1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
A. TROPICAL CYCLONE SUMMARY:
(1) AT 280000Z0 TYPHOON YATES (28W) WAS LOCATED AT
21.1N4 138.6E8, MOVING NORTHWESTWARD AT 06 KNOTS. MAXIMUM
SUSTAINED WINDS WERE ESTIMATED AT 125 KNOTS WITH GUSTS TO
150 KNOTS. SEE REF A (TYPHOON YATES (28W) WARNING NR 22
(WTPN31 PGTW 280300)) AND SIX-HOURLY UPDATES FOR FURTHER
DETAILS.
(2) AT 280000Z0 TYPHOON ZANE (29W) WAS LOCATED AT
22.8N2 125.4E2, MOVING NORTHWARD AT 05 KNOTS. MAXIMUM
SUSTAINED WINDS WERE ESTIMATED AT 110 KNOTS WITH GUSTS TO
135 KNOTS. SEE REF B (TYPHOON ZANE (29W) WARNING NR 17
(WTPN32 PGTW 280300)) 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 110E9 HAS DISSIPATED AND IS NO LONGER
CONSIDERED SUSPECT.
(2) AN AREA OF CONVECTION IS LOCATED NEAR 20N2
149E4. SATELLITE IMAGERY AND SYNOPTIC DATA INDICATE THIS
CONVECTION IS ASSOCIATED WITH BOTH THE MONSOON TROUGH AND
CONVERGENCE INTO TYPHOON YATES (28W) AND WITH A TROPICAL
UPPER TROPOSPHERIC TROUGH (TUTT) CELL EAST OF TY YATES.
ANIMATED IMAGERY INDICATES A LARGE MESOSCALE CONVECTIVE
CLUSTER INITIATED BY THE SYNOPTIC SITUATION HAS RECENTLY
COLLAPSED, LEAVING AN ANNULUS OF CONNECTED THUNDERSTORMS
ALONG THE OUTFLOW BOUNDARY. THE FAVORABLE SYNOPTIC
SITUATION STILL EXISTS AND COULD LEAD TO RECONSOLIDATION
OF THIS CONVECTION. MAXIMUM SUSTAINED WINDS ARE ESTIMATED
AT 15 TO 20 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.
(3) NO OTHER SUSPECT AREAS.
2.  WESTERN SOUTH PACIFIC AREA (180 WEST TO 135E):
A. TROPICAL CYCLONE SUMMARY: NONE.
B. TROPICAL DISTURBANCE SUMMARY: NONE.
