RSMC TROPICAL CYCLONE PROGNOSTIC REASONING
REASONING NO. 3 FOR TS 1821 JEBI (1821)
1.GENERAL COMMENTS
THE SYSTEM HAS BEEN UPGRADED TO TS (JEBI) STATUS. TS JEBI IS
LOCATED AT 15.4N, 157.0E. INFORMATION ON THE CURRENT POSITION IS
BASED ON ANIMATED MSI AND SURFACE OBSERVATIONS. 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 THE FORMATION OF
A BAND WITH A CURVATURE SUGGESTING 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 MOVE WESTWARD ALONG THE PERIPHERY OF A MID-LEVEL
SUB-TROPICAL HIGH UNTIL FT96. THE SYSTEM WILL THEN MOVE
NORTHWESTWARD UNTIL FT120. THE JMA TRACK FORECAST IS BASED ON GSM
PREDICTIONS. JMA TRACK FORECAST CONFIDENCE IS FAIR BECAUSE ALL
NUMERICAL MODELS ARE IN CLOSE AGREEMENT.
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 GUIDANCE
DATA.
