1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 28SEP26 1800Z, TYPHOON 25W (SURIGAE) WAS LOCATED NEAR 28.1N 
133.2E, APPROXIMATELY 303 NM EAST-NORTHEAST OF KADENA AB, AND HAD 
TRACKED NORTHEASTWARD AT 09 KNOTS OVER THE PAST SIX HOURS. MAXIMUM 
SUSTAINED SURFACE WINDS WERE ESTIMATED AT 70 KNOTS GUSTING TO 85 KNOTS. 
SEE REF A (WTPN31 PGTW 282100) 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 15.2N 155.5E, APPROXIMATELY 640 NM 
EAST-NORTHEAST OF GUAM. ANIMATED MULTISPECTRAL SATELLITE IMAGERY DEPICTS 
A SPIRAL CONVECTIVE BAND ASSOCIATED WITH A MID-LEVEL CIRCULATION, 
DISPLACED WEST OF A BROAD AND ELONGATED LOW-LEVEL CIRCULATION. 
ENVIRONMENTAL ANALYSIS REVEALS A FAVORABLE ENVIRONMENT FOR DEVELOPMENT 
WITH MODERATE POLEWARD UPPER-LEVEL OUTFLOW, LOW TO MODERATE VERTICAL 
WINDSHEAR (15-20 KTS), AND WARM SEA SURFACE TEMPERATURES (29-30 C).  
GLOBAL MODELS AND ENSEMBLE SYSTEMS SHOW 92W SLOWLY CONSOLIDATING OVER 
THE NEXT 48 HOURS AS THE SYSTEM TRAVELS WESTWARD. NAVGEM IS THE MOST 
AGGRESSIVE OF THE DETERMINISTIC MODELS WITH GFS NOT FAR BEHIND. MAXIMUM 
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 18 TO 23 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 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.//
