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 
13.9N 131.5E IS NOW LOCATED NEAR 13.8N 131.0E, APPROXIMATELY 423 NM EAST 
OF LEGAZPI, PHILIPPINES. ANIMATED MULTISPECTRAL SATELLITE IMAGERY (MSI) 
DEPICTS A CONSOLIDATING LOW-LEVEL CIRCULATION CENTER (LLCC) EMBEDDED 
WITHIN PERSISTENT CONVECTION. ENVIRONMENTAL ANALYSIS REVEALS MARGINALLY 
FAVORABLE CONDITIONS FOR DEVELOPMENT WITH GOOD RADIAL OUTFLOW, WARM SEA 
SURFACE TEMPERATURES (30-31 C), AND LOW NORTHWESTERLY VERTICAL WIND 
SHEAR (10-15 KTS). GLOBAL DETERMINISTIC AND ENSEMBLE MODELS ARE IN GOOD 
AGREEMENT THAT INVEST 96W WILL STEADILY CONSOLIDATE OVER THE NEXT 24 
HOURS WHILE TRACKING NORTHWESTWARD. MAXIMUM SUSTAINED SURFACE WINDS ARE 
ESTIMATED AT 18 TO 23 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO 
BE NEAR 1007 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT 
TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS REMAINS HIGH.SEE REF A 
(WTPN21 PGTW 170300) FOR FURTHER DETAILS.
      (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.//
