1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 04OCT26 0000Z, TYPHOON 26W (CHOI-WAN) WAS LOCATED NEAR 
22.1N 147.1E, APPROXIMATELY 358 NM EAST-SOUTHEAST OF IWO TO, AND HAD 
TRACKED NORTH-NORTHEASTWARD AT 14 KNOTS OVER THE PAST SIX HOURS. MAXIMUM 
SUSTAINED SURFACE WINDS WERE ESTIMATED AT 110 KNOTS GUSTING TO 135 
KNOTS. SEE REF A (WTPN32 PGTW 040300) 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 9.4N 167.3E, APPROXIMATELY 49 NM NORTH-
NORTHWEST OF KWAJALEIN. ANIMATED ENHANCED INFRARED (EIR) SATELLITE 
IMAGERY DEPICTS 94W WITH A CONSOLIDATING LOW-LEVEL CIRCULATION CENTER 
THAT HAS TUCKED UNDERNEATH THE SOUTHEASTERN QUADRANT OF PERSISTENT 
CONVECTION. 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 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.//
