RSMC TROPICAL CYCLONE PROGNOSTIC REASONING
REASONING NO.46 FOR EXTRATROPICAL CYCLONE LOCATED AT 43N 166E
1.GENERAL COMMENTS
  KROSA (2509) HAS TRANSFORMED INTO AN EXTRATROPICAL CYCLONE. THE
  EXTRATROPICAL CYCLONE IS LOCATED AT 43N, 166E. INFORMATION ON THE
  CURRENT POSITION IS BASED ON ANIMATED MSI AND SURFACE
  OBSERVATIONS. CENTRAL PRESSURE IS 990HPA AND MAXIMUM SUSTAINED
  WINDS ARE 40KNOTS. THE SYSTEM IS IN AN UNFAVORABLE ENVIRONMENT FOR
  DEVELOPMENT UNDER THE INFLUENCE OF LOW SSTS, LOW TCHP AND STRONG
  VWS. 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 SURFACE OBSERVATIONS.
2.SYNOPTIC SITUATION
  THE SYSTEM IS MOVING EAST-NORTHEASTWARD ALONG THE NORTHWESTERN
  PERIPHERY OF A MID-LEVEL SUB-TROPICAL HIGH. ANIMATED MSI SHOWS THE
  SEPARATION OF ACTIVE CONVECTIVE CLOUD CLUSTERS FROM THE CSC.
  ANIMATED MSI SHOWS GOOD CLOUD CHARACTERISTICS OF ANTICYCLONIC
  OUTFLOW. WATER VAPOR IMAGERY SHOWS DRY AIR AROUND THE SYSTEM.
  NOAA-21/ATMS 85 GHZ MICROWAVE IMAGERY SHOWS THE SYSTEM HAS ACTIVE
  CONVECTIVE CLOUD CLUSTERS AROUND THE CSC.
3.TRACK FORECAST
  SEE THE MARINE WARNING (WWJP27 RJTD).
4.INTENSITY FORECAST
  SEE THE MARINE WARNING (WWJP27 RJTD).
5.REMARKS
  THIS WILL BE THE FINAL PROGNOSTIC REASONING FOR THE SYSTEM.
