1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 11OCT20 0000Z, TROPICAL STORM 16W (CHAN-HOM) WAS 
LOCATED NEAR 32.2N 140.5E, APPROXIMATELY 190 NM SOUTH-SOUTHEAST OF 
YOKOSUKA, JAPAN, AND HAD TRACKED EASTWARD AT 09 KNOTS OVER THE PAST 
SIX HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 40 
KNOTS GUSTING TO 50 KNOTS. SEE REF A (WTPN31 PGTW 110300) FOR 
FURTHER DETAILS.
      (2) AT 11OCT20 0000Z, TROPICAL STORM 17W (LINFA) WAS LOCATED 
NEAR 14.8N 109.5E, APPROXIMATELY 100 NM SOUTHEAST OF DA NANG, 
VIETNAM, AND HAD TRACKED WESTWARD AT 08 KNOTS OVER THE PAST SIX 
HOURS. MAXIMUM SUSTAINED SURFACE WINDS WERE ESTIMATED AT 40 KNOTS 
GUSTING TO 50 KNOTS. SEE REF B (WTPN32 PGTW 110300) FOR FURTHER 
DETAILS.
      (3) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) AN AREA OF CONVECTION (INVEST 93W) HAS PERSISTED NEAR 
16.9N 119.2E, APPROXIMATELY 166 NM NORTH-NORTHWEST OF MANILLA, 
PHILIPPINES. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY AND AN 
110202Z METOP-B 89GHZ MICROWAVE IMAGE REVEAL SHALLOW FRAGMENTED 
FORMATIVE BANDING WRAPPING INTO A LOW LEVEL CIRCULATION WITH LIMITED 
DEEP CONVECTION. AN 110204Z ASCAT-B PASS REVEALS MAINLY 10-15KT 
WINDS WITH SOME 20KT WINDS DISPLACED TO THE NORTH. INVEST 93W IS IN 
A FAVORABLE ENVIRONMENT FOR DEVELOPMENT WITH LOW (<15KTS) VERTICAL 
WIND SHEAR, MODERATE UPPER LEVEL DIFFLUENCE, AND WARM (29-30C) SEA 
SURFACE TEMPERATURES. GLOBAL MODELS ARE IN GOOD AGREEMENT THAT 
INVEST 93W WILL CONTINUE TO CONSOLIDATE AND TRACK WEST-NORTHWESTWARD 
ACROSS THE SOUTH CHINA SEA. MAXIMUM SUSTAINED SURFACE WINDS ARE 
ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED 
TO BE NEAR 1002 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A 
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS MEDIUM.
      (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.//
