1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 29SEP26 0000Z, TROPICAL STORM 25W (SURIGAE) WAS LOCATED NEAR 28.6N 133.9E, APPROXIMATELY 346 NM SOUTHEAST OF SASEBO, JAPAN, AND HAD TRACKED NORTHEASTWARD AT 08 KNOTS OVER THE PAST SIX HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 55 KNOTS GUSTING TO 70 KNOTS. SEE REF A (WTPN31 PGTW 290300) FOR FURTHER DETAILS.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 93W) PREVIOUSLY LOCATED NEAR 15.2N 156.1E IS NOW LOCATED NEAR 15.4N 155.0E, APPROXIMATELY 607 NM EAST-NORTHEAST OF GUAM. ANIMATED MULTISPECTRAL SATELLITE IMAGERY (MSI) DEPICTS A ELONGATED LOW LEVEL CIRCULATION (LLC) WITH PERSISTENT CONVECTION BLOOMING ALONG THE WESTERN PERIPHERY. ENVIRONMENTAL ANALYSIS REVEALS FAVORABLE CONDITIONS FOR DEVELOPMENT WITH LOW (15 KNOTS OR LESS) VERTICAL WIND SHEAR, GOOD POLEWARD OUTFLOW, AND WARM (29 – 30C) SEA SURFACE TEMPERATURES. GLOBAL MODELS DEPICT 93W STEADILY, BUT RATHER SLOWLY, CONSOLIDATING OVER THE NEXT 24-48 HOURS, WHILE TRAVERSING SLOWLY WEST-NORTHWESTWARD.  MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 18 TO 23 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1008 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS REMAINS 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.//
