1.GENERAL COMMENTS
ETAU (2622) HAS WEAKENED TO TD INTENSITY. THE TD IS LOCATED AT
32N, 167E. INFORMATION ON THE CURRENT POSITION IS BASED ON
ANIMATED MSI AND SURFACE OBSERVATIONS. CENTRAL PRESSURE IS 998HPA
AND MAXIMUM SUSTAINED WINDS ARE LESS THAN 30KNOTS. THE SYSTEM IS
IN AN UNFAVORABLE ENVIRONMENT FOR DEVELOPMENT UNDER THE INFLUENCE
OF LOW TCHP AND STRONG VWS. THIS HAS CAUSED THE SYSTEM TO WEAKEN
OVER THE LAST SIX HOURS. INFORMATION ON THE CURRENT INTENSITY IS
BASED ON DVORAK INTENSITY ANALYSES AND SURFACE WINDS DATA
ESTIMATED FROM SEA SURFACE AMVS.
2.SYNOPTIC SITUATION
THE SYSTEM IS MOVING EAST-NORTHEASTWARD DUE TO INTERACTION WITH A
NEARBY TROPICAL CYCLONE. ANIMATED MSI SHOWS CB CLUSTERS ARE
SCATTERED AROUND THE CSC. GPM/GMI 89 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.

REASONING NO.17 FOR TS 2622 ETAU (2622)
1.GENERAL COMMENTS
TS ETAU IS LOCATED AT 31.1N, 166.0E. INFORMATION ON THE CURRENT
POSITION IS BASED ON ANIMATED MSI AND SURFACE OBSERVATIONS.
POSITIONAL ACCURACY IS FAIR. CENTRAL PRESSURE IS 996HPA AND
MAXIMUM SUSTAINED WINDS NEAR THE CENTER ARE 35KNOTS. THE SYSTEM IS
IN A NEUTRAL ENVIRONMENT FOR DEVELOPMENT UNDER THE INFLUENCE OF
WEAK VWS AND LOW TCHP. 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.
2.SYNOPTIC SITUATION
THE SYSTEM IS MOVING EASTWARD DUE TO INTERACTION WITH A NEARBY
TROPICAL CYCLONE. ANIMATED MSI SHOWS THE SEPARATION OF ACTIVE
CONVECTIVE CLOUD CLUSTERS FROM THE CSC. WATER VAPOR IMAGERY SHOWS
DRY AIR AROUND THE SYSTEM. GPM/GMI 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 NORTH-NORTHEASTWARD
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 A MID-LATITUDE TROUGH
UNTIL FT48. THE TRACK FORECAST IS BASED ON GSM PREDICTIONS, AND
REFERENCE TO OTHER NWP MODELS. TRACK FORECAST CONFIDENCE IS LOW
DUE TO SIGNIFICANT DIFFERENCES AMONG NWP MODEL OUTPUTS.
4.INTENSITY FORECAST
THE SYSTEM WILL DEVELOP 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.

RSMC TROPICAL CYCLONE PROGNOSTIC REASONING
REASONING NO.16 FOR TS 2622 ETAU (2622)
1.GENERAL COMMENTS
TS ETAU IS LOCATED AT 30.7N, 165.6E. INFORMATION ON THE CURRENT
POSITION IS BASED ON ANIMATED MSI AND SURFACE OBSERVATIONS.
POSITIONAL ACCURACY IS FAIR. CENTRAL PRESSURE IS 996HPA AND
MAXIMUM SUSTAINED WINDS NEAR THE CENTER ARE 35KNOTS. THE SYSTEM IS
IN A NEUTRAL ENVIRONMENT FOR DEVELOPMENT UNDER THE INFLUENCE OF
LOW TCHP AND WEAK VWS. HOWEVER, THE LIMITED FIRMNESS OF ITS
STRUCTURE HAS CAUSED IT TO WEAKEN 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 EASTWARD DUE TO INTERACTION WITH A NEARBY
TROPICAL CYCLONE. 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. METOP-C/MHS 85 GHZ MICROWAVE
IMAGERY SHOWS THE SYSTEM HAS ACTIVE CONVECTIVE CLOUD CLUSTERS
AROUND THE CSC.
3.TRACK FORECAST
THE SYSTEM WILL MOVE NORTHEASTWARD DUE TO INTERACTION WITH A
NEARBY TROPICAL CYCLONE UNTIL FT24. THE SYSTEM WILL THEN MOVE
NORTHWARD UNDER THE INFLUENCE OF A MID-LATITUDE TROUGH UNTIL FT48.
THE SYSTEM WILL THEN MOVE NORTH-NORTHEASTWARD UNTIL FT72. THE
TRACK FORECAST IS BASED ON GSM PREDICTIONS, AND REFERENCE TO OTHER
NWP MODELS. TRACK FORECAST CONFIDENCE IS LOW DUE TO SIGNIFICANT
DIFFERENCES AMONG NWP MODEL OUTPUTS.
4.INTENSITY FORECAST
THE SYSTEM WILL MAINTAIN ITS INTENSITY UNTIL FT48 DUE TO THE
INFLUENCE OF INTERACTION WITH LOWER SSTS, LOW TCHP, INCREASED VWS
AND GOOD UPPER-LEVEL OUTFLOW. THE SYSTEM WILL THEN WEAKEN UNTIL
FT72 DUE TO THE INFLUENCE OF INTERACTION WITH LOW SSTS, LOW TCHP
AND STRONG VWS. THE SYSTEM WILL WEAKEN TO TD INTENSITY BY FT72.
THE INTENSITY FORECAST IS BASED ON A CONSENSUS OF GUIDANCE DATA
INCLUDING GSM.

RSMC TROPICAL CYCLONE PROGNOSTIC REASONING
REASONING NO.14 FOR TS 2622 ETAU (2622)
1.GENERAL COMMENTS
TS ETAU IS LOCATED AT 30.7N, 164.7E. INFORMATION ON THE CURRENT
POSITION IS BASED ON ANIMATED MSI AND SURFACE OBSERVATIONS.
POSITIONAL ACCURACY IS FAIR. CENTRAL PRESSURE IS 994HPA AND
MAXIMUM SUSTAINED WINDS NEAR THE CENTER ARE 40KNOTS. THE SYSTEM IS
IN A NEUTRAL ENVIRONMENT FOR DEVELOPMENT UNDER THE INFLUENCE OF
LOW TCHP AND GOOD UPPER-LEVEL OUTFLOW. 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 SLOWLY WEST-NORTHWESTWARD DUE TO INTERACTION
WITH A NEARBY TROPICAL CYCLONE. ANIMATED MSI SHOWS CB CLUSTERS
GATHERING AROUND THE CSC AND FORMING A CURVED BAND. ANIMATED MSI
SHOWS THE CLOUD CHARACTERISTICS OF ANTICYCLONIC OUTFLOW ARE NOW
DISTINCT. WATER VAPOR IMAGERY SHOWS DRY AIR AROUND THE SYSTEM.
NOAA-20/ATMS 85 GHZ MICROWAVE IMAGERY SHOWS THE SYSTEM HAS A BAND
WITH CURVATURE INDICATING THE CSC.
3.TRACK FORECAST
THE SYSTEM WILL REMAIN ALMOST STATIONARY DUE TO INTERACTION WITH A
NEARBY TROPICAL CYCLONE UNTIL FT48. THE SYSTEM WILL THEN MOVE
NORTHEASTWARD 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 LOW
DUE TO SIGNIFICANT DIFFERENCES AMONG NWP MODEL OUTPUTS.
4.INTENSITY FORECAST
THE SYSTEM WILL MAINTAIN ITS INTENSITY UNTIL FT48. THE SYSTEM WILL
THEN WEAKEN UNTIL FT72 DUE TO THE INFLUENCE OF INTERACTION WITH
LOWER SSTS, LOW TCHP AND INCREASED VWS. THE SYSTEM WILL WEAKEN TO
TD INTENSITY BY FT72. THE INTENSITY FORECAST IS BASED ON A
CONSENSUS OF GUIDANCE DATA INCLUDING GSM.

RSMC TROPICAL CYCLONE PROGNOSTIC REASONING
REASONING NO.13 FOR TS 2622 ETAU (2622)
1.GENERAL COMMENTS
TS ETAU IS LOCATED AT 29.9N, 165.5E. INFORMATION ON THE CURRENT
POSITION IS BASED ON ANIMATED MSI AND SURFACE OBSERVATIONS.
POSITIONAL ACCURACY IS FAIR. CENTRAL PRESSURE IS 994HPA AND
MAXIMUM SUSTAINED WINDS NEAR THE CENTER ARE 40KNOTS. THE SYSTEM IS
IN A NEUTRAL ENVIRONMENT FOR DEVELOPMENT UNDER THE INFLUENCE OF
LOW TCHP, STRONG VWS AND GOOD UPPER-LEVEL OUTFLOW. 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 NORTHWARD ALONG THE WESTERN PERIPHERY OF A
MID-LEVEL SUB-TROPICAL HIGH. ANIMATED MSI SHOWS CB CLUSTERS
GATHERING AROUND THE CSC AND FORMING A CURVED BAND. WATER VAPOR
IMAGERY SHOWS DRY AIR AROUND THE SYSTEM. DMSP-F17/SSMIS 89 GHZ
MICROWAVE IMAGERY SHOWS THE SYSTEM HAS ACTIVE CONVECTIVE CLOUD
CLUSTERS AROUND THE CSC.
3.TRACK FORECAST
THE SYSTEM WILL GRADUALLY DECELERATE AND MOVE NORTHWESTWARD ALONG
THE PERIPHERY OF A MID-LEVEL SUB-TROPICAL HIGH UNTIL FT06. THE
SYSTEM WILL THEN REMAIN ALMOST STATIONARY UNTIL FT36. THE SYSTEM
WILL THEN MOVE SLOWLY NORTHEASTWARD UNDER THE INFLUENCE OF
MID-LATITUDE PREVAILING WESTERLIES UNTIL FT72. THE TRACK FORECAST
IS BASED ON GSM PREDICTIONS, AND REFERENCE TO OTHER NWP MODELS.
TRACK FORECAST CONFIDENCE IS LOW DUE TO SIGNIFICANT DIFFERENCES
AMONG NWP MODEL OUTPUTS.
4.INTENSITY FORECAST
THE SYSTEM WILL GRADUALLY WEAKEN UNTIL FT72 DUE TO THE INFLUENCE
OF INTERACTION WITH LOWER SSTS AND LOW TCHP. THE SYSTEM WILL
WEAKEN TO TD INTENSITY BY FT72. THE INTENSITY FORECAST IS BASED ON
A CONSENSUS OF GUIDANCE DATA INCLUDING GSM.

1.GENERAL COMMENTS
TS ETAU IS LOCATED AT 28.2N, 165.8E. INFORMATION ON THE CURRENT
POSITION IS BASED ON ANIMATED MSI AND SURFACE OBSERVATIONS.
POSITIONAL ACCURACY IS GOOD. CENTRAL PRESSURE IS 994HPA AND
MAXIMUM SUSTAINED WINDS NEAR THE CENTER ARE 40KNOTS. THE SYSTEM IS
IN A NEUTRAL ENVIRONMENT FOR DEVELOPMENT UNDER THE INFLUENCE OF
HIGH SSTS, GOOD UPPER-LEVEL OUTFLOW, REDUCED TCHP, STRONG VWS 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 NORTHWARD ALONG THE WESTERN PERIPHERY OF A
MID-LEVEL SUB-TROPICAL HIGH. ANIMATED MSI SHOWS CB CLUSTERS
GATHERING AROUND THE CSC AND STARTING TO FORM A CURVED BAND. WATER
VAPOR IMAGERY SHOWS DRY AIR AROUND THE SYSTEM. DMSP-F18/SSMIS 89
GHZ MICROWAVE IMAGERY SHOWS THE SYSTEM HAS ACTIVE CONVECTIVE CLOUD
CLUSTERS AROUND THE CSC.
3.TRACK FORECAST
THE SYSTEM WILL MOVE NORTHWESTWARD DUE TO INTERACTION WITH A
NEARBY TROPICAL CYCLONE UNTIL FT12. THE SYSTEM WILL THEN REMAIN
ALMOST STATIONARY UNTIL FT24. THE SYSTEM WILL THEN MOVE
NORTHEASTWARD UNTIL FT48. THE SYSTEM WILL THEN MOVE
NORTH-NORTHEASTWARD ALONG THE PERIPHERY OF A MID-LEVEL
SUB-TROPICAL HIGH UNTIL FT72. THE TRACK FORECAST IS BASED ON GSM
PREDICTIONS, AND REFERENCE TO OTHER NWP MODELS. TRACK FORECAST
CONFIDENCE IS LOW DUE TO SIGNIFICANT DIFFERENCES AMONG NWP MODEL
OUTPUTS.
4.INTENSITY FORECAST
THE SYSTEM WILL MAINTAIN ITS INTENSITY UNTIL FT12 DUE TO THE
INFLUENCE OF INTERACTION WITH HIGH SSTS, GOOD UPPER-LEVEL OUTFLOW
AND LOW TCHP. THE SYSTEM WILL THEN WEAKEN UNTIL FT72 DUE TO THE
INFLUENCE OF INTERACTION WITH LOWER SSTS AND LOW TCHP. THE SYSTEM
WILL WEAKEN TO TD INTENSITY BY FT72. THE INTENSITY FORECAST IS

RSMC TROPICAL CYCLONE PROGNOSTIC REASONING
REASONING NO.10 FOR TS 2622 ETAU (2622)
1.GENERAL COMMENTS
TS ETAU IS LOCATED AT 26.1N, 166.1E. INFORMATION ON THE CURRENT
POSITION IS BASED ON ANIMATED MSI AND SURFACE OBSERVATIONS.
POSITIONAL ACCURACY IS FAIR. CENTRAL PRESSURE IS 996HPA AND
MAXIMUM SUSTAINED WINDS NEAR THE CENTER ARE 40KNOTS. THE SYSTEM IS
IN A NEUTRAL ENVIRONMENT FOR DEVELOPMENT UNDER THE INFLUENCE OF
HIGH SSTS, GOOD UPPER-LEVEL OUTFLOW, STRONG VWS 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.
2.SYNOPTIC SITUATION
THE SYSTEM IS MOVING NORTH-NORTHWESTWARD DUE TO INTERACTION WITH A
NEARBY TROPICAL CYCLONE. ANIMATED MSI SHOWS THE SEPARATION OF
ACTIVE CONVECTIVE CLOUD CLUSTERS FROM THE CSC. WATER VAPOR IMAGERY
SHOWS DRY AIR IN THE DIRECTION OF THE MOVEMENT. NOAA-20/ATMS 85
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 INTERACTION WITH A
NEARBY TROPICAL CYCLONE UNTIL FT24. THE SYSTEM WILL THEN MOVE
SLOWLY NORTHWARD DUE TO INTERACTION WITH A NEARBY TROPICAL CYCLONE
UNTIL FT48. THE SYSTEM WILL THEN MOVE NORTHEASTWARD UNDER THE
INFLUENCE OF MID-LATITUDE PREVAILING WESTERLIES UNTIL FT72. THE
TRACK FORECAST IS BASED ON GSM PREDICTIONS, AND REFERENCE TO OTHER
NWP MODELS. TRACK FORECAST CONFIDENCE IS LOW DUE TO SIGNIFICANT
DIFFERENCES AMONG NWP MODEL OUTPUTS.
4.INTENSITY FORECAST
THE SYSTEM WILL DEVELOP UNTIL FT12 DUE TO THE INFLUENCE OF
INTERACTION WITH HIGH SSTS AND GOOD UPPER-LEVEL OUTFLOW. THE
SYSTEM WILL THEN WEAKEN UNTIL FT72 DUE TO THE INFLUENCE OF
INTERACTION WITH LOWER SSTS AND REDUCED TCHP. THE SYSTEM WILL
WEAKEN TO TD INTENSITY BY FT72. THE INTENSITY FORECAST IS BASED ON
A CONSENSUS OF GUIDANCE DATA INCLUDING GSM.

REASONING NO. 9 FOR TS 2622 ETAU (2622)
1.GENERAL COMMENTS
TS ETAU IS LOCATED AT 25.1N, 166.5E. INFORMATION ON THE CURRENT
POSITION IS BASED ON ANIMATED MSI AND SURFACE OBSERVATIONS.
POSITIONAL ACCURACY IS FAIR. CENTRAL PRESSURE IS 996HPA AND
MAXIMUM SUSTAINED WINDS NEAR THE CENTER ARE 40KNOTS. THE SYSTEM IS
IN A NEUTRAL ENVIRONMENT FOR DEVELOPMENT UNDER THE INFLUENCE OF
HIGH SSTS, GOOD UPPER-LEVEL OUTFLOW, STRONG VWS 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 NORTHWESTWARD DUE TO INTERACTION WITH A
NEARBY TROPICAL CYCLONE. ANIMATED MSI SHOWS THE SEPARATION OF
ACTIVE CONVECTIVE CLOUD CLUSTERS FROM THE CSC. WATER VAPOR IMAGERY
SHOWS DRY AIR IN THE DIRECTION OF THE MOVEMENT. METOP-B/MHS 85 GHZ
MICROWAVE IMAGERY SHOWS THE SYSTEM HAS A BAND WITH CURVATURE
INDICATING THE CSC.
3.TRACK FORECAST
THE SYSTEM WILL MOVE NORTHWARD DUE TO INTERACTION WITH A NEARBY
TROPICAL CYCLONE UNTIL FT48. THE SYSTEM WILL THEN MOVE
NORTH-NORTHEASTWARD DUE TO INTERACTION WITH A NEARBY TROPICAL
CYCLONE UNTIL FT72. THE SYSTEM WILL THEN MOVE NORTHEASTWARD UNDER
THE INFLUENCE OF MID-LATITUDE PREVAILING WESTERLIES UNTIL FT96.
THE TRACK FORECAST IS BASED ON GSM PREDICTIONS, AND REFERENCE TO
OTHER NWP MODELS. TRACK FORECAST CONFIDENCE IS LOW DUE TO
SIGNIFICANT DIFFERENCES AMONG NWP MODEL OUTPUTS.
4.INTENSITY FORECAST
THE SYSTEM WILL MAINTAIN ITS INTENSITY UNTIL FT24 DUE TO THE
INFLUENCE OF INTERACTION WITH HIGH SSTS, GOOD UPPER-LEVEL OUTFLOW,
STRONG VWS AND DRY AIR. THE SYSTEM WILL THEN GRADUALLY WEAKEN
UNTIL FT96 DUE TO THE INFLUENCE OF INTERACTION WITH REDUCED TCHP,
LOWER SSTS, GOOD UPPER-LEVEL OUTFLOW AND WEAK VWS. THE SYSTEM WILL
WEAKEN TO TD INTENSITY BY FT96. THE INTENSITY FORECAST IS BASED ON
A CONSENSUS OF GUIDANCE DATA INCLUDING GSM.

RSMC TROPICAL CYCLONE PROGNOSTIC REASONING
REASONING NO. 7 FOR TS 2622 ETAU (2622)
1.GENERAL COMMENTS
TS ETAU IS LOCATED AT 24.0N, 167.0E. INFORMATION ON THE CURRENT
POSITION IS BASED ON ANIMATED MSI AND SURFACE OBSERVATIONS.
POSITIONAL ACCURACY IS FAIR. CENTRAL PRESSURE IS 996HPA AND
MAXIMUM SUSTAINED WINDS NEAR THE CENTER ARE 40KNOTS. THE SYSTEM IS
IN A NEUTRAL ENVIRONMENT FOR DEVELOPMENT UNDER THE INFLUENCE OF
HIGH SSTS, 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.
2.SYNOPTIC SITUATION
THE SYSTEM IS MOVING NORTHWARD ALONG THE WESTERN PERIPHERY OF A
MID-LEVEL SUB-TROPICAL HIGH. ANIMATED MSI SHOWS CB CLUSTERS
GATHERING AROUND THE CSC AND FORMING A CURVED BAND. ANIMATED MSI
SHOWS GOOD CLOUD CHARACTERISTICS OF ANTICYCLONIC OUTFLOW. GPM/GMI
89 GHZ MICROWAVE IMAGERY SHOWS THE SYSTEM HAS A BAND WITH
CURVATURE INDICATING THE CSC.
3.TRACK FORECAST
THE SYSTEM WILL MOVE NORTH-NORTHWESTWARD ALONG THE PERIPHERY OF A
MID-LEVEL SUB-TROPICAL HIGH UNTIL FT24. THE SYSTEM WILL THEN MOVE
NORTH-NORTHWESTWARD DUE TO INTERACTION WITH A NEARBY TROPICAL
CYCLONE UNTIL FT48. THE SYSTEM WILL THEN MOVE SLOWLY NORTHEASTWARD
UNTIL FT72. THE SYSTEM WILL THEN GRADUALLY ACCELERATE AND MOVE
NORTHEASTWARD UNDER THE INFLUENCE OF A MID-LATITUDE TROUGH UNTIL
FT120. THE TRACK FORECAST IS BASED ON GSM PREDICTIONS, AND
REFERENCE TO OTHER NWP MODELS. TRACK FORECAST CONFIDENCE IS LOW
DUE TO SIGNIFICANT DIFFERENCES AMONG NWP MODEL OUTPUTS.
4.INTENSITY FORECAST
THE SYSTEM WILL GRADUALLY DEVELOP UNTIL FT24 DUE TO THE INFLUENCE
OF INTERACTION WITH HIGH SSTS, GOOD UPPER-LEVEL OUTFLOW AND STRONG
VWS. THE SYSTEM WILL THEN GRADUALLY WEAKEN UNTIL FT120 DUE TO THE
INFLUENCE OF INTERACTION WITH LOWER SSTS, LOW TCHP AND GOOD
UPPER-LEVEL OUTFLOW. THE SYSTEM WILL WEAKEN TO TD INTENSITY BY
FT120. THE INTENSITY FORECAST IS BASED ON A CONSENSUS OF GUIDANCE
DATA INCLUDING GSM.

WTPQ31 RJTD 271800
RSMC TROPICAL CYCLONE PROGNOSTIC REASONING
REASONING NO. 6 FOR TS 2622 ETAU (2622)
1.GENERAL COMMENTS
TS ETAU IS LOCATED AT 22.8N, 168.1E. INFORMATION ON THE CURRENT
POSITION IS BASED ON ANIMATED MSI AND SURFACE OBSERVATIONS.
POSITIONAL ACCURACY IS FAIR. CENTRAL PRESSURE IS 996HPA AND
MAXIMUM SUSTAINED WINDS NEAR THE CENTER ARE 40KNOTS. THE SYSTEM IS
IN A FAVORABLE ENVIRONMENT FOR DEVELOPMENT UNDER THE INFLUENCE OF
HIGH SSTS 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 NORTHWARD ALONG THE WESTERN PERIPHERY OF A
MID-LEVEL SUB-TROPICAL HIGH. ANIMATED MSI SHOWS THE FORMATION OF A
BAND WITH A CURVATURE SUGGESTING THE CSC. ANIMATED MSI SHOWS GOOD
CLOUD CHARACTERISTICS OF ANTICYCLONIC OUTFLOW. NOAA-21/ATMS 85 GHZ
MICROWAVE IMAGERY SHOWS THE SYSTEM HAS A BAND WITH CURVATURE
INDICATING THE CSC.
3.TRACK FORECAST
THE SYSTEM WILL MOVE NORTH-NORTHWESTWARD ALONG THE PERIPHERY OF A
MID-LEVEL SUB-TROPICAL HIGH UNTIL FT48. THE SYSTEM WILL THEN
GRADUALLY TURN TO THE NORTH-NORTHEAST DUE TO INTERACTION WITH A
NEARBY TROPICAL CYCLONE UNTIL FT120. THE TRACK FORECAST IS BASED
ON GSM PREDICTIONS, AND REFERENCE TO OTHER NWP MODELS. TRACK
FORECAST CONFIDENCE IS LOW DUE TO SIGNIFICANT DIFFERENCES AMONG
NWP MODEL OUTPUTS.
4.INTENSITY FORECAST
THE SYSTEM WILL MAINTAIN ITS INTENSITY UNTIL FT24 DUE TO THE

RSMC TROPICAL CYCLONE PROGNOSTIC REASONING
REASONING NO. 5 FOR TS 2622 ETAU (2622)
1.GENERAL COMMENTS
TS ETAU IS LOCATED AT 22.2N, 168.1E. INFORMATION ON THE CURRENT
POSITION IS BASED ON ANIMATED MSI AND SURFACE OBSERVATIONS.
POSITIONAL ACCURACY IS FAIR. CENTRAL PRESSURE IS 998HPA AND
MAXIMUM SUSTAINED WINDS NEAR THE CENTER ARE 35KNOTS. THE SYSTEM IS
IN A FAVORABLE ENVIRONMENT FOR DEVELOPMENT UNDER THE INFLUENCE OF
HIGH SSTS, WEAK VWS AND GOOD UPPER-LEVEL OUTFLOW. HOWEVER, THE
LIMITED FIRMNESS OF ITS STRUCTURE 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.
2.SYNOPTIC SITUATION
THE SYSTEM IS MOVING NORTH-NORTHWESTWARD ALONG THE SOUTHWESTERN
PERIPHERY OF A MID-LEVEL SUB-TROPICAL HIGH. ANIMATED MSI SHOWS CB
CLUSTERS GATHERING AROUND THE CSC. ANIMATED MSI SHOWS GOOD CLOUD
CHARACTERISTICS OF ANTICYCLONIC OUTFLOW. GPM/GMI 89 GHZ MICROWAVE
IMAGERY SHOWS THE SYSTEM HAS ACTIVE CONVECTIVE CLOUD CLUSTERS
AROUND THE CSC.
3.TRACK FORECAST
THE SYSTEM WILL GRADUALLY TURN TO THE NORTH-NORTHEAST ALONG THE
PERIPHERY OF A MID-LEVEL SUB-TROPICAL HIGH UNTIL FT96. THE SYSTEM
WILL THEN MOVE EASTWARD DUE TO INTERACTION WITH A NEARBY TROPICAL
CYCLONE UNTIL FT120. THE TRACK FORECAST IS BASED ON GSM
PREDICTIONS, AND REFERENCE TO OTHER NWP MODELS. TRACK FORECAST
CONFIDENCE IS FAIR UNTIL FT48 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 GRADUALLY WEAKEN UNTIL FT120 DUE TO THE INFLUENCE
OF INTERACTION WITH LOWER SSTS, REDUCED TCHP AND INCREASED VWS.
THE SYSTEM WILL WEAKEN TO TD INTENSITY BY FT120. THE INTENSITY
FORECAST IS BASED ON A CONSENSUS OF GUIDANCE DATA INCLUDING GSM.

RSMC TROPICAL CYCLONE PROGNOSTIC REASONING
REASONING NO. 4 FOR TS 2622 ETAU (2622)
1.GENERAL COMMENTS
A TD PREVIOUSLY LOCATED AT 20.7N, 168.1E HAS BEEN UPGRADED TO TS
(ETAU) STATUS. TS ETAU IS LOCATED AT 21.4N, 168.3E. INFORMATION ON
THE CURRENT POSITION IS BASED ON ANIMATED MSI AND SURFACE
OBSERVATIONS. POSITIONAL ACCURACY IS FAIR. CENTRAL PRESSURE IS
998HPA AND MAXIMUM SUSTAINED WINDS NEAR THE CENTER ARE 35KNOTS.
THE SYSTEM IS IN A FAVORABLE ENVIRONMENT FOR DEVELOPMENT UNDER THE
INFLUENCE OF HIGH SSTS, HIGH TCHP, 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 NORTHWARD ALONG THE WESTERN PERIPHERY OF A
MID-LEVEL SUB-TROPICAL HIGH. ANIMATED MSI SHOWS CB CLUSTERS HAVE
GATHERED AROUND THE CSC. ANIMATED MSI SHOWS GOOD CLOUD
CHARACTERISTICS OF ANTICYCLONIC OUTFLOW. GCOM-W/AMSR2 89 GHZ
MICROWAVE IMAGERY SHOWS THE SYSTEM HAS ACTIVE CONVECTIVE CLOUD
CLUSTERS AROUND THE CSC.
3.TRACK FORECAST
THE SYSTEM WILL MOVE NORTHWARD ALONG THE PERIPHERY OF A MID-LEVEL
SUB-TROPICAL HIGH UNTIL FT96. THE SYSTEM WILL THEN REMAIN ALMOST
STATIONARY DUE TO WEAK STEERING FLOW UNTIL FT120. THE TRACK
FORECAST IS BASED ON GSM PREDICTIONS, AND REFERENCE TO OTHER NWP
MODELS. TRACK FORECAST CONFIDENCE IS FAIR UNTIL FT48 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, HIGH TCHP, WEAK VWS AND GOOD
UPPER-LEVEL OUTFLOW. THE SYSTEM WILL THEN GRADUALLY WEAKEN UNTIL
FT120 DUE TO THE INFLUENCE OF INTERACTION WITH LOWER SSTS, REDUCED
TCHP AND INCREASED VWS. THE SYSTEM WILL WEAKEN TO TD INTENSITY BY
FT120. THE INTENSITY FORECAST IS BASED ON A CONSENSUS OF GUIDANCE
DATA INCLUDING GSM.
