DISCUSSION
-----------------------------------
  TS LUPIT IS LOCATED AT 33.9N, 132.6E. INFORMATION ON THE CURRENT
  POSITION IS BASED ON ANIMATED MSI AND SURFACE OBSERVATIONS.
  POSITIONAL ACCURACY IS FAIR. CENTRAL PRESSURE IS 985HPA AND
  MAXIMUM SUSTAINED WINDS ARE 45KNOTS. THE SYSTEM IS IN A FAVORABLE
  ENVIRONMENT FOR DEVELOPMENT UNDER THE INFLUENCE OF HIGH SSTS AND
  WEAK VWS. THIS HAS CAUSED THE SYSTEM TO DEVELOP OVER THE LAST SIX
  HOURS. INFORMATION ON THE CURRENT INTENSITY IS BASED ON SURFACE
  OBSERVATIONS AND SURFACE WINDS DATA ESTIMATED FROM SATELLITE
  SCATTEROMETERS.

  THE SYSTEM IS MOVING NORTHEASTWARD DUE TO INTERACTION WITH A
  MID-LATITUDE TROUGH. ANIMATED MSI SHOWS CB CLUSTERS ARE SCATTERED
  AROUND THE CSC. ANIMATED MSI SHOWS GOOD CLOUD CHARACTERISTICS OF
  ANTICYCLONIC OUTFLOW. WATER VAPOR IMAGERY SHOWS DRY AIR AROUND THE
  SYSTEM.

  THE SYSTEM WILL MOVE NORTHEASTWARD UNDER THE INFLUENCE OF A
  MID-LATITUDE TROUGH UNTIL FT48. 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.

  THE SYSTEM WILL DEVELOP UNTIL FT24 IN A STATE OF EXTRATROPICAL
  TRANSITION. THE SYSTEM WILL TRANSFORM INTO AN EXTRATROPICAL
  CYCLONE BY FT12. THE INTENSITY FORECAST IS BASED ON A CONSENSUS OF
  GUIDANCE DATA INCLUDING GSM.
