DISCUSSION FROM RSMC
-----------------------------------
TY HINNAMNOR IS LOCATED AT 27.7N, 124.5E. INFORMATION ON 
THE CURRENT POSITION IS BASED ON THE EYE IN ANIMATED MSI 
AND SURFACE OBSERVATIONS. POSITIONAL ACCURACY IS GOOD. 
CENTRAL PRESSURE IS 945HPA AND MAXIMUM SUSTAINED WINDS 
NEAR THE CENTER ARE 85KNOTS. THE SYSTEM IS IN A NEUTRAL 
ENVIRONMENT FOR DEVELOPMENT UNDER THE INFLUENCE OF HIGH 
SSTS, HIGH TCHP, WEAK VWS, GOOD UPPER-LEVEL OUTFLOW AND 
DRY AIR. THIS HAS CAUSED THE SYSTEM 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 NORTHWARD ALONG THE WESTERN PERIPHERY 
OF A MID-LEVEL SUB-TROPICAL HIGH. ANIMATED MSI SHOWS THE 
SYSTEM HAS AN EYE. ANIMATED MSI SHOWS GOOD CLOUD 
CHARACTERISTICS OF ANTICYCLONIC OUTFLOW. WATER VAPOR 
IMAGERY SHOWS DRY AIR AROUND THE SYSTEM. DMSP-F18/SSMIS 89 
GHZ MICROWAVE IMAGERY SHOWS THE SYSTEM HAS AN EYE.

THE SYSTEM WILL MOVE NORTHWARD ALONG THE PERIPHERY OF A 
MID-LEVEL SUB-TROPICAL HIGH UNTIL FT12. THE SYSTEM WILL 
THEN GRADUALLY TURN TO THE NORTH-NORTHEAST ALONG THE 
PERIPHERY OF A MID-LEVEL SUB-TROPICAL HIGH UNTIL FT24. THE 
SYSTEM WILL THEN GRADUALLY ACCELERATE AND MOVE NORTH-
NORTHEASTWARD UNDER THE INFLUENCE OF MID-LATITUDE 
PREVAILING WESTERLIES UNTIL FT48. THE SYSTEM WILL THEN 
GRADUALLY TURN TO THE NORTH UNDER THE INFLUENCE OF A MID-
LATITUDE TROUGH UNTIL FT72. THE TRACK FORECAST IS BASED ON 
GSM PREDICTIONS, AND REFERENCE TO OTHER NWP MODELS. TRACK 
FORECAST CONFIDENCE IS HIGH UNTIL FT24 BUT LOW THEREAFTER 
DUE TO SIGNIFICANT DIFFERENCES AMONG NWP MODEL OUTPUTS.

THE SYSTEM WILL DEVELOP UNTIL FT12 DUE TO THE INFLUENCE OF 
INTERACTION WITH HIGH SSTS, HIGH TCHP, WEAK VWS AND GOOD 
UPPER LEVEL OUTFLOW. THE SYSTEM WILL THEN MAINTAIN ITS 
INTENSITY UNTIL FT24 DUE TO THE INFLUENCE OF INTERACTION 
WITH HIGH SSTS, REDUCED TCHP, INCREASED VWS AND GOOD UPPER 
LEVEL OUTFLOW. THE SYSTEM WILL THEN WEAKEN UNTIL FT48 DUE 
TO THE INFLUENCE OF INTERACTION WITH LOWER SSTS, LOW TCHP 
AND STRONG VWS. THE SYSTEM WILL THEN WEAKEN UNTIL FT72 DUE 
TO THE INFLUENCE OF INTERACTION WITH LAND, LOW SSTS, LOW 
TCHP AND STRONG VWS. THE SYSTEM WILL TRANSFORM INTO AN 
EXTRATROPICAL CYCLONE BY FT72. THE INTENSITY FORECAST IS 
BASED ON A CONSENSUS OF GUIDANCE DATA INCLUDING GSM.
