1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 13OCT20 0000Z, TROPICAL STORM 18W (NANGKA) WAS LOCATED 
NEAR 18.8N 112.3E, APPROXIMATELY 236 NM SOUTH-SOUTHWEST OF HONG 
KONG, AND HAD TRACKED WEST-NORTHWESTWARD AT 09 KNOTS OVER THE PAST 
SIX HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 40 
KNOTS GUSTING TO 50 KNOTS. SEE REF A (WTPN33 PGTW 130300) FOR 
FURTHER DETAILS.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 94W) PREVIOUSLY LOCATED 
NEAR 9.2N 131.0E, IS NOW LOCATED NEAR 11.0N 127.9S, APPROXIMATELY 
458 NM NORTHWEST OF PALAU. ANIMATED ENHANCED INFRARED SATELLITE 
IMAGERY AND A 130122Z METOP-B 89GHZ IMAGE REVEAL A BROAD LOW LEVEL 
CIRCULATION WITH DISORGANIZED, BUT CONSOLIDATING 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 AGREEMENT THAT INVEST 94W WILL CONTINUE TO TRACK GENERALLY 
WESTWARD AND MAKE LANDFALL IN THE CENTRAL PHILIPPINES BEFORE 
CONSOLIDATING FURTHER IN THE SOUTH CHINA SEA. MAXIMUM SUSTAINED 
SURFACE WINDS ARE ESTIMATED AT 15 TO 20 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 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.//
