1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 19OCT23 1800Z, TROPICAL STORM 16W (SANBA) WAS LOCATED 
NEAR 21.4N 109.3E, APPROXIMATELY 192 NM EAST OF HANOI, VIETNAM, AND 
HAD TRACKED NORTH-NORTHEASTWARD AT 07 KNOTS OVER THE PAST SIX HOURS. 
MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 40 KNOTS GUSTING TO 
50 KNOTS. SEE REF A (WTPN31 PGTW 192100) FOR FURTHER DETAILS.
      (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) AN AREA OF CONVECTION (INVEST 90P) HAS PERSISTED NEAR 4.3S 
170.2E, APPROXIMATELY 700 NM NORTHEAST OF HONIARA, SOLOMON ISLANDS. 
ANIMATED MULTISPECTRAL SATELLITE IMAGERY AND A 191730Z SSMIS 91GHZ 
MICROWAVE PARTIAL PASS DEPICT PERSISTENT DEEP CONVECTION IN THE 
SOUTHWESTERN QUADRANT OF A GRADUALLY CONSOLIDATING LOW LEVEL 
CIRCULATION CENTER (LLCC). A 191825Z SMOS PASS REVEALS WINDS LIMITED 
TO 15-25 KNOTS AROUND THE LLCC. ENVIRONMENTAL ANALYSIS REVEALS 
FAVORABLE CONDITIONS FOR INTENSIFICATION WITH LOW TO MODERATE (15-
20KT) VWS, WARM (30-31C) SST, AND AN UPPER LEVEL POINT SOURCE TO THE 
NORTH PROVIDING GOOD OUTFLOW. GLOBAL MODELS ARE IN AGREEMENT THAT 90P 
WILL CONTINUE TO GRADUALLY DEVELOP AS IT TRACKS
SOUTHWESTWARD TOWARD THE SOLOMON ISLANDS. MAXIMUM SUSTAINED SURFACE 
WINDS ARE ESTIMATED AT 18 TO 23 KNOTS. MINIMUM SEA LEVEL PRESSURE IS 
ESTIMATED TO BE NEAR 1006 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A 
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS LOW.
      (2) NO OTHER SUSPECT AREAS.
   C. SUBTROPICAL SYSTEM SUMMARY: NONE.
3. JUSTIFICATION FOR REISSUE: ADDED LOW AREA IN PARA. 2.B.(1).//
