1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 96W) PREVIOUSLY LOCATED 
NEAR 6.2N 127.2E IS NOW LOCATED NEAR 6.7N 127.3E, APPROXIMATELY 103 NM 
EAST-SOUTHEAST OF DAVAO. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY 
DEPICTS A BROAD, SLOWLY CONSOLIDATING LOW LEVEL CIRCULATION. A 170923Z 
SSMIS 91GHZ MICROWAVE IMAGE SHOWS FRAGMENTED FORMATIVE BANDING 
BEGINNING TO ORGANIZE AROUND THE LOW LEVEL CIRCULATION CENTER. 
ENVIRONMENTAL ANALYSIS REVEALS THAT INVEST 96W IS IN A FAVORABLE 
ENVIRONMENT FOR FURTHER DEVELOPMENT, WITH WARM (28-29C) SEA SURFACE 
TEMPERATURES, GOOD POLEWARD OUTFLOW ALOFT, AND LOW TO MODERATE (15-20 
KTS) VERTICAL WIND SHEAR. GLOBAL MODELS ARE IN GOOD AGREEMENT THAT 
INVEST 96W WILL GENERALLY TRACK NORTHWARD OVER THE NEXT 48 HOURS AS 
THE SYSTEM STEERS CLOSER TO THE PHILIPPINES. MAXIMUM SUSTAINED SURFACE 
WINDS ARE ESTIMATED AT 20 TO 25 KNOTS. MINIMUM SEA LEVEL PRESSURE IS 
ESTIMATED TO BE NEAR 1004 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A 
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS REMAINS HIGH.  
SEE REF A (WTPN21 PGTW 171500) FOR FURTHER INFORMATION.
      (2) NO OTHER SUSPECT AREAS.
   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: NONE.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
3. JUSTIFICATION FOR REISSUE: UPDATED INFORMATION IN PARA 1.B.(1) DUE 
TO REISSUED TCFA.//
