1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
A. TROPICAL CYCLONE SUMMARY:
(1) AT 160600Z3 TROPICAL DEPRESSION 31W (MORT) WAS
LOCATED AT 15.6N2 121.8E2 MOVING WEST-NORTHWESTWARD AT 07
KNOTS AND DISSIPATING RAPIDLY. MAXIMUM SUSTAINED WINDS
WERE ESTIMATED AT 25 KNOTS WITH GUSTS TO 35 KNOTS. SEE
REF A (TROPICAL STORM MORT (31W) WARNING NR 23 (WTPN31
PGTW 160300)) FOR THE FINAL WARNING ON THIS SYSTEM.
(2) NO OTHER SIGNIFICANT TROPICAL CYCLONES.
B. TROPICAL DISTURBANCE SUMMARY:
(1) NO SUSPECT AREAS.
2. WESTERN SOUTH PACIFIC AREA (180 WEST TO 135E):
A. TROPICAL CYCLONE SUMMARY: NONE.
B. TROPICAL DISTURBANCE SUMMARY:
(1) THE AREA OF CONVECTION MENTIONED PREVIOUSLY
NEAR 8.5S3 173.0E1 HAS MOVED WESTWARD TO NEAR 8.5S3
170.0E0. VISIBLE, INFRARED, AND SSM/I SATELLITE IMAGERY,
AND SYNOPTIC DATA INDICATE THAT THIS TROPICAL DISTURBANCE
HAS BECOME MUCH BETTER ORGANIZED DURING THE PAST 12
HOURS. TWO LARGE, CIRCULAR CONVECTIVE CLOUD MASSES WERE
NOTED ROTATING CYCLONICALLY ABOUT THE CENTRAL POINT
MENTIONED ABOVE AND LOW-LEVEL CLOUD LINES CAN BE SEEN
SPIRALLY INTO THE SYSTEM CENTER. AN UPPER-LEVEL
ANTICYCLONE MAY ALSO BE DEVELOPING ABOVE THIS SYSTEM
BASED ON GOOD CIRRUS OUTFLOW AND WATER VAPOR-DERIVED
WINDS INDICATING THE PRESENCE OF STRONG DIVERGENCE OVER
EACH CONVECTIVE CLOUD MASS. HOWEVER, UNTIL THE TWO
CONVECTIVE MASSES MERGE OR ONE DISSIPATES, LOW-LEVEL
INFLOW WILL BE DISRUPTED INTO THE SYSTEM CENTER AND THE
WIND FIELD WILL REMAIN BROAD AND WEAK. MAXIMUM SUSTAINED
WINDS ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL
PRESSURE IS ESTIMATED TO BE 1005 MB. THE POTENTIAL FOR
SIGNIFICANT TROPICAL CYCLONE DEVELOPMENT WITHIN THE NEXT
24 HOURS IS FAIR.
(2) NO OTHER SUSPECT AREAS.
3. JUSTIFICATION FOR RE-ISSUANCE: TO UPGRADE POOR SUSPECT
AREA TO A FAIR SUSPECT AREA IN PARAGRAPH 2.B.(1).
