1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 23AUG23 0000Z, TROPICAL DEPRESSION 08W (EIGHT) WAS 
LOCATED NEAR 17.1N 151.3E, APPROXIMATELY 423 NM EAST-NORTHEAST OF 
ANDERSEN AFB, GUAM, AND HAD TRACKED SOUTHWARD AT 05 KNOTS OVER THE 
PAST SIX HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 25 
KNOTS GUSTING TO 35 KNOTS. SEE REF A (WTPN31 PGTW 230300) FOR FURTHER 
DETAILS.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 90W) PREVIOUSLY LOCATED NEAR 
18.0N 151.5E IS NOW THE SUBJECT OF A TROPICAL CYCLONE WARNING. SEE 
PARA. 1.A.(1) FOR FURTHER DETAILS.
      (2) THE AREA OF CONVECTION (INVEST 91W) PREVIOUSLY LOCATED NEAR 
19.0N 126.9E IS NOW LOCATED NEAR 19.1N 126.4E, APPROXIMATELY 442 NM 
SOUTH OF KADENA AB, OKINAWA, JAPAN. ANIMATED MULTISPECTRAL SATELLITE 
IMAGERY AND A 222146Z SSMIS 91GHZ PASS DEPICT A CONSOLIDATING LLCC 
WITH DEEP CONVECTION BUILDING OVER THE CENTER AND FORMATIVE BANDING IN 
THE SOUTHWEST QUADRANT. ENVIRONMENTAL ANALYSIS INDICATES GENERALLY 
FAVORABLE CONDITIONS FOR DEVELOPMENT WITH WARM (29-30C) SST, LOW 
VERTICAL WIND SHEAR (5-10 KTS), AND GOOD OUTFLOW ALOFT. GLOBAL MODELS 
SHOW A STEADY NORTHWARD TRACK WITH GRADUAL DEVELOPMENT OVER THE NEXT 
48 HOURS. 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 HIGH. SEE REF B (WTPN21 PGTW 230230) 
FOR FURTHER DETAILS.
      (3) 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 WARNING 
STATUS AND UPGRADED AREA IN PARA 1.B.(2) TO HIGH.//
