1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
   A. TROPICAL CYCLONE SUMMARY:
      (1) AT 200000Z2 TROPICAL STORM ROSIE (10W) WAS
LOCATED AT 13.6N0 137.9E0, MOVING NORTHWESTWARD AT 06
KNOTS.  MAXIMUM SUSTAINED WINDS WERE ESTIMATED AT 35
KNOTS WITH GUSTS TO 45 KNOTS. SEE REF A (TROPICAL STORM
ROSIE (10W) WARNING NR 6 (WTPN31 PGTW 200300)) AND SIX-
HOURLY UPDATES FOR FURTHER DETAILS.
      (2) NO OTHER TROPICAL CYCLONES.
   B. TROPICAL DISTURBANCE SUMMARY:
      (1) THE LOW-LEVEL CIRCULATION CENTER PREVIOUSLY
LOCATED NEAR 28N0 175E3 IS NOW LOCATED NEAR 24N6 172E0.
THE LOW LEVEL CIRCULATION CENTER HAS BECOME LESS WELL
DEFINED OVER THE PAST 24 HOURS.  CONVECTION REMAINS
SPORADIC. 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.
      (2) AN AREA OF CONVECTION IS LOCATED NEAR 23N5
152E8.  ANIMATED VISIBLE SATELLITE IMAGERY AND SYNOPTIC
DATA INDICATE A TIGHT CIRCULATION CENTER WITH SCATTERED
CONVECTION. 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 27N9
130E4. ANIMATED VISIBLE SATELLITE IMAGERY SHOWS MODERATE
CONVECTION AROUND A TIGHT LOW LEVEL CIRCULATION CENTER.
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.
      (4) NO OTHER SUSPECT AREAS.
