RSMC TROPICAL CYCLONE PROGNOSTIC REASONING
REASONING NO.45 FOR TY 2519 NEOGURI (2519)
1.GENERAL COMMENTS
  TY NEOGURI IS LOCATED AT 40.4N, 169.8E. INFORMATION ON THE CURRENT
  POSITION IS BASED ON THE EYE IN ANIMATED MSI AND SURFACE
  OBSERVATIONS. POSITIONAL ACCURACY IS GOOD. CENTRAL PRESSURE IS
  960HPA AND MAXIMUM SUSTAINED WINDS NEAR THE CENTER ARE 80KNOTS.
  THE SYSTEM IS IN AN UNFAVORABLE ENVIRONMENT FOR DEVELOPMENT UNDER
  THE INFLUENCE OF LOWER SSTS, LOW 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 WINDS DATA ESTIMATED FROM SATELLITE SCATTEROMETERS.
2.SYNOPTIC SITUATION
  THE SYSTEM IS MOVING NORTHEASTWARD DUE TO INTERACTION WITH A
  MID-LATITUDE TROUGH. ANIMATED MSI SHOWS THE SYSTEM HAS AN EYE.
  ANIMATED MSI SHOWS GOOD CLOUD CHARACTERISTICS OF ANTICYCLONIC
  OUTFLOW. GCOM-W/AMSR2 89 GHZ MICROWAVE IMAGERY SHOWS THE SYSTEM
  HAS AN EYE.
3.TRACK FORECAST
  THE SYSTEM WILL MOVE NORTHEASTWARD UNDER THE INFLUENCE OF A
  MID-LATITUDE TROUGH UNTIL FT12. THE SYSTEM WILL THEN GRADUALLY
  TURN TO THE EAST-NORTHEAST 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 WEAKEN UNTIL FT24 DUE TO THE INFLUENCE OF
  INTERACTION WITH LOW SSTS, LOW TCHP AND STRONG VWS. THE SYSTEM
  WILL TRANSFORM INTO AN EXTRATROPICAL CYCLONE BY FT06. THE
  INTENSITY FORECAST IS BASED ON A CONSENSUS OF GUIDANCE DATA
  INCLUDING GSM.
