1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY: NONE.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
2. SOUTH PACIFIC AREA (WEST COAST OF SOUTH AMERICA TO 135 EAST):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 92P) PREVIOUSLY LOCATED NEAR 
16.7S 151.7E IS NOW LOCATED NEAR 17.7S 155.7E, APPROXIMATELY 234 NM 
EAST OF LIHOU REEF. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY 
DEPICTS AN ELONGATED, POORLY ORGANIZED LOW-LEVEL CIRCULATION (LLC) 
WITH A LINEAR BAND OF DEEP CONVECTION. A 191102Z ASCAT-C BULLSEYE 
IMAGE INDICATES A TROUGH-LIKE WIND FIELD WITH EXTENSIVE SWATH OF 25-
30 KNOT WINDS OVER THE NORTHERN SEMICIRCLE AND PATCHY AREAS OF 25 
KNOT WINDS OVER THE SOUTHERN SEMICIRCLE. AS REVEALED IN A 191504Z 
AMSR2 89GHZ MICROWAVE IMAGE, THE SYSTEM IS STRUGGLING TO CONSOLIDATE 
WITH DEEP CONVECTION PERSISTING ALONG THE TROUGH BUT LITTLE EVIDENCE 
OF A DISCRETE LLC. HOWEVER, THE OVERALL WIND FIELD HAS STRENGTHENED 
AROUND THE PERIPHERY OF THE SYSTEM. ENVIRONMENTAL CONDITIONS REMAIN 
MARGINAL WITH DIFFLUENT SUBTROPICAL WESTERLIES OVER THE SYSTEM, 
MODERATE TO HIGH VERTICAL WIND SHEAR AND WARM SST (28-29C). DESPITE 
THE MARGINAL ENVIRONMENT, GLOBAL MODELS CONTINUE TO STRENGTHEN THE 
WINDS TO GALE-FORCE STRENGTH WITHIN THE NEXT DAY AS THE SYSTEM TRACKS 
EAST-SOUTHEASTWARD TOWARD NEW CALEDONIA. MAXIMUM SUSTAINED SURFACE 
WINDS ARE ESTIMATED AT 25 TO 30 KNOTS. MINIMUM SEA LEVEL PRESSURE IS 
ESTIMATED TO BE NEAR 999 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A 
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS REMAINS HIGH. 
SEE REF A (WTPS21 PGTW 190200) FOR FURTHER DETAILS.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: 
      (1) THE AREA OF CONVECTION (REMNANTS 09P) PREVIOUSLY LOCATED 
NEAR 22.1S 171.7E IS NOW LOCATED NEAR 24.6S 176.1E, APPROXIMATELY 392 
NM SOUTH OF FIJI. THE SYSTEM IS CURRENTLY CLASSIFIED AS A SUBTROPICAL 
STORM, GENERALLY CHARACTERIZED AS HAVING BOTH TROPICAL AND MID-
LATITUDE CYCLONE FEATURES. 09P IS LOCATED UNDER STRONG NORTHWESTERLY 
FLOW ALONG THE LEADING EDGE OF A DEEP SUBTROPICAL SHORTWAVE TROUGH 
WITH 30-40 KNOTS OF VERTICAL WIND SHEAR. CONSEQUENTLY, ANIMATED 
ENHANCED INFRARED SATELLITE IMAGERY AND A 191647Z SSMIS 91GHZ COLOR 
COMPOSITE MICROWAVE IMAGE DEPICT A HIGHLY ASYMMETRIC STRUCTURE WITH A 
VERY BROAD, POORLY DEFINED LOW-LEVEL CIRCULATION CENTER AND DEEP 
CONVECTION SHEARED TO THE SOUTHEAST. GLOBAL MODELS INDICATE THIS 
SUBTROPICAL STORM WILL RAPIDLY TRACK SOUTH-SOUTHEASTWARD AND STEADILY 
WEAKEN OVER THE NEXT 12-24 HOURS. THE SYSTEM WILL BE CLOSELY 
MONITORED FOR SIGNS OF REGENERATION. FOR HAZARDS AND WARNINGS, 
REFERENCE THE FLEET WEATHER CENTER SAN DIEGO HIGH WINDS AND SEAS 
PRODUCT OR REFER TO LOCAL WMO DESIGNATED FORECAST AUTHORITY. THE 
POTENTIAL FOR THE SYSTEM TO TRANSITION INTO A SIGNIFICANT TROPICAL 
CYCLONE WITHIN THE NEXT 24 HOURS REMAINS LOW.
      (2) NO OTHER SUBTROPICAL SYSTEMS. 
3. JUSTIFICATION FOR REISSUE: REMOVED TC 09P FINAL WARNING 
INFORMATION AND CORRECTED NUMEROUS ERRORS. ADDITIONALLY, MOVED INVEST 
92P TO THE TROPICAL DISTURBANCE SUMMARY SECTION (2.B.(1)) AND UPDATED 
THE INFORMATION.//
