1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 22SEP24 0600Z, TROPICAL DEPRESSION 17W (SEVENTEEN) WAS 
LOCATED NEAR 24.9N 118.5E, APPROXIMATELY 164 NM WEST OF TAIPEI, TAIWAN, 
AND HAD TRACKED WESTWARD AT 12 KNOTS OVER THE PAST SIX HOURS. MAXIMUM 
SUSTAINED SURFACE WINDS WERE ESTIMATED AT 25 KNOTS GUSTING TO 35 KNOTS. 
SEE REF A (WTPN31 PGTW 220900) FOR THE FINAL WARNING ON THIS SYSTEM.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) AN AREA OF CONVECTION (INVEST 93W) HAS PERSISTED NEAR 18.3N 
107.3E, APPROXIMATELY 146 NM NORTHWEST OF DA NANG, VIETNAM. ANIMATED 
MULTISPECTRAL SATELLITE IMAGERY (MSI) AND A 222316Z F-17 SSMIS 91GHZ 
MICROWAVE IMAGE DEPICT A POORLY-ORGANIZED LOW LEVEL CIRCULATION (LLC), 
WITH DEEP FLARING CONVECTION COMPLETELY OBSCURING THE LLC. ENVIRONMENTAL 
ANALYSIS INDICATES 93W IS IN A MARGINAL ENVIRONMENT FOR DEVELOPMENT DUE 
TO WARM (28-29C) SEA SURFACE TEMPERATURES AND GOOD EQUATORWARD OUTFLOW 
ALOFT OFFSET BY HIGH VERTICAL WIND SHEAR. NUMERICAL MODELS ARE IN 
AGREEMENT ON QUICK CONSOLIDATION OVER THE NEXT 24 HOURS AS THE SYSTEM 
TRACKS NORTHEASTWARD TOWARD HAINAN. HOWEVER, THE MARGINAL ENVIRONMENT 
MAY INHIBIT DEVELOPMENT OF 93W. MAXIMUM SUSTAINED SURFACE WINDS ARE 
ESTIMATED AT 18 TO 23 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 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).//
