1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
A. TROPICAL CYCLONE SUMMARY:
(1) AT 250000Z7 TYPHOON ORSON (19W) WAS LOCATED AT
24.3N9 146.6E7, MOVING EASTWARD AT 10 KNOTS. MAXIMUM
SUSTAINED WINDS WERE ESTIMATED AT 100 KNOTS WITH GUSTS TO
125 KNOTS. SEE REF A (TROPICAL CYCLONE 19W WARNING NR 14
(WTPN32 PGTW 250300)) AND SIX-HOURLY UPDATES FOR FURTHER
DETAILS.
(2) AT 250000Z7 TROPICAL STORM PIPER (20W) WAS
LOCATED AT 29.0N1 160.2E9, MOVING NORTHWARD AT 08 KNOTS.
MAXIMUM SUSTAINED WINDS WERE ESTIMATED AT 45 KNOTS WITH
GUSTS TO 55 KNOTS. SEE REF B (TROPICAL CYCLONE 20W
WARNING NR 09 (WTPN33 PGTW 250300)) AND SIX-HOURLY
UPDATES FOR FURTHER DETAILS.
(3) NO OTHER TROPICAL CYCLONES.
B. TROPICAL DISTURBANCE SUMMARY:
(1) THE LOW-LEVEL CIRCULATION CENTER PREVIOUSLY
LOCATED NEAR 17N8 132E6 IS NOW LOCATED NEAR 18N9 131E5.
SATELLITE IMAGERY AND SYNOPTIC DATA INDICATE THE PRESENCE
OF A WEAK LOW-LEVEL CYCLONIC CIRCULATION EMBEDDED WITHIN
THE MONSOON TROUGH. CONVECTION HAS INCREASED OVER THE
PAST 24 HOURS, BUT REMAINS MINIMAL. THIS DISTURBANCE HAS
PERSISTED FOR OVER 96 HOURS. MAXIMUM SUSTAINED WINDS ARE
ESTIMATED AT 10 TO 15 KNOTS. MINIMUM SEA LEVEL PRESSURE
IS  ESTIMATED TO BE 1008MB. THE POTENTIAL FOR SIGNIFICANT
TROPICAL CYCLONE DEVELOPMENT WITHIN THE NEXT 24 HOURS IS
POOR.
(2) AN AREA OF CONVECTION IS LOCATED NEAR 21N3
116E8.  VISIBLE SATELLITE IMAGERY AND SYNOPTIC DATA
INDICATE THE PRESENCE OF A LOW-LEVEL CYCLONIC
CIRCULATION. THIS DISTURBANCE IS LOCATED TO THE SOUTHEAST
OF A TROPICAL UPPER TROPOSPHERIC TROUGH (TUTT) CELL. THE
DIFFLUENT FLOW ALOFT IS ENHANCING CONVECTIVE ACTIVITY.
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.
(3) AN AREA OF CONVECTION IS LOCATED NEAR 21N3
180E9. VISIBLE SATELLITE IMAGERY INDICATES THE PRESENCE
OF A LOW-LEVEL CYCLONIC CIRCULATION. THE CONVECTION
ASSOCIATED WITH THIS DISTURBANCE IS MOSTLY UNORGANIZED.
MAXIMUM SUSTAINED WINDS ARE ESTIMATED AT 15 TO 20 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.
(4) NO OTHER SUSPECT AREAS.
2.  WESTERN SOUTH PACIFIC AREA (180 WEST TO 135E):
A. TROPICAL CYCLONE SUMMARY: NONE.
B. TROPICAL DISTURBANCE SUMMARY NONE.
