1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
A. TROPICAL CYCLONE SUMMARY:
(1) AT 110000Z2 TROPICAL DEPRESSION 31W WAS
LOCATED AT 11.8N0 138.9E1, MOVING WEST-NORTHWESTWARD AT
08 KNOTS. MAXIMUM SUSTAINED WINDS WERE ESTIMATED AT 30
KNOTS WITH GUSTS TO 40 KNOTS. SEE REF A (TROPICAL
DEPRESSION 31W WARNING NR 02 (WTPN31 PGTW  110300) AND
SIX-HOURLY UPDATES FOR FURTHER DETAILS.
(2) NO OTHER SIGNIFICANT TROPICAL CYCLONES.
B. TROPICAL DISTURBANCE SUMMARY:
(1) AT 091900Z9, THE AREA OF CONVECTION PREVIOUSLY
MENTIONED NEAR 11.1N3 141.1E7 AND WAS THE SUBJECT OF A
TROPICAL CYCLONE FORMATION ALERT HAS DEVELOPED
(2)  THE AREA OF CONVECTION MENTIONED PREVIOUSLY
NEAR 10N1 175E3 IS NOW LOCATED NEAR 12.6N9 171.5E4.
HOWEVER, DURING THE PAST 06 HOURS, THIS DISTURBANCE HAS
REMAINED NEARLY STATIONARY. VISIBLE SATELLITE IMAGERY AND
110000Z2 SYNOPTIC DATA INDICATE A WELL-DEFINED LOW-LEVEL
CYCLONIC CIRCULATION BENEATH THE SOUTHEAST QUADRANT OF AN
UPPER-LEVEL ANTICYCLONE THAT IS LOCATED NEAR 14N5 168E5.
THERE IS LITTLE CONVECTION ASSOCIATED WITH THIS SYSTEM.
HOWEVER, NEW MODERATE CONVECTION HAS DEVELOPED OVER THE
SYSTEM CENTER DURING THE PAST 03 HOURS. ALTHOUGH NEARBY
SURFACE PRESSURES ARE HIGHER THAN NORMAL, THIS SYSTEM
REMAINS A TIGHTLY ORGANIZED TROPICAL DISTURBANCE. 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 FAIR.
(3) AN AREA OF CONVECTION HAS PERSISTED FOR 24
HOURS NEAR 06N6 104E5. SYNOPTIC DATA INDICATES A WEAK,
LOW-LEVEL CYCLONIC CIRCULATION BENEATH MODERATE, UPPER-
LEVEL ANTICYCLONIC FLOW. LAND INTERACTION WITH THE
SOUTHERN MALAY PENINSULA SHOULD INHIBIT DEVELOPMENT.
MAXIMUM SUSTAINED WINDS ARE  ESTIMATED AT 10 TO 15 KNOTS.
MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE 1009 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.
