REASONING NO.13 FOR TS 2016 NANGKA (2016)
1.GENERAL COMMENTS
TS NANGKA IS LOCATED ON LAND AT 20.0N, 106.2E. 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 35KNOTS. THE SYSTEM IS IN
AN UNFAVORABLE ENVIRONMENT FOR DEVELOPMENT UNDER THE INFLUENCE OF
HIGH SSTS, REDUCED TCHP, INCREASED VWS, GOOD UPPER-LEVEL OUTFLOW
AND LAND. 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 WESTWARD ALONG THE SOUTHWESTERN PERIPHERY OF
A MID-LEVEL SUB-TROPICAL HIGH. ANIMATED MSI SHOWS CB CLUSTERS
GATHERING AROUND THE CSC AND FORMING A CURVED BAND. ANIMATED MSI
SHOWS GOOD CLOUD CHARACTERISTICS OF ANTICYCLONIC OUTFLOW. WATER
VAPOR IMAGERY SHOWS DRY AIR AROUND THE SYSTEM. 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 WESTWARD 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 WEAKEN UNTIL FT24 DUE TO ITS CONTINUED PRESENCE
OVER LAND. THE SYSTEM WILL WEAKEN TO TD INTENSITY BY FT12. THE
INTENSITY FORECAST IS BASED ON A CONSENSUS OF GUIDANCE DATA
INCLUDING GSM.

THE SYSTEM WILL MAINTAIN ITS INTENSITY UNTIL FT12 DUE TO THE
INFLUENCE OF INTERACTION WITH HIGH SSTS, HIGH TCHP, INCREASED VWS

POSITIONAL ACCURACY IS FAIR. CENTRAL PRESSURE IS 992HPA AND
MAXIMUM SUSTAINED WINDS NEAR THE CENTER ARE 45KNOTS. THE SYSTEM IS

RSMC TROPICAL CYCLONE PROGNOSTIC REASONING
REASONING NO. 9 FOR TS 2016 NANGKA (2016)
1.GENERAL COMMENTS
TS NANGKA IS LOCATED AT 18.8N, 111.1E. INFORMATION ON THE CURRENT
POSITION IS BASED ON ANIMATED MSI AND SURFACE OBSERVATIONS.
POSITIONAL ACCURACY IS FAIR. CENTRAL PRESSURE IS 992HPA AND
MAXIMUM SUSTAINED WINDS NEAR THE CENTER ARE 45KNOTS. THE SYSTEM IS
IN A FAVORABLE ENVIRONMENT FOR DEVELOPMENT UNDER THE INFLUENCE OF
HIGH SSTS, WEAK VWS AND GOOD UPPER-LEVEL OUTFLOW. 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 WESTWARD ALONG THE SOUTHERN PERIPHERY OF A
MID-LEVEL SUB-TROPICAL HIGH. ANIMATED MSI SHOWS CB CLUSTERS
GATHERING AROUND THE CSC AND FORMING A CURVED BAND. ANIMATED MSI
SHOWS GOOD CLOUD CHARACTERISTICS OF ANTICYCLONIC OUTFLOW.
GCOM-W/AMSR2 89 GHZ MICROWAVE IMAGERY SHOWS THE SYSTEM HAS A BAND
WITH CURVATURE INDICATING THE CSC.
3.TRACK FORECAST
THE SYSTEM WILL MOVE WESTWARD ALONG THE PERIPHERY OF A MID-LEVEL
SUB-TROPICAL HIGH UNTIL FT48. THE SYSTEM WILL HIT VIET-NAM BY
FT36. 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, WEAK VWS AND GOOD UPPER
LEVEL OUTFLOW. THE SYSTEM WILL THEN WEAKEN UNTIL FT48 DUE TO ITS
LANDFALL. THE SYSTEM WILL WEAKEN TO TD INTENSITY BY FT48. THE
INTENSITY FORECAST IS BASED ON A CONSENSUS OF GUIDANCE DATA
INCLUDING GSM.

REASONING NO. 7 FOR TS 2016 NANGKA (2016)
1.GENERAL COMMENTS
TS NANGKA IS LOCATED AT 17.8N, 113.4E. INFORMATION ON THE CURRENT
POSITION IS BASED ON ANIMATED MSI AND SURFACE OBSERVATIONS.
POSITIONAL ACCURACY IS FAIR. CENTRAL PRESSURE IS 996HPA AND
MAXIMUM SUSTAINED WINDS NEAR THE CENTER ARE 40KNOTS. THE SYSTEM IS
IN A FAVORABLE ENVIRONMENT FOR DEVELOPMENT UNDER THE INFLUENCE OF
HIGH SSTS, HIGH TCHP, WEAK VWS AND GOOD UPPER-LEVEL OUTFLOW.
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 WESTWARD ALONG THE SOUTHERN PERIPHERY OF A
MID-LEVEL SUB-TROPICAL HIGH. ANIMATED MSI SHOWS CB CLUSTERS
GATHERING AROUND THE CSC AND STARTING TO FORM A CURVED BAND.
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 WESTWARD ALONG THE PERIPHERY OF A MID-LEVEL
SUB-TROPICAL HIGH UNTIL FT48. THE SYSTEM WILL HIT VIET-NAM BY
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 DEVELOP UNTIL FT12 DUE TO THE INFLUENCE OF
INTERACTION WITH HIGH SSTS, HIGH TCHP, WEAK VWS AND GOOD UPPER
LEVEL OUTFLOW. THE SYSTEM WILL THEN MAINTAIN ITS INTENSITY UNTIL
FT24 DUE TO THE INFLUENCE OF INTERACTION WITH HIGH SSTS, HIGH
TCHP, WEAK VWS AND LAND. THE SYSTEM WILL THEN WEAKEN UNTIL FT48
DUE TO ITS LANDFALL. THE SYSTEM WILL WEAKEN TO TD INTENSITY BY
FT48. THE INTENSITY FORECAST IS BASED ON A CONSENSUS OF GUIDANCE
DATA INCLUDING GSM.

REASONING NO. 5 FOR TS 2016 NANGKA (2016)
1.GENERAL COMMENTS
A TD PREVIOUSLY LOCATED AT 17.3N, 117.1E HAS BEEN UPGRADED TO TS
(NANGKA) STATUS. TS NANGKA IS LOCATED AT 17.6N, 115.7E.
INFORMATION ON THE CURRENT POSITION IS BASED ON ANIMATED MSI AND
SURFACE OBSERVATIONS. POSITIONAL ACCURACY IS FAIR. CENTRAL
PRESSURE IS 998HPA AND MAXIMUM SUSTAINED WINDS NEAR THE CENTER ARE
35KNOTS. THE SYSTEM IS IN A FAVORABLE ENVIRONMENT FOR DEVELOPMENT
UNDER THE INFLUENCE OF HIGH SSTS, HIGH TCHP, WEAK VWS AND GOOD
UPPER-LEVEL OUTFLOW. 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 WESTWARD ALONG THE SOUTHERN PERIPHERY OF A
MID-LEVEL SUB-TROPICAL HIGH. ANIMATED MSI SHOWS CB CLUSTERS
GATHERING AROUND THE CSC AND STARTING TO FORM A CURVED BAND.
3.TRACK FORECAST
THE SYSTEM WILL MOVE WESTWARD ALONG THE PERIPHERY OF A MID-LEVEL
SUB-TROPICAL HIGH UNTIL FT72. THE SYSTEM WILL HIT VIET-NAM BY
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 DEVELOP UNTIL FT24 DUE TO THE INFLUENCE OF
INTERACTION WITH HIGH SSTS, HIGH TCHP AND WEAK VWS. THE SYSTEM
WILL THEN MAINTAIN ITS INTENSITY UNTIL FT48 DUE TO THE INFLUENCE
OF INTERACTION WITH HIGH SSTS, HIGH TCHP, WEAK VWS AND LAND. THE
SYSTEM WILL THEN WEAKEN UNTIL FT72 DUE TO ITS LANDFALL. THE SYSTEM
WILL WEAKEN TO TD INTENSITY BY FT72. THE INTENSITY FORECAST IS
BASED ON GUIDANCE DATA.
