WTPQ32 RJTD 180000
RSMC TROPICAL CYCLONE PROGNOSTIC REASONING
REASONING NO. 2 FOR TD LOCATED AT 23.3N 164.9E
1.GENERAL COMMENTS
  A TD IS LOCATED AT 23.3N, 164.9E. INFORMATION ON THE CURRENT
  POSITION IS BASED ON ANIMATED MSI AND SURFACE OBSERVATIONS.
  POSITIONAL ACCURACY IS POOR BECAUSE THE CSC IS OBSCURE. CENTRAL
  PRESSURE IS 1008HPA AND MAXIMUM SUSTAINED WINDS NEAR THE CENTER
  ARE 30KNOTS. THE SYSTEM IS IN A FAVORABLE ENVIRONMENT FOR
  DEVELOPMENT UNDER THE INFLUENCE OF HIGH SSTS, HIGH TCHP AND WEAK
  VWS. 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. ANIMATED MSI SHOWS THE CLOUD
  CHARACTERISTICS OF ANTICYCLONIC OUTFLOW ARE NOW DISTINCT. WATER
  VAPOR IMAGERY SHOWS DRY AIR AROUND THE SYSTEM. GPM/GMI 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 FT12. THE SYSTEM WILL THEN MOVE
  WEST-NORTHWESTWARD ALONG THE PERIPHERY OF A MID-LEVEL SUB-TROPICAL
  HIGH UNTIL FT72. THE SYSTEM WILL THEN GRADUALLY TURN TO THE
  NORTH-NORTHWEST ALONG THE PERIPHERY OF A MID-LEVEL SUB-TROPICAL
  HIGH UNTIL FT120. 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 MAINTAIN ITS INTENSITY UNTIL FT12 DUE TO ITS
  CURRENT INFIRM STRUCTURE. THE SYSTEM WILL THEN 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 AND HIGH TCHP.
  THE SYSTEM WILL THEN DEVELOP UNTIL FT120 DUE TO THE INFLUENCE OF
  HIGH SSTS. THE SYSTEM WILL BE UPGRADED TO TS INTENSITY BY FT24.
  THE INTENSITY FORECAST IS BASED ON A CONSENSUS OF GUIDANCE DATA
  INCLUDING GSM.
