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 96P) PREVIOUSLY LOCATED NEAR 
13.3S 159.1E IS NOW LOCATED NEAR 13.1S 156.8E, APPROXIMATELY 286 NM 
SOUTHWEST OF HONIARA. ENHANCED INFRARED SATELLITE IMAGERY DEPICTS A 
CONSOLIDATING CIRCULATION WITH PERSISTENT CONVECTION OBSCURING THE LOW-
LEVEL CIRCULATION CENTER (LLCC). A 161339Z OCEANSAT-3 PASS REVEALS 25-
30KTS WINDS ALONG THE NORTHEASTERN PERIPHERY OF THE CIRCULATION. 
ENVIRONMENTAL ANALYSIS DEPICTS FAVORABLE CONDITIONS FOR DEVELOPMENT WITH 
LOW TO MODERATE VERTICAL WIND SHEAR (15 TO 20KTS), WARM SEA SURFACE 
TEMPERATURES (28 TO 29C), AND GOOD POLEWARD OUTFLOW. GLOBAL 
DETERMINISTIC MODELS AND ENSEMBLE MODELS ARE IN GOOD AGREEMENT OF 96P 
TAKING A GENERALLY WESTWARD TRACK AND ITS DEVELOPMENT IN A TROPICAL 
CYCLONE THE NEXT 24 HOURS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED 
AT 28 TO 33 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 
1003 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL 
CYCLONE WITHIN THE NEXT 24 HOURS IS UPGRADED TO HIGH. SEE REF A (WTPS21 
PGTW 161830) FOR FURTHER DETAILS.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
3. JUSTIFICATION FOR REISSUE: UPGRADED AREA IN PARA. 2.B.(1) TO HIGH.//
