REMARKS:
290900Z POSITION NEAR 33.1N 148.3E.
29OCT21. TROPICAL STORM (TS) 25W (MALOU), LOCATED APPROXIMATELY 402
NM EAST-SOUTHEAST OF YOKOSUKA, JAPAN, HAS TRACKED NORTHEASTWARD AT
27 KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY (MSI) SHOWS THE SYSTEM HAS SIGNIFICANTLY ELONGATED AS THE
CENTRAL CONVECTION IS SHEARED NORTHEASTWARD OF THE LOW LEVEL
CIRCULATION (LLC). THE MSI LOOP ALSO CLEARLY SHOWS THE LLC HAS
ACCELERATED AND BECOME EMBEDDED IN A NE-SW ORIENTED COLD FRONT AS
COLD AIR STRATOCUMULUS LINES FEED INTO THE LLC. THE INITIAL POSITION
IS PLACED WITH HIGH CONFIDENCE BASED ON THE RAGGED EYE FEATURE IN THE
MSI LOOP. THE INITIAL INTENSITY IS ALSO PLACED WITH HIGH CONFIDENCE
BASED ON THE WEAKENING AGENCY AND AUTOMATED DVORAK ESTIMATES.
ANALYSIS INDICATES TS MALOU IS NOW IN THE COLD BAROCLINIC ZONE UNDER
HIGH (30KT+) VERTICAL WIND SHEAR AND UNDERGOING RAPID EXTRA-TROPICAL
TRANSITION AND IS EXPECTED TO TRANSFORM INTO A GALE-FORCE COLD CORE
LOW WITH AN EXPANSIVE WIND FIELD BY TAU 12. THIS IS THE FINAL
WARNING ON THIS SYSTEM BY THE JOINT TYPHOON WRNCEN PEARL HARBOR HI.
THE SYSTEM WILL BE CLOSELY MONITORED FOR SIGNS OF REGENERATION.
MAXIMUM SIGNIFICANT WAVE HEIGHT AT 290600Z IS 32 FEET.

REASONING NO.24 FOR TY 2120 MALOU (2120)
1.GENERAL COMMENTS
TY MALOU IS LOCATED AT 32.3N, 147.3E. INFORMATION ON THE CURRENT
POSITION IS BASED ON ANIMATED MSI AND SURFACE OBSERVATIONS.
POSITIONAL ACCURACY IS FAIR. CENTRAL PRESSURE IS 965HPA AND
MAXIMUM SUSTAINED WINDS NEAR THE CENTER ARE 75KNOTS. THE SYSTEM IS
IN A NEUTRAL ENVIRONMENT FOR DEVELOPMENT UNDER THE INFLUENCE OF
LOW SSTS, STRONG 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 WINDS DATA ESTIMATED FROM SATELLITE
SCATTEROMETERS.
2.SYNOPTIC SITUATION
THE SYSTEM IS MOVING NORTH-NORTHEASTWARD ALONG THE NORTHWESTERN
PERIPHERY OF A MID-LEVEL SUB-TROPICAL HIGH. ANIMATED MSI SHOWS THE
SYSTEM HAS A BAND WITH A CURVATURE SUGGESTING THE CSC. ANIMATED
MSI SHOWS GOOD CLOUD CHARACTERISTICS OF ANTICYCLONIC OUTFLOW.
WATER VAPOR IMAGERY SHOWS DRY AIR AROUND THE SYSTEM. GCOM-W/AMSR2
89 GHZ MICROWAVE IMAGERY SHOWS THE SYSTEM HAS A BAND WITH
CURVATURE INDICATING THE CSC.
3.TRACK FORECAST
THE SYSTEM WILL GRADUALLY ACCELERATE AND MOVE NORTHEASTWARD UNDER
THE INFLUENCE OF A MID-LATITUDE TROUGH 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.
4.INTENSITY FORECAST
THE SYSTEM WILL WEAKEN UNTIL FT24 IN A STATE OF EXTRATROPICAL
TRANSITION. THE SYSTEM WILL TRANSFORM INTO AN EXTRATROPICAL
CYCLONE BY FT24. THE INTENSITY FORECAST IS BASED ON A CONSENSUS OF
GUIDANCE DATA INCLUDING GSM.

RSMC TROPICAL CYCLONE PROGNOSTIC REASONING
REASONING NO.21 FOR TY 2120 MALOU (2120)
1.GENERAL COMMENTS
TY MALOU IS LOCATED AT 26.2N, 142.5E. INFORMATION ON THE CURRENT
POSITION IS BASED ON THE EYE IN ANIMATED MSI AND SURFACE
OBSERVATIONS. POSITIONAL ACCURACY IS GOOD. CENTRAL PRESSURE IS
965HPA AND MAXIMUM SUSTAINED WINDS ARE 75KNOTS. THE SYSTEM IS IN A
FAVORABLE ENVIRONMENT FOR DEVELOPMENT UNDER THE INFLUENCE OF HIGH
SSTS, WEAK VWS AND GOOD UPPER-LEVEL OUTFLOW. THIS HAS CAUSED THE
SYSTEM TO DEVELOP OVER THE LAST SIX HOURS. INFORMATION ON THE
CURRENT INTENSITY IS BASED ON DVORAK INTENSITY ANALYSES AND
SURFACE OBSERVATIONS.
2.SYNOPTIC SITUATION
THE SYSTEM IS MOVING NORTH-NORTHEASTWARD ALONG THE NORTHWESTERN
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-F17/SSMIS 89 GHZ MICROWAVE IMAGERY SHOWS THE
SYSTEM HAS AN EYE.
3.TRACK FORECAST
THE SYSTEM WILL MOVE NORTH-NORTHEASTWARD ALONG THE PERIPHERY OF A
MID-LEVEL SUB-TROPICAL HIGH UNTIL FT12. THE SYSTEM WILL THEN
GRADUALLY ACCELERATE AND 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.
4.INTENSITY FORECAST
THE SYSTEM WILL MAINTAIN ITS INTENSITY UNTIL FT12 DUE TO THE
INFLUENCE OF INTERACTION WITH GOOD UPPER LEVEL OUTFLOW AND DRY
AIR. THE SYSTEM WILL THEN WEAKEN UNTIL FT24 DUE TO THE INFLUENCE
OF INTERACTION WITH LOW TCHP, STRONG VWS AND DRY AIR. THE SYSTEM
WILL THEN WEAKEN UNTIL FT48 IN A STATE OF EXTRATROPICAL
TRANSITION. THE INTENSITY FORECAST IS BASED ON A CONSENSUS OF
GUIDANCE DATA INCLUDING GSM.

TY MALOU IS LOCATED AT 22.7N, 140.0E. INFORMATION ON THE CURRENT
POSITION IS BASED ON ANIMATED MSI AND SURFACE OBSERVATIONS.
POSITIONAL ACCURACY IS FAIR. CENTRAL PRESSURE IS 975HPA AND
MAXIMUM SUSTAINED WINDS NEAR THE CENTER ARE 65KNOTS. THE SYSTEM IS
IN A FAVORABLE 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 DEVELOP OVER THE LAST SIX
HOURS. INFORMATION ON THE CURRENT INTENSITY IS BASED ON DVORAK
INTENSITY ANALYSES AND SURFACE OBSERVATIONS.
2.SYNOPTIC SITUATION
THE SYSTEM IS MOVING NORTHWARD ALONG THE WESTERN PERIPHERY OF A
MID-LEVEL SUB-TROPICAL HIGH. ANIMATED MSI SHOWS A BAND SPIRALING
AROUND THE EYE BY AT LEAST 360 DEGREES. ANIMATED MSI SHOWS GOOD
CLOUD CHARACTERISTICS OF ANTICYCLONIC OUTFLOW. WATER VAPOR IMAGERY
SHOWS DRY AIR AROUND THE SYSTEM. METOP-A/MHS 85 GHZ MICROWAVE
IMAGERY SHOWS THE SYSTEM HAS A BAND WITH CURVATURE INDICATING THE
CSC.
3.TRACK FORECAST
THE SYSTEM WILL MOVE NORTH-NORTHEASTWARD ALONG THE PERIPHERY OF A
MID-LEVEL SUB-TROPICAL HIGH UNTIL FT24. THE SYSTEM WILL THEN
GRADUALLY ACCELERATE AND 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 UNTIL FT24 BUT LOW THEREAFTER DUE TO
SIGNIFICANT DIFFERENCES AMONG NWP MODEL OUTPUTS.
4.INTENSITY FORECAST
THE SYSTEM WILL DEVELOP UNTIL FT24 DUE TO THE INFLUENCE OF
INTERACTION WITH HIGH SSTS AND GOOD UPPER LEVEL OUTFLOW. THE
SYSTEM WILL THEN WEAKEN UNTIL FT48 IN A STATE OF EXTRATROPICAL
TRANSITION. THE SYSTEM WILL TRANSFORM INTO AN EXTRATROPICAL
CYCLONE BY FT48. THE INTENSITY FORECAST IS BASED ON A CONSENSUS OF
GUIDANCE DATA INCLUDING GSM.
