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 99P) PREVIOUSLY LOCATED NEAR 
13.7S 167.5W IS NOW LOCATED NEAR 12.1S 168.2W, APPROXIMATELY 146 NM 
NORTH-NORTHEAST OF MANUA ISLANDS. ANIMATED ENHANCED MULTISPECTRAL 
SATELLITE IMAGERY DEPICTS DEEP CONVECTION BUILDING OVER THE NORTHERN 
SEMICIRCLE OF A SLOWLY CONSOLIDATING AND VERY BROAD LOW LEVEL 
CIRCULATION CENTER (LLCC). ENVIRONMENTAL ANALYSIS FOR THE AREA INDICATES 
A FAVORABLE ENVIRONMENT WITH WARM SEA SURFACE TEMPERATURES (29-30 C), 
MINIMAL VERTICAL WIND SHEAR (LESS THAN 10 KTS), AND ROBUST POLEWARD 
OUTFLOW ALOFT. GLOBAL DETERMINISTIC AND ENSEMBLE MODELS ARE IN GOOD 
AGREEMENT THAT 99P WILL DEVELOP RAPIDLY OVER THE NEXT 24 HOURS WITH THE 
GFS AND GEFS SHOWING A FASTER DEVELOPMENT. MAXIMUM SUSTAINED SURFACE 
WINDS ARE ESTIMATED AT 23 TO 28 KNOTS. MINIMUM SEA LEVEL PRESSURE IS 
ESTIMATED TO BE NEAR 997 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A 
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS REMAINS HIGH. SEE 
REF A (WTPS21 PGTW 300200) FOR FURTHER DETAILS.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
3. JUSTIFICATION FOR REISSUE: UPDATED INVEST 99P POSITION TO REFLECT 
REISSUED TCFA. //
