1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 26SEP24 1200Z, TROPICAL DEPRESSION 18W (CIMARON) WAS 
LOCATED NEAR 28.1N 131.9E, APPROXIMATELY 239 NM EAST-NORTHEAST OF 
KADENA AB, AND HAD TRACKED WEST- NORTHWESTWARD AT 04 KNOTS OVER THE 
PAST SIX HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 25 
KNOTS GUSTING TO 35 KNOTS. SEE REF A (WTPN31 PGTW 261500) FOR FURTHER 
DETAILS.
      (2) AT 26SEP24 1200Z, TROPICAL DEPRESSION 19W (NINETEEN) WAS 
LOCATED NEAR 17.2N 146.8E, APPROXIMATELY 550 NM SOUTHEAST OF IWO TO, 
AND HAD TRACKED NORTHWARD AT 06 KNOTS OVER THE PAST SIX HOURS. MAXIMUM 
SUSTAINED SURFACE WINDS WERE ESTIMATED AT 30 KNOTS GUSTING TO 40 
KNOTS. SEE REF B (WTPN32 PGTW 261500) 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 21.1N 127.4E, APPROXIMATELY 310 NM 
SOUTH OF KADENA AB. ANIMATED ENHANCED INFRARED (EIR) SATELLITE IMAGERY 
AND A 261252Z METOP-B AMSU-B MICROWAVE IMAGE DEPICT A PARTIALLY 
EXPOSED LOW-LEVEL CIRCULATION CENTER (LLCC) WITH PERSISTENT DEEP 
CONVECTION IN THE SOUTHERN SEMICIRCLE WITH FORMATIVE BANDING TO THE 
NORTH. ENVIRONMENTAL ANALYSIS INDICATES THAT INVEST 97W IS IN A 
FAVORABLE ENVIRONMENT FOR DEVELOPMENT WITH WARM (29-30C) SEA SURFACE 
TEMPERATURES, LOW (5-10 KNOTS) VERTICAL WIND SHEAR, AND GOOD 
EQUATORWARD OUTFLOW ALOFT. NUMERICAL MODELS ARE IN GOOD AGREEMENT 
THAT INVEST 97W WILL CONTINUE TRACKING GENERALLY SOUTHWARD AND QUICKLY 
CONSOLIDATE OVER THE NEXT 48 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 
MEDIUM.
      (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 
MEDIUM.//
