RSMC TROPICAL CYCLONE PROGNOSTIC REASONING
REASONING NO. 2 FOR TS 1822 MANGKHUT (1822)
1.GENERAL COMMENTS
A TD PREVIOUSLY LOCATED AT 12.2N, 166.3E HAS BEEN UPGRADED TO TS
(MANGKHUT) STATUS. TS MANGKHUT IS LOCATED AT 12.9N, 165.3E.
INFORMATION ON THE CURRENT POSITION IS BASED ON ANIMATED MSI.
POSITIONAL ACCURACY IS FAIR. 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 CURRENT INTENSITY IS BASED ON DVORAK INTENSITY
ANALYSES.
2.SYNOPTIC SITUATION
THE SYSTEM IS MOVING NORTHWESTWARD 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.
ANIMATED MSI SHOWS GOOD CLOUD CHARACTERISTICS OF ANTICYCLONIC
OUTFLOW. 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 WEST-NORTHWESTWARD ALONG THE PERIPHERY OF A
MID-LEVEL SUB-TROPICAL HIGH UNTIL FT12. THE SYSTEM WILL THEN MOVE
WESTWARD UNTIL FT72. THE SYSTEM WILL THEN GRADUALLY DECELERATE AND
MOVE WESTWARD UNTIL FT96. THE SYSTEM WILL THEN MOVE
WEST-NORTHWESTWARD UNTIL FT120. THE JMA TRACK FORECAST IS BASED ON
GSM PREDICTIONS. JMA TRACK FORECAST CONFIDENCE IS FAIR UNTIL FT24
BUT LOW THEREAFTER DUE TO SIGNIFICANT DIFFERENCES AMONG NUMERICAL
MODEL OUTPUTS.
4.INTENSITY FORECAST
THE SYSTEM WILL DEVELOP UNTIL FT72 DUE TO THE INFLUENCE OF
INTERACTION WITH HIGH SSTS, HIGH TCHP, WEAK VWS AND GOOD UPPER
LEVEL OUTFLOW. THE JMA INTENSITY FORECAST IS BASED ON GSM
PREDICTIONS. =
