REMARKS:
222100Z POSITION NEAR 36.3N 132.9E.
22SEP19. TROPICAL STORM 18W (TAPAH), LOCATED APPROXIMATELY 72 NM
NORTH-NORTHWEST OF IWAKUNI, JAPAN, HAS TRACKED NORTHEASTWARD AT
24 KNOTS OVER THE PAST SIX HOURS. TS 18W HAS CURRENTLY UNDERGOING
EXTRA-TROPICAL TRANSITION (ETT) AND IS RAPIDLY ACCELERATING
NORTHEASTWARD WITHIN THE MIDLATITUDE SOUTHWESTERLIES. THE SYSTEM HAS
BEGUN TO DISPLAY FRONTAL CHARACTERISTICS IN SATELLITE IMAGERY
SUGGESTING THAT IT WILL SOON BE AN EXTRA-TROPICAL SYSTEM. ANIMATED
ENHANCED INFRARED SATELLITE DEPICTS A WEAK, ELONGATED LOW-LEVEL
CIRCULATION (LLC) WITH DEEP CONVECTION SHEARED TO THE NORTHEAST. A
221711Z AMSR2 36 GHZ MICROWAVE IMAGE SHOWS EXTENSIVE DEEP CONVECTION
WITH FRONTAL CHARACTERISTICS HOWEVER, THERE IS NO LCC EVIDENT. THE
INITIAL POSITION IS BASED ON THE IR LOOP AND THE JMA RADAR LOOP. THE
OVERALL CONFIDENCE IN THE INITIAL POSITION IS LOW DUE TO THE
ELONGATED NATURE AND WEAK SIGNATURE OF THE LCC. THE INITIAL
INTENSITY OF 55 KNOTS WAS BASED ON AN EARLIER ASCAT IMAGE AND
SUPPORTED BY BOTH A PGTW EXTRA-TROPICAL SATELLITE FIX OF T3.5 (55
KNOTS) AND A RECENT SATCON ESTIMATE OF 53 KNOTS. ENVIRONMENTAL
CONDITIONS ARE BECOMING INCREASINGLY UNFAVORABLE. THE SYSTEM IS
CURRENTLY IN AN AREA OF HIGH (30-40 KNOT) VERTICAL WIND SHEAR AND IS
TRACKING OVER COOLER (25-26 CELSIUS) SEA SURFACE TEMPERATURES. THE
POOR ENVIRONMENT IS OFFSET BY STRONG POLEWARD OUTFLOW. TS TAPAH IS
TRACKING NORTHEASTWARD ALONG THE NORTHWEST PERIPHERY OF THE
SUBTROPICAL RIDGE (STR) LOCATED TO THE SOUTHEAST. THE SYSTEM IS
FORECAST TO TRACK TO THE NORTHEAST FOR THE DURATION OF THE FORECAST.
THE SYSTEM WILL CONTINUE TO EXPERIENCE A DEGRADING ENVIRONMENT WHICH
WILL CAUSE A WEAKENING TREND AS EXTRATROPICAL TRANSITION OCCURS. TS
18W WILL COMPLETE ETT BY TAU 12 AND CONTINUE TO ACCELERATE
NORTHEASTWARD, EVENTUALLY MAKING LANDFALL ON NORTHERN HONSHU AND
HOKKAIDO AFTER TAU 12. THE SYSTEM IS FORECAST TO REMAIN A STRONG
COLD-CORE LOW WITH GALE-FORCE WINDS ANTICIPATED OVER NORTHERN
HONSHU. DYNAMIC MODEL GUIDANCE REMAINS IN STRONG AGREEMENT THROUGH
TAU 24 LENDING HIGH CONFIDENCE IN THE OFFICIAL JTWC FORECAST TRACK.
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 221800Z
IS 26 FEET.//

RSMC TROPICAL CYCLONE PROGNOSTIC REASONING
REASONING NO.16 FOR TY 1917 TAPAH (1917)
1.GENERAL COMMENTS
TY TAPAH IS LOCATED AT 29.5N, 126.1E. INFORMATION ON THE CURRENT
POSITION IS BASED ON ANIMATED MSI AND SURFACE OBSERVATIONS.
POSITIONAL ACCURACY IS FAIR. CENTRAL PRESSURE IS 970HPA AND
MAXIMUM SUSTAINED WINDS IS 65KNOTS. THE SYSTEM IS IN A NEUTRAL
ENVIRONMENT FOR DEVELOPMENT UNDER THE INFLUENCE OF 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 SURFACE OBSERVATIONS.
2.SYNOPTIC SITUATION
THE SYSTEM IS MOVING NORTH-NORTHEASTWARD 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. 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 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 WEAKEN UNTIL FT12 DUE TO THE INFLUENCE OF
INCREASED VWS. THE SYSTEM WILL THEN MAINTAIN ITS INTENSITY UNTIL

WTPQ30 RJTD 201800 RRA
RSMC TROPICAL CYCLONE PROGNOSTIC REASONING
REASONING NO.12 FOR STS 1917 TAPAH (1917)
1.GENERAL COMMENTS
STS TAPAH IS LOCATED AT 25.0N, 126.3E. 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 IS 60KNOTS. THE SYSTEM IS
IN A FAVORABLE ENVIRONMENT FOR DEVELOPMENT UNDER THE INFLUENCE OF
HIGH SSTS AND HIGH TCHP. 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-NORTHWESTWARD 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. WATER VAPOR IMAGERY SHOWS DRY AIR AROUND THE SYSTEM.
3.TRACK FORECAST
THE SYSTEM WILL GRADUALLY DECELERATE AND MOVE NORTH-NORTHWESTWARD
ALONG THE PERIPHERY OF A MID-LEVEL SUB-TROPICAL HIGH UNTIL FT12.
THE SYSTEM WILL THEN GRADUALLY DECELERATE AND MOVE NORTHWARD 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
SYSTEM WILL THEN GRADUALLY ACCELERATE AND 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 FAIR UNTIL FT48 BUT

WTPQ30 RJTD 200000 RRA
RSMC TROPICAL CYCLONE PROGNOSTIC REASONING
REASONING NO. 9 FOR TS 1917 TAPAH (1917)
1.GENERAL COMMENTS
TS TAPAH IS LOCATED AT 22.8N, 127.0E. INFORMATION ON THE CURRENT
POSITION IS BASED ON ANIMATED MSI AND SURFACE OBSERVATIONS.
POSITIONAL ACCURACY IS FAIR. CENTRAL PRESSURE IS 990HPA AND
MAXIMUM SUSTAINED WINDS IS 40KNOTS. THE SYSTEM IS IN A NEUTRAL
ENVIRONMENT FOR DEVELOPMENT UNDER THE INFLUENCE OF HIGH SSTS, 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 SURFACE WINDS
DATA ESTIMATED FROM SATELLITE SCATTEROMETERS AND SURFACE
OBSERVATIONS.
2.SYNOPTIC SITUATION
THE SYSTEM IS MOVING WEST-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. 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 GRADUALLY TURN TO THE NORTH ALONG THE PERIPHERY OF
A MID-LEVEL SUB-TROPICAL HIGH UNTIL FT48. THE SYSTEM WILL THEN
GRADUALLY ACCELERATE AND MOVE NORTH-NORTHEASTWARD UNDER THE
INFLUENCE OF A MID-LATITUDE TROUGH UNTIL FT72. THE SYSTEM WILL
THEN MOVE NORTHEASTWARD UNTIL FT96. 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.

WTPQ30 RJTD 191200 RRA
RSMC TROPICAL CYCLONE PROGNOSTIC REASONING
REASONING NO. 7 FOR TS 1917 TAPAH (1917)
1.GENERAL COMMENTS
TS TAPAH IS LOCATED AT 23.0N, 128.2E. 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 IS 35KNOTS. THE SYSTEM IS
IN A FAVORABLE ENVIRONMENT FOR DEVELOPMENT UNDER THE INFLUENCE OF
HIGH SSTS, HIGH TCHP AND WEAK VWS. 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 BETWEEN TWO MID-LEVEL
SUB-TROPICAL HIGHS. ANIMATED MSI SHOWS CB CLUSTERS GATHERING
AROUND THE CSC. WATER VAPOR IMAGERY SHOWS DRY AIR IN THE DIRECTION
OF THE MOVEMENT.
3.TRACK FORECAST
THE SYSTEM WILL MOVE WEST-NORTHWESTWARD ALONG THE PERIPHERY OF A
MID-LEVEL SUB-TROPICAL HIGH UNTIL FT24. THE SYSTEM WILL THEN
GRADUALLY TURN TO THE NORTH UNTIL FT48. THE SYSTEM WILL THEN MOVE
NORTHEASTWARD UNDER THE INFLUENCE OF A MID-LATITUDE TROUGH UNTIL
FT96. 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 DEVELOP UNTIL FT60 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
FT96 IN A STATE OF EXTRATROPICAL TRANSITION. THE SYSTEM WILL
