1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 03SEP26 0000Z, TROPICAL STORM 17W (SAUDEL) FINAL WAS 
LOCATED NEAR 23.8N 117.4E, APPROXIMATELY 198 NM EAST-NORTHEAST OF HONG 
KONG, AND HAD TRACKED WEST-NORTHWESTWARD AT 10 KNOTS OVER THE PAST SIX 
HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 40 KNOTS 
GUSTING TO 50 KNOTS. SEE REF A (WTPN32 PGTW 030300) FOR THE FINAL 
WARNING ON THIS SYSTEM.
      (2) AT 03SEP26 0600Z, TROPICAL STORM 22W (KROVANH) WAS LOCATED 
NEAR 27.0N 129.0E, APPROXIMATELY 71 NM EAST-NORTHEAST OF KADENA AB, 
AND HAD TRACKED NORTHWESTWARD AT 13 KNOTS OVER THE PAST SIX HOURS. 
MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 40 KNOTS GUSTING TO 
50 KNOTS. SEE REF B (WTPN31 PGTW 030900) FOR FURTHER DETAILS.
      (3) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 97W) PREVIOUSLY LOCATED NEAR 
15.3N 140.8E IS NOW LOCATED NEAR 15.8N 140.3E, APPROXIMATELY 293 NM 
WEST-NORTHWEST OF GUAM. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY 
(EIR) REVEALS A POORLY DEFINED LOW-LEVEL CIRCULATION CENTER (LLCC) 
OBSCURED BY MID- AND HIGH-LEVEL CLOUDS. DEEP CONVECTION HAS PERSISTED 
FOR SEVERAL HOURS IN THE NORTHWESTERN QUADRANT ASSOCIATED WITH 97W, 
REFLECTING AN IMPROVED CONVECTIVE SIGNATURE. A 030005Z METOP-B ASCAT 
PASS SHOWS A CLOSED SURFACE CIRCULATION WITH 20 KT WINDS ALONG THE 
WESTERN AND SOUTHERN PERIPHERY. MORE RECENT SCATTEROMETRY DATA 
INDICATE THAT THE LLCC IS ELONGATED, AND ELEVATED WINDS NOW SPAN TWO-
THIRDS OF THE WAY AROUND THE LLCC. OVERALL ENVIRONMENTAL CONDITIONS 
ARE ASSESSED AS MARGINALLY FAVORABLE WITH MODERATE (20-25 KTS) 
VERTICAL WIND SHEAR, VERY WARM (29-30 C) SEA SURFACE TEMPERATURES, 
IMPROVING EQUATORWARD UPPER-LEVEL OUTFLOW, AND A ROBUST AMOUNT OF 
MOISTURE IN THE AREA. GLOBAL MODELS ARE RELATIVELY CONSERVATIVE WITH 
DEVELOPMENT ON 97W, WITH DETERMINISTIC MODELS MAINTAINING A BROAD 
CIRCULATION THAT SLIGHTLY CONSOLIDATES OVER THE NEXT 24 HOURS WHILE 
TRANSITING NORTHWESTWARD. MAXIMUM SUSTAINED SURFACE WINDS ARE 
ESTIMATED AT 18 TO 23 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED 
TO BE NEAR 1005 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.//
