1.GENERAL COMMENTS
TS YUTU IS LOCATED AT 17.4N, 118.1E. INFORMATION ON THE CURRENT
POSITION IS BASED ON ANIMATED MSI AND SURFACE OBSERVATIONS.
POSITIONAL ACCURACY IS FAIR. THE SYSTEM IS IN AN UNFAVORABLE
ENVIRONMENT FOR DEVELOPMENT UNDER THE INFLUENCE OF LAND AND DRY
AIR. THIS HAS CAUSED THE SYSTEM TO WEAKEN OVER THE LAST SIX HOURS.
HOWEVER, THE INFLUENCE OF HIGH SSTS AND GOOD UPPER-LEVEL OUTFLOW
ARE FAVORABLE FOR SYSTEM DEVELOPMENT. INFORMATION ON CURRENT
INTENSITY IS BASED ON DVORAK INTENSITY ANALYSES AND SURFACE
OBSERVATIONS.
2.SYNOPTIC SITUATION
THE SYSTEM IS MOVING SLOWLY NORTHWESTWARD DUE TO WEAK STEERING
FLOW. ANIMATED MSI SHOWS CB CLUSTERS GATHERING AROUND THE CSC AND
FORMING A CURVED BAND. ANIMATED MSI SHOWS GOOD CLOUD
CHARACTERISTICS OF ANTICYCLONIC OUTFLOW. WATER VAPOR IMAGERY SHOWS
DRY AIR IN THE DIRECTION OF THE MOVEMENT. DMSP-F17/SSMIS 89 GHZ
MICROWAVE IMAGERY SHOWS THE SYSTEM HAS ACTIVE CONVECTIVE CLOUD
CLUSTERS AROUND THE CSC.
3.TRACK FORECAST
THE SYSTEM WILL MOVE NORTH-NORTHWESTWARD DUE TO WEAK STEERING FLOW
UNTIL FT24. THE SYSTEM WILL THEN GRADUALLY DECELERATE AND MOVE
NORTHWARD UNTIL FT48. THE SYSTEM WILL THEN REMAIN ALMOST
STATIONARY UNTIL FT72. THE JMA TRACK FORECAST IS BASED ON GSM
PREDICTIONS, AND REFERENCE TO OTHER NWP MODELS. JMA TRACK FORECAST
CONFIDENCE IS FAIR UNTIL FT24 BUT LOW THEREAFTER DUE TO

REASONING NO.29 FOR TY 1826 YUTU (1826)
1.GENERAL COMMENTS
TY YUTU IS LOCATED AT 17.9N, 129.0E. INFORMATION ON THE CURRENT
POSITION IS BASED ON THE EYE IN MICROWAVE IMAGERY AND SURFACE
OBSERVATIONS. POSITIONAL ACCURACY IS GOOD. THE SYSTEM IS IN A
NEUTRAL ENVIRONMENT FOR DEVELOPMENT UNDER THE INFLUENCE OF HIGH
SSTS, WEAK VWS, REDUCED TCHP, GOOD UPPER-LEVEL OUTFLOW AND DRY
AIR. THIS HAS CAUSED THE SYSTEM TO MAINTAIN ITS INTENSITY OVER THE
LAST SIX HOURS. INFORMATION ON CURRENT INTENSITY IS BASED ON
DVORAK INTENSITY ANALYSES AND SURFACE OBSERVATIONS.
2.SYNOPTIC SITUATION
THE SYSTEM IS MOVING WESTWARD BETWEEN TWO MID-LEVEL SUB-TROPICAL
HIGHS. 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.
3.TRACK FORECAST
THE SYSTEM WILL MOVE WESTWARD DUE TO WEAK STEERING FLOW UNTIL
FT72. THE SYSTEM WILL HIT THE PHILIPPINES BY FT48. THE SYSTEM WILL
THEN GRADUALLY DECELERATE AND MOVE NORTHWESTWARD ALONG THE
PERIPHERY OF A MID-LEVEL SUB-TROPICAL HIGH UNTIL FT96. THE SYSTEM
WILL THEN GRADUALLY CHANGE ITS COURSE TO THE NORTH UNTIL FT120.
THE JMA TRACK FORECAST IS BASED ON GSM PREDICTIONS. JMA TRACK
FORECAST CONFIDENCE IS FAIR UNTIL FT48 BUT LOW THEREAFTER DUE TO
SIGNIFICANT DIFFERENCES AMONG NUMERICAL MODEL OUTPUTS.
4.INTENSITY FORECAST
THE SYSTEM WILL WEAKEN UNTIL FT24 DUE TO THE INFLUENCE OF DRY AIR.
THE SYSTEM WILL THEN WEAKEN RAPIDLY UNTIL FT48 DUE TO ITS
