1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
(1) AT 200600Z8 TROPICAL STORM TOM (25W) WAS
LOCATED AT 34.0N7 161.3E1, MOVING EASTWARD AT 16 KNOTS.
MAXIMUM SUSTAINED WINDS WERE ESTIMATED AT 45 KNOTS WITH
GUSTS TO 55 KNOTS. SEE REF A (TROPICAL STORM TOM (25W)
WARNING NR 035 (WTPN31 PGTW 200900)) FOR FINAL WARNING.
  (2) AT 201200Z5 TYPHOON VIOLET (26W) WAS LOCATED AT
26.0N8 132.6E2, MOVING NORTH-NORTHEASTWARD AT 06 KNOTS.
MAXIMUM SUSTAINED WINDS WERE ESTIMATED AT 85 KNOTS WITH
GUSTS TO 105 KNOTS. SEE REF B (TYPHOON VIOLET (26W)
WARNING NR 034 (WTPN33 PGTW 201500)) AND SIX-HOURLY
UPDATES FOR FURTHER DETAILS.
(3) AT 201200Z5 TROPICAL STORM WILLIE (27W) WAS
LOCATED AT 20.1N3 109.6E6, MOVING WESTWARD AT 05 KNOTS.
MAXIMUM SUSTAINED WINDS WERE ESTIMATED AT 60 KNOTS WITH
GUSTS TO 75 KNOTS. SEE REF C (TROPICAL STORM WILLIE (27W)
WARNING NR 012 (WTPN32 PGTW 201500)) AND SIX-HOURLY
UPDATES FOR FURTHER DETAILS.
(4) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
(1) THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR
9N9 170E8 IS NOW LOCATED NEAR 9.5N4 168.5E0. ANIMATED
VISIBLE SATELLITE IMAGERY AND SYNOPTIC DATA INDICATE A
LOW-LEVEL CIRCULATION REMAINS ASSOCIATED WITH THIS
CONVECTION. THE CONVECTIVE ORGANIZATION ASSOCIATED WITH
THIS CIRCULATION HAS REMAINED PERSISTENT OVER THE PAST 24
HOURS. MAXIMUM SUSTAINED WINDS ARE ESTIMATED AT 10 TO 15
KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE 1008
MB. THE POTENTIAL FOR SIGNIFICANT TROPICAL CYCLONE
DEVELOPMENT WITHIN THE NEXT 24 HOURS IS FAIR.
(2) AN AREA OF CONVECTION IS LOCATED NEAR 5N5
152E8.  SATELLITE IMAGERY AND SYNOPTIC DATA INDICATE THE
PRESENCE OF A BROAD LOW-LEVEL CIRCULATION WITH
INTERMITTENT CONVECTION. MAXIMUM SUSTAINED WINDS ARE
ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL PRESSURE
IS ESTIMATED TO BE 1008 MB. WATER VAPOR DERIVED WINDS
INDICATE MODERATE UPPER-LEVEL EASTERLY WINDS ARE
INHIBITING DEVELOPMENT AT THIS TIME.  THE POTENTIAL FOR
SIGNIFICANT TROPICAL CYCLONE DEVELOPMENT WITHIN THE NEXT
24 HOURS IS POOR.
(3) NO OTHER SUSPECT AREAS.
2.  WESTERN SOUTH PACIFIC AREA (180 WEST TO 135E):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY: NONE.
