1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
       (1) AT 260000Z8 TYPHOON YATES (28W) WAS LOCATED AT
16.5N2 144.0E9, MOVING WEST-NORTHWESTWARD AT 08 KNOTS.
MAXIMUM SUSTAINED WINDS WERE ESTIMATED AT 120 KNOTS WITH
GUSTS TO 145 KNOTS. SEE REF A (TYPHOON YATES (28W)
WARNING NR 14 (WTPN31 PGTW 260300)) AND SIX-HOURLY
UPDATES FOR FURTHER DETAILS.
       (2) AT 260000Z8 TYPHOON ZANE (29W) WAS LOCATED AT
19.0N0 129.5E7, MOVING NORTHWESTWARD AT 12 KNOTS. MAXIMUM
SUSTAINED WINDS WERE ESTIMATED AT 75 KNOTS WITH GUSTS TO
90 KNOTS. SEE REF B (TYPHOON ZANE (29W) WARNING NR 09
(WTPN32 PGTW 260300)) AND SIX-HOURLY UPDATES FOR FURTHER
DETAILS.
   (3) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE AREA OF CONVECTION PREVIOUSLY MENTIONED
NEAR 10N1 167E4 HAS WEAKENED AND BEEN ABSORBED INTO THE
MONSOON TROUGH AND IS NO LONGER CONSIDERED SUSPECT.
      (2) AN AREA OF MODERATE CONVECTION HAS MOVED ACROSS
THE DATELINE AND WAS LOCATED NEAR 9.0N9 179.9E6. THIS
ACTIVITY IS ASSOCIATED WITH A WEAK LOW-LEVEL CYCLONIC
CIRCULATION THAT IS LOCATED BENEATH STRONG UPPER-LEVEL
DIFLUENCE. 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 POOR DUE TO A
LACK OF PERSISTENT, ORGANIZED DEEP CONVECTION.
      (3) THE BAND OF STRONG CONVECTION ASSOCIATED WITH
AN ACTIVE MONSOON TROUGH EXTENDS FROM 9.5N4 128.5E6
EASTWARD TO 13.0N4 133.5E2 TO 14.5N0 147.0E2 TO 16.0N7
157.03. THE MOST LIKELY REGIONS FOR ANY DEVELOPMENT WOULD
BE ASSOCIATED WITH WEAK LOW PRESSURE WAVES LOCATED NEAR
13.0N4 133.5E2 AND 14.5N0 147.0E2. MAXIMUM SUSTAINED
WINDS ARE ESTIMATED AT 15 TO 20 KNOTS WITH GUSTS TO 30-35
KNOTS. MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE 1007
MB. THE POTENTIAL FOR SIGNIFICANT TROPICAL CYCLONE
DEVELOPMENT WITHIN THE NEXT 24 HOURS IS POOR DUE TO CLOSE
INTERACTION WITH TYPHOON YATES (28W) AND TYPHOON ZANE
(29W).
      (4) NO OTHER SUSPECT AREAS.
2.  WESTERN SOUTH PACIFIC AREA (180 WEST TO 135E):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY: NONE.
