1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 30AUG25 1200Z, TROPICAL DEPRESSION 20W (NONGFA) WAS LOCATED 
NEAR 18.0N 104.4E, APPROXIMATELY 199 NM SOUTH-SOUTHWEST OF HANOI, 
VIETNAM, AND HAD TRACKED WESTWARD AT 21 KNOTS OVER THE PAST SIX HOURS. 
MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 25 KNOTS GUSTING TO 35 
KNOTS. SEE REF A (WTPN31 PGTW 301500) FOR THE FINAL WARNING ON THIS 
SYSTEM.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) AN AREA OF CONVECTION (INVEST 95W) HAS PERSISTED NEAR 10.4N 
133.2E, APPROXIMATELY 204 NM NORTH-NORTHWEST OF PALAU. ANIMATED ENHANCED 
INFRARED SATELLITE IMAGERY (EIR) DEPICTS FLARING CONVECTION ALONG THE 
SOUTH-SOUTHEASTERN PERIPHERY OF THE POORLY ORGANIZED CIRCULATION CENTER 
(LLCC).  A 301213Z ASCAT IMAGE REVEALS 15-20 KNOT WINDS TO THE SOUTHWEST 
PERIPHERY OF 93W. ENVIRONMENTAL ANALYSIS FOR THE AREA INDICATES 
FAVORABLE CONDITIONS FOR DEVELOPMENT WITH LOW VERTICAL WIND SHEAR (10-15 
KTS), WARM SEA SURFACE TEMPERATURES (30-31 C), AND MODERATE EQUATORWARD 
OUTFLOW ALOFT. GLOBAL DETERMINISTIC MODELS ARE IN FAIR AGREEMENT THAT 
95W HAS A CHANCE FOR DEVELOPMENT IN THE NEXT 48 HOURS TRACKING NORTH, 
WITH GFS BEING THE MORE AGGRESSIVE. ENSEMBLE MODELS ARE IN AGREEMENT AS 
WELL FOR A NORTHERN TRACK WITH GEFS BEING THE MORE AGGRESSIVE. MAXIMUM 
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 13 TO 18 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 LOW.
      (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: ADDED LOW AREA IN PARA. 1.B.(1).//
