1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 27SEP24 0000Z, TROPICAL DEPRESSION 18W (CIMARON) WAS 
LOCATED NEAR 28.6N 132.1E, APPROXIMATELY 297 NM SOUTH-SOUTHEAST OF 
SASEBO, JAPAN, AND HAD TRACKED NORTHEASTWARD AT 05 KNOTS OVER THE 
PAST SIX HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 25 
KNOTS GUSTING TO 35 KNOTS. SEE REF A (WTPN31 PGTW 270300) FOR THE 
FINAL WARNING ON THIS SYSTEM.
      (2) AT 26SEP24 1800Z, TROPICAL DEPRESSION 19W (NINETEEN) WAS 
LOCATED NEAR 17.8N 146.1E, APPROXIMATELY 498 NM SOUTH-SOUTHEAST OF 
IWO TO, AND HAD TRACKED NORTH-NORTHWESTWARD AT 07 KNOTS OVER THE PAST 
SIX HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 30 KNOTS 
GUSTING TO 40 KNOTS. SEE REF B (WTPN32 PGTW 262100) FOR FURTHER 
DETAILS.
      (3) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 97W) PREVIOUSLY LOCATED NEAR 
24.5N 126.4E IS NOW LOCATED NEAR 20.4N 126.7E, APPROXIMATELY 278 NM 
SOUTH-SOUTHEAST OF ISHIGAKIJIMA. ANIMATED MULTISPECTRAL SATELLITE 
IMAGERY (MSI) DEPICTS A MORE DEFINED AND CONSOLIDATING LOW LEVEL 
CIRCULATION CENTER (LLCC), WITH CONVECTIVE BANDING WRAPPING INTO THE 
CENTER. ENVIRONMENTAL ANALYSIS INDICATES 97W IS IN A FAVORABLE 
ENVIRONMENT FOR DEVELOPMENT DUE TO LOW (5-10 KTS) VERTICAL WIND 
SHEAR, GOOD EQUATORWARD OUTFLOW ALOFT, AND WARM (29-30C) SEA SURFACE 
TEMPERATURES. NUMERICAL MODEL GUIDANCE IS IN AGREEMENT THAT 97W WILL 
CONTINUE TO TRAVERSE SOUTHWARD, NORTHEAST OF LUZON, AND DEEPEN OVER 
THE NEXT 24 HOURS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 
15 TO 20 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 IS UPGRADED TO HIGH. SEE REF C 
(WTPN21 PGTW 270130) 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.
3. JUSTIFICATION FOR REISSUE: UPGRADED AREA IN PARA. 1.B.(1) TO 
HIGH.//
