO.19 FOR TS 2103 CHOI-WAN (2103)
1.GENERAL COMMENTS
TS CHOI-WAN IS LOCATED AT 18.5N, 118.2E. INFORMATION ON THE
CURRENT POSITION IS BASED ON ANIMATED MSI AND SURFACE
OBSERVATIONS. POSITIONAL ACCURACY IS FAIR. CENTRAL PRESSURE IS
1000HPA AND MAXIMUM SUSTAINED WINDS ARE 40KNOTS. THE SYSTEM IS IN
A NEUTRAL ENVIRONMENT FOR DEVELOPMENT UNDER THE INFLUENCE OF HIGH
SSTS 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 GATHERING AROUND THE CSC. WATER VAPOR IMAGERY SHOWS DRY
AIR IN THE DIRECTION OF THE MOVEMENT. DMSP-F15/SSMI 89 GHZ
MICROWAVE IMAGERY SHOWS THE SYSTEM HAS ACTIVE CONVECTIVE CLOUD
CLUSTERS AROUND THE CSC.
3.TRACK FORECAST
THE SYSTEM WILL MOVE NORTH-NORTHEASTWARD ALONG THE PERIPHERY OF A
MID-LEVEL SUB-TROPICAL HIGH UNTIL FT12. THE SYSTEM WILL THEN MOVE
NORTHEASTWARD 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 GRADUALLY WEAKEN UNTIL FT12 DUE TO THE INFLUENCE
OF DRY AIR. THE SYSTEM WILL THEN GRADUALLY WEAKEN UNTIL FT24 DUE
TO THE INFLUENCE OF INTERACTION WITH STRONG VWS AND DRY AIR. THE
SYSTEM WILL WEAKEN TO TD INTENSITY BY FT24. THE INTENSITY FORECAST
IS BASED ON A CONSENSUS OF GUIDANCE DATA INCLUDING GSM.

NORTHEASTWARD ALONG THE PERIPHERY OF A MID-LEVEL SUB-TROPICAL HIGH
UNTIL FT24. THE TRACK FORECAST IS BASED ON GSM PREDICTIONS, AND

RSMC TROPICAL CYCLONE PROGNOSTIC REASONING
REASONING NO.17 FOR TS 2103 CHOI-WAN (2103)
1.GENERAL COMMENTS
TS CHOI-WAN IS LOCATED AT 16.7N, 118.9E. INFORMATION ON THE
CURRENT POSITION IS BASED ON ANIMATED MSI. POSITIONAL ACCURACY IS
FAIR. CENTRAL PRESSURE IS 1002HPA AND MAXIMUM SUSTAINED WINDS NEAR
THE CENTER ARE 35KNOTS. THE SYSTEM IS IN A NEUTRAL ENVIRONMENT FOR
DEVELOPMENT UNDER THE INFLUENCE OF HIGH SSTS, HIGH TCHP AND LAND.
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. 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 NORTHWARD ALONG THE PERIPHERY OF A MID-LEVEL
SUB-TROPICAL HIGH UNTIL FT12. THE SYSTEM WILL THEN MOVE
NORTH-NORTHEASTWARD 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 LOW DUE TO SIGNIFICANT DIFFERENCES AMONG NWP MODEL
OUTPUTS.
4.INTENSITY FORECAST
THE SYSTEM WILL MAINTAIN ITS INTENSITY UNTIL FT12 DUE TO THE
INFLUENCE OF INTERACTION WITH HIGH SSTS AND HIGH TCHP. THE SYSTEM
WILL THEN GRADUALLY WEAKEN UNTIL FT24 DUE TO THE INFLUENCE OF
INTERACTION WITH DRY AIR AND INCREASED VWS. THE SYSTEM WILL WEAKEN
TO TD INTENSITY BY FT24. THE INTENSITY FORECAST IS BASED ON A
CONSENSUS OF GUIDANCE DATA INCLUDING GSM.

REASONING NO.16 FOR TS 2103 CHOI-WAN (2103)
1.GENERAL COMMENTS
TS CHOI-WAN IS LOCATED AT 14.6N, 119.7E. INFORMATION ON THE
CURRENT POSITION IS BASED ON ANIMATED MSI AND SURFACE
OBSERVATIONS. POSITIONAL ACCURACY IS FAIR. CENTRAL PRESSURE IS
1002HPA AND MAXIMUM SUSTAINED WINDS NEAR THE CENTER ARE 35KNOTS.
THE SYSTEM IS IN A NEUTRAL ENVIRONMENT FOR DEVELOPMENT UNDER THE
INFLUENCE OF HIGH SSTS, HIGH 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. ANIMATED MSI SHOWS GOOD CLOUD
CHARACTERISTICS OF ANTICYCLONIC OUTFLOW. WATER VAPOR IMAGERY SHOWS
DRY AIR IN THE DIRECTION OF THE MOVEMENT.
3.TRACK FORECAST
THE SYSTEM WILL GRADUALLY TURN TO THE NORTH 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 LOW DUE TO SIGNIFICANT DIFFERENCES AMONG
NWP MODEL OUTPUTS.
4.INTENSITY FORECAST
THE SYSTEM WILL MAINTAIN ITS INTENSITY UNTIL FT12 DUE TO THE
INFLUENCE OF INTERACTION WITH HIGH SSTS, HIGH TCHP AND DRY AIR.
THE SYSTEM WILL THEN WEAKEN UNTIL FT24 DUE TO THE INFLUENCE OF
INTERACTION WITH DRY AIR AND INCREASED VWS. THE SYSTEM WILL WEAKEN
TO TD INTENSITY BY FT24. THE INTENSITY FORECAST IS BASED ON A
CONSENSUS OF GUIDANCE DATA INCLUDING GSM.

GATHERING AROUND THE CSC. ANIMATED MSI SHOWS THE CLOUD
CHARACTERISTICS OF ANTICYCLONIC OUTFLOW ARE NOW DISTINCT. WATER
VAPOR IMAGERY SHOWS DRY AIR AROUND THE SYSTEM.
3.TRACK FORECAST
THE SYSTEM WILL GRADUALLY TURN TO THE NORTH 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 LOW DUE TO SIGNIFICANT DIFFERENCES AMONG
NWP MODEL OUTPUTS.
4.INTENSITY FORECAST
THE SYSTEM WILL MAINTAIN ITS INTENSITY UNTIL FT12 DUE TO THE
INFLUENCE OF INTERACTION WITH HIGH SSTS, HIGH TCHP, DRY AIR AND
LAND. THE SYSTEM WILL THEN WEAKEN UNTIL FT24 DUE TO THE INFLUENCE
OF INTERACTION WITH DRY AIR AND INCREASED VWS. 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.14 FOR TS 2103 CHOI-WAN (2103)
1.GENERAL COMMENTS
TS CHOI-WAN IS LOCATED AT 13.4N, 121.6E. INFORMATION ON THE
CURRENT POSITION IS BASED ON ANIMATED MSI AND SURFACE
OBSERVATIONS. POSITIONAL ACCURACY IS FAIR. CENTRAL PRESSURE IS
1002HPA AND MAXIMUM SUSTAINED WINDS ARE 35KNOTS. THE SYSTEM IS IN
A NEUTRAL ENVIRONMENT FOR DEVELOPMENT UNDER THE INFLUENCE OF HIGH
SSTS, GOOD UPPER-LEVEL OUTFLOW, DRY AIR AND LAND. 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. 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 FT12. THE SYSTEM WILL THEN MOVE
NORTHWARD 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, GOOD UPPER LEVEL OUTFLOW,
DRY AIR AND LAND. THE SYSTEM WILL THEN WEAKEN UNTIL FT24 DUE TO
THE INFLUENCE OF INTERACTION WITH DRY AIR AND LAND. THE INTENSITY
FORECAST IS BASED ON GUIDANCE DATA.

REASONING NO.13 FOR TS 2103 CHOI-WAN (2103)
1.GENERAL COMMENTS
TS CHOI-WAN IS LOCATED AT 12.3N, 122.3E. INFORMATION ON THE
CURRENT POSITION IS BASED ON ANIMATED MSI AND SURFACE
OBSERVATIONS. POSITIONAL ACCURACY IS FAIR. CENTRAL PRESSURE IS
1002HPA AND MAXIMUM SUSTAINED WINDS ARE 35KNOTS. THE SYSTEM IS IN
A NEUTRAL ENVIRONMENT FOR DEVELOPMENT. 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 WEST-NORTHWESTWARD ALONG THE SOUTHERN
PERIPHERY OF A MID-LEVEL SUB-TROPICAL HIGH. ANIMATED MSI SHOWS THE
SEPARATION OF ACTIVE CONVECTIVE CLOUD CLUSTERS FROM THE CSC.
DMSP-F17/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 FT12. THE SYSTEM WILL THEN 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 HIGH SSTS AND LAND. THE SYSTEM WILL
THEN WEAKEN UNTIL FT24 DUE TO THE INFLUENCE OF LAND. THE SYSTEM
WILL WEAKEN TO TD INTENSITY BY FT24. THE INTENSITY FORECAST IS
BASED ON GUIDANCE DATA.

RSMC TROPICAL CYCLONE PROGNOSTIC REASONING
REASONING NO.11 FOR TS 2103 CHOI-WAN (2103)
1.GENERAL COMMENTS
TS CHOI-WAN IS LOCATED AT 11.7N, 125.6E. INFORMATION ON THE
CURRENT POSITION IS BASED ON ANIMATED MSI AND SURFACE
OBSERVATIONS. POSITIONAL ACCURACY IS FAIR. CENTRAL PRESSURE IS
1000HPA AND MAXIMUM SUSTAINED WINDS NEAR THE CENTER ARE 35KNOTS.
THE SYSTEM IS IN A NEUTRAL ENVIRONMENT FOR DEVELOPMENT UNDER THE
INFLUENCE OF HIGH SSTS AND INCREASED VWS. 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. WATER
VAPOR IMAGERY SHOWS DRY AIR IN THE DIRECTION OF THE MOVEMENT.
3.TRACK FORECAST
THE SYSTEM WILL MOVE NORTHWESTWARD ALONG THE PERIPHERY OF A
MID-LEVEL SUB-TROPICAL HIGH UNTIL FT24. THE SYSTEM WILL THEN MOVE
NORTHWARD UNTIL FT48. THE TRACK FORECAST IS BASED ON GSM
PREDICTIONS, AND REFERENCE TO OTHER NWP MODELS. TRACK FORECAST
CONFIDENCE IS LOW DUE TO SIGNIFICANT DIFFERENCES AMONG NWP MODEL
OUTPUTS.
4.INTENSITY FORECAST
THE SYSTEM WILL MAINTAIN ITS INTENSITY UNTIL FT24 DUE TO THE
INFLUENCE OF INTERACTION WITH HIGH SSTS AND LAND. THE SYSTEM WILL
THEN WEAKEN UNTIL FT48 DUE TO THE INFLUENCE OF INTERACTION WITH
DRY AIR AND LAND. THE SYSTEM WILL WEAKEN TO TD INTENSITY BY FT48.
THE INTENSITY FORECAST IS BASED ON A CONSENSUS OF GUIDANCE DATA
INCLUDING GSM.

REASONING NO.10 FOR TS 2103 CHOI-WAN (2103)
1.GENERAL COMMENTS
TS CHOI-WAN IS LOCATED AT 11.1N, 126.8E. INFORMATION ON THE
CURRENT POSITION IS BASED ON ANIMATED MSI AND SURFACE
OBSERVATIONS. POSITIONAL ACCURACY IS FAIR. CENTRAL PRESSURE IS
1000HPA AND MAXIMUM SUSTAINED WINDS NEAR THE CENTER ARE 35KNOTS.
THE SYSTEM IS IN AN UNFAVORABLE ENVIRONMENT FOR DEVELOPMENT UNDER
THE INFLUENCE OF INCREASED VWS 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 IN THE DIRECTION OF THE MOVEMENT.
3.TRACK FORECAST
THE SYSTEM WILL MOVE NORTHWESTWARD ALONG THE PERIPHERY OF A
MID-LEVEL SUB-TROPICAL HIGH UNTIL FT24. THE SYSTEM WILL THEN
GRADUALLY TURN TO THE NORTH-NORTHWEST UNTIL FT48. THE SYSTEM WILL
HIT THE PHILIPPINES BY FT48. THE TRACK FORECAST IS BASED ON GSM
PREDICTIONS, AND REFERENCE TO OTHER NWP MODELS. TRACK FORECAST
CONFIDENCE IS LOW DUE TO SIGNIFICANT DIFFERENCES AMONG NWP MODEL
OUTPUTS.
4.INTENSITY FORECAST
THE SYSTEM WILL MAINTAIN ITS INTENSITY UNTIL FT24 DUE TO THE
INFLUENCE OF INTERACTION WITH HIGH SSTS AND HIGH TCHP. THE SYSTEM
WILL THEN WEAKEN UNTIL FT48 DUE TO THE INFLUENCE OF INTERACTION
WITH DRY AIR AND LAND. THE SYSTEM WILL WEAKEN TO TD INTENSITY BY
FT48. THE INTENSITY FORECAST IS BASED ON A CONSENSUS OF GUIDANCE
DATA INCLUDING GSM.

THE SYSTEM IS MOVING WESTWARD 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 IN THE DIRECTION OF THE MOVEMENT. DMSP-F17/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 SYSTEM WILL THEN
GRADUALLY TURN TO THE NORTH UNTIL FT72. THE TRACK FORECAST IS
BASED ON GSM PREDICTIONS, AND REFERENCE TO OTHER NWP MODELS. TRACK
FORECAST CONFIDENCE IS LOW DUE TO SIGNIFICANT DIFFERENCES AMONG
NWP MODEL OUTPUTS.
4.INTENSITY FORECAST
THE SYSTEM WILL MAINTAIN ITS INTENSITY UNTIL FT24 DUE TO THE
INFLUENCE OF INTERACTION WITH HIGH SSTS AND HIGH TCHP. THE SYSTEM
WILL THEN GRADUALLY WEAKEN UNTIL FT72 DUE TO THE INFLUENCE OF
INTERACTION WITH DRY AIR AND LAND. THE SYSTEM WILL WEAKEN TO TD
INTENSITY BY FT72. THE INTENSITY FORECAST IS BASED ON A CONSENSUS
OF GUIDANCE DATA INCLUDING GSM.

Original Message :

WTPQ30 RJTD 311800
RSMC TROPICAL CYCLONE PROGNOSTIC REASONING
REASONING NO. 8 FOR TS 2103 CHOI-WAN (2103)
1.GENERAL COMMENTS
TS CHOI-WAN IS LOCATED AT 9.7N, 128.5E. INFORMATION ON THE CURRENT
POSITION IS BASED ON ANIMATED MSI. POSITIONAL ACCURACY IS FAIR.
CENTRAL PRESSURE IS 998HPA AND MAXIMUM SUSTAINED WINDS NEAR THE
CENTER ARE 40KNOTS. THE SYSTEM IS IN A FAVORABLE ENVIRONMENT FOR
DEVELOPMENT UNDER THE INFLUENCE OF HIGH SSTS. 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 WINDS DATA ESTIMATED FROM SATELLITE SCATTEROMETERS.
2.SYNOPTIC SITUATION
THE SYSTEM IS MOVING WEST-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 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 NORTHWESTWARD ALONG THE PERIPHERY OF A
MID-LEVEL SUB-TROPICAL HIGH UNTIL FT48. THE SYSTEM WILL THEN MOVE
NORTHWARD UNTIL FT72. 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 HIGH SSTS. THE SYSTEM WILL THEN GRADUALLY WEAKEN
UNTIL FT72 DUE TO THE INFLUENCE OF DRY AIR. THE SYSTEM WILL WEAKEN
TO TD INTENSITY BY FT72. THE INTENSITY FORECAST IS BASED ON A
CONSENSUS OF GUIDANCE DATA INCLUDING GSM.

WTPQ30 RJTD 311200
RSMC TROPICAL CYCLONE PROGNOSTIC REASONING
REASONING NO. 7 FOR TS 2103 CHOI-WAN (2103)
1.GENERAL COMMENTS
TS CHOI-WAN IS LOCATED AT 9.5N, 129.1E. INFORMATION ON THE CURRENT
POSITION IS BASED ON ANIMATED MSI. POSITIONAL ACCURACY IS FAIR.
CENTRAL PRESSURE IS 1000HPA AND MAXIMUM SUSTAINED WINDS NEAR THE
CENTER ARE 35KNOTS. THE SYSTEM IS IN A FAVORABLE ENVIRONMENT FOR
DEVELOPMENT UNDER THE INFLUENCE OF HIGH SSTS. HOWEVER, THE LIMITED
FIRMNESS OF ITS STRUCTURE HAS CAUSED IT 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 WEST-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 IN THE DIRECTION OF THE MOVEMENT.
3.TRACK FORECAST
THE SYSTEM WILL MOVE NORTHWESTWARD ALONG THE PERIPHERY OF A
MID-LEVEL SUB-TROPICAL HIGH UNTIL FT48. THE SYSTEM WILL THEN MOVE
NORTH-NORTHWESTWARD UNTIL FT72. THE TRACK FORECAST IS BASED ON GSM
PREDICTIONS, AND REFERENCE TO OTHER NWP MODELS. TRACK FORECAST
CONFIDENCE IS FAIR UNTIL FT48 BUT LOW THEREAFTER DUE TO
SIGNIFICANT DIFFERENCES AMONG NWP MODEL OUTPUTS.
4.INTENSITY FORECAST
THE SYSTEM WILL DEVELOP UNTIL FT24 DUE TO THE INFLUENCE OF HIGH
SSTS. THE SYSTEM WILL THEN MAINTAIN ITS INTENSITY UNTIL FT48. THE
SYSTEM WILL THEN WEAKEN UNTIL FT72 DUE TO THE INFLUENCE OF DRY
AIR. THE SYSTEM WILL WEAKEN TO TD INTENSITY BY FT72. THE INTENSITY
FORECAST IS BASED ON A CONSENSUS OF GUIDANCE DATA INCLUDING GSM.

WTPQ30 RJTD 310600
RSMC TROPICAL CYCLONE PROGNOSTIC REASONING
REASONING NO. 6 FOR TS 2103 CHOI-WAN (2103)
1.GENERAL COMMENTS
TS CHOI-WAN IS LOCATED AT 9.4N, 129.9E. INFORMATION ON THE CURRENT
POSITION IS BASED ON ANIMATED MSI AND SURFACE OBSERVATIONS.
POSITIONAL ACCURACY IS FAIR. CENTRAL PRESSURE IS 1000HPA 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. HOWEVER, THE LIMITED FIRMNESS OF ITS
STRUCTURE HAS CAUSED IT TO MAINTAIN ITS INTENSITY OVER THE LAST
SIX HOURS. INFORMATION ON THE CURRENT INTENSITY IS BASED ON DVORAK
INTENSITY ANALYSES AND SURFACE WINDS DATA ESTIMATED FROM SEA
SURFACE AMVS.
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.
3.TRACK FORECAST
THE SYSTEM WILL MOVE NORTHWESTWARD ALONG THE PERIPHERY OF A
MID-LEVEL SUB-TROPICAL HIGH UNTIL FT72. THE SYSTEM WILL THEN MOVE
NORTHWARD UNTIL FT96. THE TRACK FORECAST IS BASED ON GSM
PREDICTIONS, AND REFERENCE TO OTHER NWP MODELS. TRACK FORECAST
CONFIDENCE IS LOW DUE TO SIGNIFICANT DIFFERENCES AMONG NWP MODEL
OUTPUTS.
4.INTENSITY FORECAST
THE SYSTEM WILL DEVELOP UNTIL FT24 DUE TO THE INFLUENCE OF
INTERACTION WITH HIGH SSTS AND HIGH TCHP. THE SYSTEM WILL THEN
MAINTAIN ITS INTENSITY UNTIL FT48 DUE TO THE INFLUENCE OF
INTERACTION WITH HIGH SSTS, HIGH TCHP AND DRY AIR. THE SYSTEM WILL
THEN WEAKEN UNTIL FT96 DUE TO THE INFLUENCE OF DRY AIR. THE
INTENSITY FORECAST IS BASED ON A CONSENSUS OF GUIDANCE DATA
INCLUDING GSM.

RSMC TROPICAL CYCLONE PROGNOSTIC REASONING
REASONING NO. 5 FOR TS 2103 CHOI-WAN (2103)
1.GENERAL COMMENTS
A TD PREVIOUSLY LOCATED AT 6.5N, 131.6E HAS BEEN UPGRADED TO TS
(CHOI-WAN) STATUS. TS CHOI-WAN IS LOCATED AT 8.3N, 131.3E.
INFORMATION ON THE CURRENT POSITION IS BASED ON ANIMATED MSI AND
SURFACE OBSERVATIONS. POSITIONAL ACCURACY IS FAIR. CENTRAL
PRESSURE IS 1000HPA 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 WINDS DATA ESTIMATED FROM SATELLITE
SCATTEROMETERS.
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. ANIMATED MSI SHOWS
GOOD CLOUD CHARACTERISTICS OF ANTICYCLONIC OUTFLOW. WATER VAPOR
IMAGERY SHOWS DRY AIR IN THE DIRECTION OF THE MOVEMENT.
3.TRACK FORECAST
THE SYSTEM WILL MOVE NORTHWESTWARD ALONG THE PERIPHERY OF A
MID-LEVEL SUB-TROPICAL HIGH UNTIL FT72. THE SYSTEM WILL THEN MOVE
NORTHWARD UNTIL FT96. THE TRACK FORECAST IS BASED ON GSM
PREDICTIONS, AND REFERENCE TO OTHER NWP MODELS. TRACK FORECAST
CONFIDENCE IS FAIR UNTIL FT96 BUT LOW THEREAFTER DUE TO
SIGNIFICANT DIFFERENCES AMONG NWP MODEL OUTPUTS.
4.INTENSITY FORECAST
THE SYSTEM WILL DEVELOP UNTIL FT48 DUE TO THE INFLUENCE OF
INTERACTION WITH HIGH SSTS AND HIGH TCHP. THE SYSTEM WILL THEN
MAINTAIN ITS INTENSITY UNTIL FT72 DUE TO THE INFLUENCE OF
INTERACTION WITH HIGH SSTS, HIGH TCHP AND INCREASED VWS. THE
SYSTEM WILL THEN WEAKEN UNTIL FT96 DUE TO THE INFLUENCE OF
INTERACTION WITH INCREASED VWS AND DRY AIR. THE SYSTEM WILL WEAKEN
TO TD INTENSITY BY FT96. THE INTENSITY FORECAST IS BASED ON A
CONSENSUS OF GUIDANCE DATA INCLUDING GSM.
