1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 09OCT20 0000Z, TYPHOON 16W (CHAN-HOM) WAS LOCATED NEAR 
30.1N 133.2E, APPROXIMATELY 453 NM SOUTHWEST OF YOKOSUKA, JAPAN, AND 
HAD TRACKED NORTHWARD AT 03 KNOTS OVER THE PAST SIX HOURS. MAXIMUM 
SUSTAINED SURFACE WINDS WERE ESTIMATED AT 75 KNOTS GUSTING TO 90 
KNOTS. SEE REF A (WTPN31 PGTW 090300) FOR FURTHER DETAILS.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY: 
      (1)AN AREA OF CONVECTION (INVEST 92W) HAS PERSISTED NEAR 13.2N 
116.5E, APPROXIMATELY 270 NM WEST-SOUTHWEST OF MANILA, PHILIPPINES. 
ANIMATED ENHANCED INFRARED SATELLITE IMAGERY AND A 090000Z GMI 89GHZ 
IMAGE DEPICT FLARING CONVECTION WITH LOW LEVEL BANDING WRAPPING INTO 
A LOW LEVEL CIRCULATION CENTER. INVEST 92W IS IN AN ENVIRONMENT THAT 
IS MODERATELY FAVORABLE FOR FURTHER DEVELOPMENT WITH EQUATORWARD 
OUTFLOW, MODERATE (15-25 KTS) VERTICAL WIND SHEAR (VWS), AND VERY 
WARM (31-32C) SEA SURFACE TEMPERATURES (SST). GLOBAL MODELS ARE 
IN GOOD AGREEMENT THAT 92W WILL CONTINUE TO TRACK GENERALLY WESTWARD 
AS IT STRENGTHENS AND CONSOLIDATES. MAXIMUM SUSTAINED SURFACE WINDS 
ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL PRESSURE IS 
ESTIMATED TO BE NEAR 1009 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A 
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS UPGRADED TO 
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.
