DISCUSSION
-----------------------------------
  TS MIRINAE IS LOCATED AT 38.5N, 154.5E. INFORMATION ON THE CURRENT
  POSITION IS BASED ON ANIMATED MSI. POSITIONAL ACCURACY IS FAIR.
  CENTRAL PRESSURE IS 980HPA AND MAXIMUM SUSTAINED WINDS NEAR THE
  CENTER ARE 45KNOTS. THE SYSTEM IS IN AN UNFAVORABLE ENVIRONMENT
  FOR DEVELOPMENT UNDER THE INFLUENCE OF LOWER SSTS. HOWEVER, ITS
  STATE OF EXTRATROPICAL TRANSITION 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.

  THE SYSTEM IS MOVING EASTWARD ALONG THE NORTHERN PERIPHERY OF A
  MID-LEVEL SUB-TROPICAL HIGH. ANIMATED MSI SHOWS THE SEPARATION OF
  ACTIVE CONVECTIVE CLOUD CLUSTERS FROM THE CSC.

  THE SYSTEM WILL MOVE EASTWARD ALONG THE PERIPHERY OF A MID-LEVEL
  SUB-TROPICAL HIGH 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.

  THE SYSTEM WILL MAINTAIN ITS INTENSITY UNTIL FT12 IN A STATE OF
  EXTRATROPICAL TRANSITION. THE SYSTEM WILL THEN WEAKEN UNTIL FT24.
  THE INTENSITY FORECAST IS BASED ON A CONSENSUS OF GUIDANCE DATA
  INCLUDING GSM.
