1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 260000Z8 TYPHOON ORSON (19W) WAS LOCATED AT
25.4N1 149.7E1, MOVING EAST-NORTHEASTWARD AT 07 KNOTS.
MAXIMUM SUSTAINED WINDS WERE ESTIMATED AT 115 KNOTS WITH
GUSTS TO 140 KNOTS. SEE REF A (TROPICAL CYCLONE 19W
WARNING NR 18 (WTPN32 PGTW 260300)) AND SIX-HOURLY
UPDATES FOR FURTHER DETAILS.
      (2) AT 260000Z8 TROPICAL STORM PIPER (20W) WAS
LOCATED AT 40.4N8 158.6E0, MOVING NORTHWARD AT 24 KNOTS.
MAXIMUM SUSTAINED WINDS WERE ESTIMATED AT 60 KNOTS WITH
GUSTS TO 75 KNOTS. SEE REF B (TROPICAL CYCLONE 20W
WARNING NR 13 (WTPN33 PGTW 260300)) AND SIX-HOURLY
UPDATES FOR FURTHER DETAILS.
(3) AT 260000Z8 TROPICAL DEPRESSION 21W WAS LOCATED
AT 31.4N8 161.9E7, MOVING NORTHWARD AT 05 KNOTS. MAXIMUM
SUSTAINED WINDS WERE ESTIMATED AT 25 KNOTS WITH GUSTS TO
35 KNOTS. SEE REF C (TROPICAL DEPRESSION 21W WARNING NR
01 (WTPN31 PGTW 260300)) AND TWELVE-HOURLY UPDATES FOR
FURTHER DETAILS.
(4) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
(1) THE PERSISTENT LOW-LEVEL CIRCULATION CENTER
PREVIOUSLY LOCATED NEAR 18N9 131E5 REMAINS NEAR 18N9
131E5. SATELLITE IMAGERY AND SYNOPTIC DATA INDICATE THE
PRESENCE OF A LOW-LEVEL CYCLONIC CIRCULATION
EMBEDDED WITHIN  THE MONSOON TROUGH. CONVECTION
ASSOCIATED WITH THE DISTURBANCE IS MINIMAL MAXIMUM
SUSTAINED WINDS ARE ESTIMATED AT 15 TO 20 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) THE AREA OF CONVECTION PREVIOUSLY LOCATED
NEAR 21N3 116E8 HAS DISSIPATED AND IS NO LONGER
CONSIDERED SUSPECT.
(3) THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR
21N3 180E9 IS NOW LOCATED NEAR 24N6 177E5. VISIBLE
SATELLITE IMAGERY AND SYNOPTIC SHIP REPORTS INDICATE THE
PRESENCE OF A LOW-LEVEL CYCLONIC CIRCULATION. THE
CONVECTION ASSOCIATED WITH THIS DISTURBANCE IS MOSTLY
UNORGANIZED, WITH THE DEEPEST CONVECTION LOCATED TO THE
EAST OF THE LOW-LEVEL CIRCULATION. MAXIMUM SUSTAINED
WINDS ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL
PRESSURE IS ESTIMATED TO BE 1008 MB.  THE SYSTEM HAS
MOVED EASTWARD OVER THE PAST 24 HOURS AND IS NO LONGER
CONSIDERED SUSPECT FOR DEVELOPMENT WITHIN THE JOINT
TYPHOON WARNING CENTER AREA OF RESPONSIBILITY (WEST OF
180 LONGITUDE).
(4) NO OTHER SUSPECT AREAS.
2.  WESTERN SOUTH PACIFIC AREA (180 WEST TO 135E):
   A. TROPICAL CYCLONE SUMMARY: NONE.
   B. TROPICAL DISTURBANCE SUMMARY NONE.
