1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 26AUG23 1200Z, TYPHOON 09W (SAOLA) WAS LOCATED NEAR 17.5N 
123.1E, APPROXIMATELY 212 NM NORTHEAST OF MANILA, PHILIPPINES, AND HAD 
TRACKED SOUTHWARD AT 05 KNOTS OVER THE PAST SIX HOURS. MAXIMUM 
SUSTAINED SURFACE WINDS WERE ESTIMATED AT 110 KNOTS GUSTING TO 135 
KNOTS. SEE REF B (WTPN32 PGTW 261500) FOR FURTHER DETAILS.
      (2) AT 26AUG23 1200Z, TROPICAL STORM 08W (DAMREY) WAS LOCATED 
NEAR 28.0N 151.1E, APPROXIMATELY 728 NM SOUTHEAST OF YOKOSUKA, JAPAN, 
AND HAD TRACKED NORTHWESTWARD AT 25 KNOTS OVER THE PAST SIX HOURS. 
MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 50 KNOTS GUSTING TO 
65 KNOTS. SEE REF A (WTPN31 PGTW 261500) FOR FURTHER DETAILS.
      (3) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 93W) PREVIOUSLY LOCATED NEAR 
15.5N 143.3E IS NOW LOCATED NEAR 16.3N 143.1E, APPROXIMATELY 198 NM 
NORTH-NORTHWEST OF GUAM. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY 
AND A 261521Z ATMS 88.2 GHZ PASS DEPICT A SLOWLY CONSOLIDATING LOW 
LEVEL CIRCULATION WITH A CURVED DEEP CONVECTIVE BAND IN THE NORTHERN 
SEMICIRCLE. A 261220Z ASCAT-C PASS REVEALS AN ELONGATED, DEFINED 
CIRCULATION WITH 15-20 KT WINDS TO THE WEST AND 20-25 KT, CONVERGENT, 
MONSOONAL WESTERLIES DISPLACED TO THE SOUTH OF THE SYSTEM. 
ENVIRONMENTAL ANALYSIS REVEALS FAVORABLE CONDITIONS FOR DEVELOPMENT 
WITH WARM (29-30 C) SST, LOW (5-10 KTS) VERTICAL WIND SHEAR, AND 
ROBUST POLEWARD OUTFLOW ALOFT. GLOBAL MODELS INDICATE 93W WILL TRACK 
SLOWLY EASTWARD WITH STEADY DEVELOPMENT OVER THE NEXT 48 HOURS. THE 
SYSTEM WILL LIKELY STALL OVER OR TO THE WEST OF THE NORTHERN MARIANAS 
WITH STRONG MONSOONAL FLOW PERSISTING OVER THE REGION. MAXIMUM 
SUSTAINED SURFACE WINDS ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA 
LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1000 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.//
