REASONING NO.26 FOR EXTRATROPICAL CYCLONE LOCATED AT 35N 162E
1.GENERAL COMMENTS
HALONG (2522) HAS TRANSFORMED INTO AN EXTRATROPICAL CYCLONE. THE
EXTRATROPICAL CYCLONE IS LOCATED AT 35N, 162E. INFORMATION ON THE
CURRENT POSITION IS BASED ON ANIMATED MSI AND SURFACE
OBSERVATIONS. CENTRAL PRESSURE IS 980HPA AND MAXIMUM SUSTAINED
WINDS ARE 60KNOTS. INFORMATION ON THE CURRENT INTENSITY IS BASED
ON DVORAK INTENSITY ANALYSES AND SURFACE OBSERVATIONS.
2.SYNOPTIC SITUATION
THE SYSTEM IS MOVING EASTWARD ALONG THE NORTHERN PERIPHERY OF A
MID-LEVEL SUB-TROPICAL HIGH. ANIMATED MSI SHOWS THE SEPARATION OF
ACTIVE CONVECTIVE CLOUD CLUSTERS FROM THE CSC. METOP-C/MHS 85 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.

REASONING NO.25 FOR STS 2522 HALONG (2522)
1.GENERAL COMMENTS
STS HALONG IS LOCATED AT 34.6N, 158.8E. INFORMATION ON THE CURRENT
POSITION IS BASED ON ANIMATED MSI AND SURFACE OBSERVATIONS.
POSITIONAL ACCURACY IS FAIR. CENTRAL PRESSURE IS 975HPA AND
MAXIMUM SUSTAINED WINDS NEAR THE CENTER ARE 60KNOTS. 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 DVORAK INTENSITY ANALYSES AND SURFACE
OBSERVATIONS.
2.SYNOPTIC SITUATION
THE SYSTEM IS MOVING EASTWARD UNDER THE INFLUENCE OF MID-LATITUDE
PREVAILING WESTERLIES. ANIMATED MSI SHOWS THE SYSTEM HAS A BAND
WITH A CURVATURE SUGGESTING THE CSC. WATER VAPOR IMAGERY SHOWS DRY
AIR AROUND THE SYSTEM. GPM/GMI 89 GHZ MICROWAVE IMAGERY SHOWS THE
SYSTEM HAS A BAND WITH CURVATURE INDICATING THE CSC.
3.TRACK FORECAST
THE SYSTEM WILL GRADUALLY ACCELERATE AND MOVE EAST-NORTHEASTWARD
UNDER THE INFLUENCE OF MID-LATITUDE PREVAILING WESTERLIES 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 FT24 IN A STATE OF
EXTRATROPICAL TRANSITION. THE SYSTEM WILL TRANSFORM INTO AN
EXTRATROPICAL CYCLONE BY FT12. THE INTENSITY FORECAST IS BASED ON
A CONSENSUS OF GUIDANCE DATA INCLUDING GSM.

RSMC TROPICAL CYCLONE PROGNOSTIC REASONING
REASONING NO.21 FOR TY 2522 HALONG (2522)
1.GENERAL COMMENTS
TY HALONG IS LOCATED AT 33.6N, 143.6E. INFORMATION ON THE CURRENT
POSITION IS BASED ON THE EYE IN ANIMATED MSI AND SURFACE
OBSERVATIONS. POSITIONAL ACCURACY IS GOOD. CENTRAL PRESSURE IS
955HPA AND MAXIMUM SUSTAINED WINDS NEAR THE CENTER ARE 85KNOTS.
THE SYSTEM IS IN AN UNFAVORABLE ENVIRONMENT FOR DEVELOPMENT UNDER
THE INFLUENCE OF LOWER SSTS AND INCREASED VWS. 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 EAST-NORTHEASTWARD ALONG THE NORTHWESTERN
PERIPHERY OF A MID-LEVEL SUB-TROPICAL HIGH. ANIMATED MSI SHOWS THE
SYSTEM HAS AN EYE. ANIMATED MSI SHOWS THE CLOUD CHARACTERISTICS OF
ANTICYCLONIC OUTFLOW ARE NOW DISTINCT. WATER VAPOR IMAGERY SHOWS
DRY AIR AROUND THE SYSTEM. NOAA-20/ATMS 85 GHZ MICROWAVE IMAGERY
SHOWS THE SYSTEM HAS AN EYE.
3.TRACK FORECAST
THE SYSTEM WILL MOVE EASTWARD ALONG THE PERIPHERY OF A MID-LEVEL
SUB-TROPICAL HIGH UNTIL FT24. THE SYSTEM WILL THEN MOVE
EAST-NORTHEASTWARD 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 WEAKEN UNTIL FT24 DUE TO THE INFLUENCE OF
INTERACTION WITH LOWER SSTS, REDUCED TCHP AND INCREASED VWS. THE
SYSTEM WILL THEN WEAKEN UNTIL FT48 DUE TO THE INFLUENCE OF
INTERACTION WITH LOWER SSTS AND REDUCED TCHP. THE SYSTEM WILL
TRANSFORM INTO AN EXTRATROPICAL CYCLONE BY FT48. THE INTENSITY
FORECAST IS BASED ON A CONSENSUS OF GUIDANCE DATA INCLUDING GSM.
