1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 14OCT20 0000Z, TROPICAL STORM 18W (NANGKA) WAS LOCATED 
NEAR 20.0N 106.8E, APPROXIMATELY 78 NM SOUTHEAST OF HANOI, VIETNAM, AND 
HAD TRACKED WESTWARD AT 20 KNOTS OVER THE PAST SIX HOURS. MAXIMUM 
SUSTAINED SURFACE WINDS WERE ESTIMATED AT 45 KNOTS GUSTING TO 55 KNOTS. 
SEE REF A (WTPN33 PGTW 140300) FOR FURTHER DETAILS.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION (INVEST 94W) PREVIOUSLY LOCATED 
NEAR 11.0N 127.9E, IS NOW LOCATED NEAR 12.6N 124.0E, APPROXIMATELY 
213 NM SOUTHEAST OF MANILA, PHILIPPINES. ANIMATED ENHANCED INFRARED 
SATELLITE IMAGERY AND A 140101Z METOP-B 89GHZ IMAGE REVEAL A 
CONSOLIDATING LOW LEVEL CIRCULATION WITH FLARING CONVECTION. INVEST 94W 
IS IN A FAVORABLE ENVIRONMENT FOR DEVELOPMENT WITH LOW (<15 KTS) 
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 OVER 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.
