1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 12OCT20 0600Z, TROPICAL DEPRESSION 16W (CHAN-HOM) WAS 
LOCATED NEAR 29.4N 142.4E, APPROXIMATELY 138 NM NORTH OF CHICHI 
JIMA, AND HAD TRACKED SOUTHWARD AT 08 KNOTS OVER THE PAST SIX HOURS. 
MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 25 KNOTS GUSTING 
TO 35 KNOTS. SEE REF A (WTPN31 PGTW 120900) FOR THE FINAL WARNING ON 
THIS SYSTEM.
      (2) AT 12OCT20 0600Z, TROPICAL STORM 18W (NANGKA) WAS LOCATED 
NEAR 17.9N 115.7E, APPROXIMATELY 277 NM SOUTH-SOUTHEAST OF HONG 
KONG, AND HAD TRACKED WESTWARD AT 13 KNOTS OVER THE PAST SIX HOURS. 
MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 35 KNOTS GUSTING 
TO 45 KNOTS. SEE REF B (WTPN33 PGTW 120900) FOR FURTHER DETAILS.
      (3) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 94W) HAS PERSISTED NEAR 
9.2N 131.0E, APPROXIMATELY 300 NM NORTHWEST OF PALAU. ANIMATED 
ENHANCED INFRARED SATELLITE IMAGERY AND A 120449Z AMSR2 89GHZ IMAGE 
REVEAL A BROAD LOW LEVEL CIRCULATION WITH DISORGANIZED FLARING 
CONVECTION. INVEST 94W IS IN A FAVORABLE ENVIRONMENT FOR DEVELOPMENT 
WITH LOW (<15KTS) VERTICAL WIND SHEAR, GOOD EQUATORWARD AND POLEWARD 
OUTFLOW, AND WARM (29-30C) SEA SURFACE TEMPERATURES. GLOBAL MODELS 
ARE IN SOME AGREEMENT THAT INVEST 94W WILL CONTINUE TO TRACK 
NORTHWESTWARD AND MAKE LANDFALL IN THE CENTRAL PHILIPPINES BEFORE 
CONSOLIDATING FURTHER IN THE SOUTH CHINA SEA. MAXIMUM SUSTAINED 
SURFACE WINDS ARE ESTIMATED AT 10 TO 15 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 REMAINS LOW.
      (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: ISSUED FINAL WARNING FOR TD 16W.//
