1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 27AUG23 0000Z, TROPICAL STORM 08W (DAMREY) WAS LOCATED NEAR 
31.5N 147.6E, APPROXIMATELY 456 NM EAST-SOUTHEAST OF YOKOSUKA, JAPAN, AND 
HAD TRACKED NORTHWESTWARD AT 27 KNOTS OVER THE PAST SIX HOURS. MAXIMUM 
SUSTAINED SURFACE WINDS WERE ESTIMATED AT 55 KNOTS GUSTING TO 70 KNOTS. 
SEE REF A (WTPN31 PGTW 270300) FOR FURTHER DETAILS. 
      (2) AT 27AUG23 0000Z, TYPHOON 09W (SAOLA) WAS LOCATED NEAR 16.8N 
123.0E, APPROXIMATELY 175 NM NORTHEAST OF MANILA, PHILIPPINES, AND HAD 
TRACKED SOUTHWARD AT 03 KNOTS OVER THE PAST SIX HOURS. MAXIMUM SUSTAINED 
SURFACE WINDS WERE ESTIMATED AT 115 KNOTS GUSTING TO 140 KNOTS. SEE REF B 
(WTPN32 PGTW 270300) 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 16.4N 143.5E, APPROXIMATELY 192 NM 
NORTH-NORTHWEST OF GUAM. ANIMATED MULTISPECTRAL SATELLITE IMAGERY DEPICTS 
A BROAD AREA OF SHARP TROUGHING WITH PERSISTENT, DEEP CONVECTIVE BANDING. 
ENVIRONMENTAL ANALYSIS REVEALS FAVORABLE CONDITIONS FOR DEVELOPMENT WITH 
WARM (29-30 C) SST, LOW (10-15 KTS) VERTICAL WIND SHEAR, AND ROBUST 
POLEWARD OUTFLOW ALOFT. GLOBAL MODELS INDICATE 93W WILL TRACK SLOWLY 
WESTWARD WITH STEADY DEVELOPMENT OVER THE NEXT 48 HOURS. THE SYSTEM WILL 
LIKELY STALL NEAR 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 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.//
