1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 20OCT23 1800Z, TROPICAL DEPRESSION 16W (SANBA) WAS LOCATED 
NEAR 19.9N 108.7E, APPROXIMATELY 235 NM NORTH OF DA NANG, VIETNAM, AND 
HAD TRACKED SOUTHWESTWARD AT 07 KNOTS OVER THE PAST SIX HOURS. MAXIMUM 
SUSTAINED SURFACE WINDS WERE ESTIMATED AT 25 KNOTS GUSTING TO 35 KNOTS. 
SEE REF A (WTPN31 PGTW 202100) FOR THE FINAL WARNING ON THIS SYSTEM.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY: NONE.
   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:
      (1) THE AREA OF CONVECTION (INVEST 90P) PREVIOUSLY LOCATED NEAR 
4.8S 169.9E IS NOW LOCATED NEAR 7.1S 169.3E, APPROXIMATELY 571 NM EAST-
NORTHEAST OF HONIARA, SOLOMON ISLANDS. ANIMATED MULTISPECTRAL SATELLITE 
IMAGERY AND A 201833Z SSMIS 91 GHZ MICROWAVE IMAGE DEPICT A 
CONSOLIDATING, PARTIALLY EXPOSED LOW-LEVEL CIRCULATION CENTER (LLCC) 
WITH FLARING CONVECTION AND DEEP FORMATIVE BANDING ENVELOPING THE 
SYSTEM. ENVIRONMENTAL ANALYSIS INDICATES THAT 90P IS IN A FAVORABLE 
ENVIRONMENT FOR DEVELOPMENT WITH ROBUST POLEWARD OUTFLOW ALOFT, LOW (10-
15 KTS) VERTICAL WIND SHEAR, AND WARM (29-30 C) SST. GLOBAL MODELS ARE 
IN GOOD AGREEMENT THAT 90P WILL TRACK SOUTHWARD AND CONTINUE TO DEVELOP 
OVER THE NEXT 48 HOURS. MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 
20 TO 25 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 MEDIUM.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
3. JUSTIFICATION FOR REISSUE: UPDATED PARA 1.A.(1) WITH 16W FINAL 
WARNING INFORMATION AND UPGRADED AREA IN PARA 2.B.(1) TO MEDIUM.//
