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:
      (1) AT 18JAN23 0000Z, TROPICAL CYCLONE 09P (NINE) WAS LOCATED NEAR 
17.8S 161.5E, APPROXIMATELY 366 NM NORTHWEST OF NOUMEA, NEW CALEDONIA, AND 
HAD TRACKED EAST- SOUTHEASTWARD AT 11 KNOTS OVER THE PAST SIX HOURS. 
MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 35 KNOTS GUSTING TO 45 
KNOTS. SEE REF A (WTPS31 PGTW 180300) FOR FURTHER DETAILS.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 91P) PREVIOUSLY LOCATED NEAR 
17.3S 159.4E IS NOW THE SUBJECT OF A TROPICAL CYCLONE WARNING. SEE PARA. 
2.A.(1) FOR FURTHER DETAILS. 
      (2) AN AREA OF CONVECTION (INVEST 92P) HAS PERSISTED NEAR 18.6S 
148.8E, APPROXIMATELY 202 NM EAST-SOUTHEAST OF CAIRNS, AUSTRALIA. ANIMATED 
MULTI-SPECTRAL IMAGERY AND A 172032Z SSMIS 37GHZ MICROWAVE PASS SHOW DEEP 
FLARING CONVECTION IN THE SOUTHEAST QUADRANT WRAPPING INTO A PARTIALLY 
EXPOSED AND GRADUALLY CONSOLIDATING LLCC. A 172340Z METOP-B ASCAT PASS 
DEPICTS A 25-30KT WIND FIELD WITHIN THE SOUTHERN SEMI-CIRCLE REVEALING A 
DEFINED CLOSED CIRCULATION. ENVIRONMENTAL ANALYSIS REVEALS FAVORABLE 
CONDITIONS FOR DEVELOPMENT AS INDICATED BY WEAK (15-20KT) VWS, WARM (28-
29C) SEA SURFACE TEMPERATURES, AND GOOD POLEWARD AND EQUATORWARD OUTFLOW. 
GLOBAL MODELS ARE IN AGREEMENT THAT THE 92P WILL BRIEFLY TRACK 
NORTHEASTWARD BEFORE RECURVING EAST-SOUTHEASTWARD AND CONTINUE 
INTENSIFYING. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 27 TO 30 
KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1002 MB. THE 
POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE 
NEXT 24 HOURS IS MEDIUM.
      (3) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
3. JUSTIFICATION FOR REISSUE: UPGRADED AREA IN PARA 2.B.(1) TO WARNING 
STATUS AND ADDED MEDIUM AREA IN PARA 2.B.(2).
