1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1)  AT 28AUG23 0600Z, TROPICAL STORM 08W (DAMREY) WAS LOCATED 
NEAR 39.9N 145.6E, APPROXIMATELY 204 NM EAST OF MISAWA, JAPAN, AND HAD 
TRACKED NORTH-NORTHEASTWARD AT 17 KNOTS OVER THE PAST SIX HOURS. 
MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 45 KNOTS GUSTING TO 
55 KNOTS. SEE REF A (WTPN31 PGTW 280900) FOR THE FINAL WARNING ON THIS 
SYSTEM.
      (2) AT 28AUG23 0600Z, TYPHOON 09W (SAOLA) WAS LOCATED NEAR 17.5N 
124.3E, APPROXIMATELY 258 NM NORTHEAST OF MANILA, PHILIPPINES, AND HAD 
TRACKED NORTHWARD AT 07 KNOTS OVER THE PAST SIX HOURS. MAXIMUM 
SUSTAINED SURFACE WINDS WERE ESTIMATED AT 115 KNOTS GUSTING TO 140 
KNOTS. SEE REF B (WTPN32 PGTW 280900) FOR FURTHER DETAILS.
      (3) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 93W) PREVIOUSLY LOCATED NEAR 
16.4N 143.5E IS NOW LOCATED NEAR 18.0N 143.9E, APPROXIMATELY 316 NM 
NORTH OF GUAM. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY AND A 
270805Z SSMIS 91 GHZ IMAGE DEPICT A BROAD AREA OF SHARP TROUGHING WITH 
PERSISTENT, DEEP CONVECTIVE BANDING HIDING THE PROSPECTIVE LOW LEVEL 
CIRCULATON CENTER (LLCC). A 271130Z ASCAT-C PARTIAL PASS SHOWS 15-20KT 
WINDS TO THE EAST OF THE ASSESSED CENTER. ENVIRONMENTAL ANALYSIS 
REVEALS FAVORABLE CONDITIONS FOR DEVELOPMENT WITH WARM (29-30 C) SST 
AND ROBUST POLEWARD OUTFLOW ALOFT OFFSET BY MODERATE (15-20KTS) 
VERTICAL WIND SHEAR. 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, AIDING IN ITS DEEPENING AND 
DEVELOPMENT. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 18 TO 23 
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 HIGH. SEE REF C (WTPN21 PGTW 271500) FOR 
FURTHER DETAILS.
      (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: UPDATED PARA 1.A.(1) WITH 08W FINAL 
WARNING INFORMATION.//
