SUBJ/SIGNIFICANT TROPICAL WEATHER ADVISORY FOR THE
WESTERN PACIFIC OCEAN/170600Z/180600Z NOV 97//
RMKS/
1. WESTERN NORTH PACIFIC AREA (180 TO MALAY PENINSULA):
A. TROPICAL CYCLONE SUMMARY: NONE.
B. TROPICAL DISTURBANCE SUMMARY:
(1) AN AREA OF CONVECTION HAS PERSISTED FOR MORE
THAN 24 HOURS NEAR 21N3 168E5. SATELLITE IMAGERY AND
SYNOPTIC DATA INDICATE THE PRESENCE OF A SMALL LOW-LEVEL
CYCLONIC CIRCULATION BENEATH DIVERGENT UPPER-LEVEL FLOW.
THIS SYSTEM IS ASSOCIATED WITH A LOW PRESSURE AREA
EMBEDDED IN THE TROPICAL UPPER-TROPOSPHERIC TROUGH TUTT)
AND MOST OF THE DEEP CONVECTION IS DISPLACED TO THE
NORTHEAST OF THE SURFACE CIRCULATION. MAXIMUM SUSTAINED
WINDS ARE ESTIMATED AT 15 TO 20 KNOTS WITH HIGHER GUSTS
TO THE NORTHEAST. MINIMUM SEA-LEVEL PRESSURE IS ESTIMATED
TO BE 1010 MB. THE POTENTIAL FOR SIGNIFICANT TROPICAL
CYCLONE DEVELOPMENT WITHIN THE NEXT 24 HOURS IS POOR.
(2) NO OTHER 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 170.0E0 HAS MOVED WESTWARD TO NEAR 8.5S3
168.0E5. VISIBLE AND INFRARED SATELLITE IMAGERY, AND
SYNOPTIC DATA INDICATE THIS TROPICAL DISTURBANCE HAS
CONTINUED TO BECOME BETTER ORGANIZED DESPITE A DECREASE
IN THE CENTRAL CONVECTION DURING THE PAST 06 HOURS. WATER
VAPOR-DERIVED WINDS INDICATE THE PRESENCE OF A WEAK
ANTICYCLONE ABOVE THE LOW-LEVEL CIRCULATION CENTER.
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.
