WTPQ30 RJTD 280000 CCA
RSMC TROPICAL CYCLONE PROGNOSTIC REASONING
REASONING NO.17 FOR STS 2527 KOTO (2527)
1.GENERAL COMMENTS
STS KOTO IS LOCATED AT 12.4N, 113.1E. INFORMATION ON THE CURRENT
POSITION IS BASED ON ANIMATED MSI AND SURFACE OBSERVATIONS.
POSITIONAL ACCURACY IS GOOD. CENTRAL PRESSURE IS 985HPA AND
MAXIMUM SUSTAINED WINDS NEAR THE CENTER ARE 55KNOTS. THE SYSTEM IS
IN AN UNFAVORABLE ENVIRONMENT FOR DEVELOPMENT UNDER THE INFLUENCE
OF LOWER SSTS, REDUCED TCHP 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 SLOWLY SOUTH-SOUTHEASTWARD DUE TO WEAK
STEERING FLOW. ANIMATED MSI SHOWS THE SEPARATION OF ACTIVE
CONVECTIVE CLOUD CLUSTERS FROM THE CSC. DMSP-F17/SSMIS 89 GHZ
MICROWAVE IMAGERY SHOWS THE SYSTEM HAS A BAND WITH CURVATURE
INDICATING THE CSC.
3.TRACK FORECAST
THE SYSTEM WILL REMAIN ALMOST STATIONARY DUE TO WEAK STEERING FLOW
UNTIL FT72. THE SYSTEM WILL THEN MOVE WESTWARD ALONG THE PERIPHERY
OF A MID-LEVEL SUB-TROPICAL HIGH UNTIL FT120. THE SYSTEM WILL HIT
VIET-NAM BY FT120. 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 FT96 DUE TO ITS PRESENCE
OVER THE SAME WATERS. THE SYSTEM WILL THEN WEAKEN UNTIL FT120 DUE
TO ITS LANDFALL. THE SYSTEM WILL WEAKEN TO TD INTENSITY BY FT120.
THE INTENSITY FORECAST IS BASED ON A CONSENSUS OF GUIDANCE DATA
INCLUDING GSM.
