1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 04OCT26 0600Z, TYPHOON 26W (CHOI-WAN) WAS LOCATED NEAR 
22.9N 147.0E, APPROXIMATELY 333 NM EAST-SOUTHEAST OF IWO TO, AND HAD 
TRACKED NORTHWARD AT 08 KNOTS OVER THE PAST SIX HOURS. MAXIMUM 
SUSTAINED SURFACE WINDS WERE ESTIMATED AT 125 KNOTS GUSTING TO 150 
KNOTS. SEE REF A (WTPN32 PGTW 040900) FOR FURTHER DETAILS.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 94W) PREVIOUSLY LOCATED NEAR 
8.1N 167.9E IS NOW LOCATED NEAR 9.3N 167.1E, APPROXIMATELY 51 NM 
NORTHWEST OF KWAJALEIN. ANIMATED ENHANCED INFRARED (EIR) SATELLITE 
IMAGERY DEPICTS 94W AS A SLOWLY CONSOLIDATING LOW LEVEL CIRCULATION 
CENTER (LLCC) WITH CONVECTION BUILDING NEAR THE CENTER. A 030910Z 
ASCAT-B PASS REVEALED A BAND OF 15-20 KNOT WINDS WRAPPING AROUND THE 
NORTHEN PERIPHERY OF THE CIRCULATION. ENVIRONMENTAL ANALYSIS REVEALS 
MARGINALLY FAVORABLE CONDITIONS FOR DEVELOPMENT WITH LOW TO MODERATE 
VERTICAL WIND SHEAR (15-20 KTS), WEAK EQUATORWARD OUTFLOW ALOFT, AND 
WARM (29-30 C) SEA SURFACE TEMPERATURES. GLOBAL MODELS ARE IN FAIR 
AGREEMENT THAT 94W WILL BE QUASI-STATIONARY OVER THE NEXT 24 HOURS AS 
IT CONTINUES TO CONSOLIDATE. MAXIMUM SUSTAINED SURFACE WINDS ARE 
ESTIMATED AT 18 TO 23 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.
      (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.//
