1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 19SEP24 0600Z, TROPICAL DEPRESSION 16W (SOULIK) WAS 
LOCATED NEAR 16.9N 106.9E, APPROXIMATELY 97 NM NORTHWEST OF DA NANG, 
VIETNAM, AND HAD TRACKED WESTWARD AT 11 KNOTS OVER THE PAST SIX HOURS. 
MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 30 KNOTS GUSTING TO 
40 KNOTS. SEE REF A (WTPN31 PGTW 190900) FOR THE FINAL WARNING ON THIS 
SYSTEM.
      (2) AT 19SEP24 1200Z, TROPICAL DEPRESSION 15W (PULASAN) WAS 
LOCATED NEAR 30.5N 122.0E, APPROXIMATELY 49 NM SOUTH-SOUTHEAST OF 
SHANGHAI, CHINA, AND HAD TRACKED NORTHWESTWARD AT 13 KNOTS OVER THE 
PAST SIX HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 30 
KNOTS GUSTING TO 40 KNOTS. SEE REF B (WTPN32 PGTW 191500) FOR FURTHER 
DETAILS.
      (3) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) AN AREA OF CONVECTION (INVEST 90W) HAS PERSISTED NEAR 20.1N 
129.0E, APPROXIMATELY 507 NM SOUTHEAST OF TAIPEI, TAIWAN. ANIMATED 
ENHANCED INFRARED SATELLITE IMAGERY DEPICTS FORMATIVE BANDING OVER THE 
SOUTHERN AND EASTERN QUADRANTS OF AN ELONGATED LOW-LEVEL CIRCULATION 
CENTER (LLCC). A 191250Z MHS 89 GHZ MICROWAVE IMAGE REVEALS A WEAKLY 
DEFINED CENTER, WITH THE CONVECTION PRIMARILY OVER THE EASTERN 
SEMICIRCLE. A RECENT PARTIAL SCATTEROMETER IMAGE SHOWS SHARP CYCLONIC 
TURNING AND A POSSIBLE ELONGATED CIRCULATION ADJACENT TO AN EXTENSIVE 
SWATH OF 20-30 KNOT SOUTHERLY WINDS, WHICH COULD BE AIDING IN THE 
DISTURBANCE'S SPIN-UP. ENVIRONMENTAL CONDITIONS ARE MARGINALLY 
FAVORABLE WITH LOW TO MODERATE (15 TO 20 KNOTS) VERTICAL WIND SHEAR 
OFFSET BY BROAD DIFFLUENCE ALOFT. GFS IS THE MOST AGGRESSIVE MODEL AT 
THIS TIME INDICATING A WEST-NORTHWESTWARD TRACK TOWARD TAIWAN, WITH 
STEADY DEVELOPMENT OVER THE NEXT 36 HOURS. MAXIMUM SUSTAINED SURFACE 
WINDS ARE ESTIMATED AT 12 TO 18 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 IS LOW.
      (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: ADDED LOW AREA IN PARA. 1.B.(1).//
