SUBJ/SIGNIFICANT TROPICAL WEATHER ADVISORY FOR THE
WESTERN PACIFIC OCEAN/151830Z/160600Z JUL 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 IS LOCATED NEAR 16N7
116E8. THE CONVECTION HAS BECOME BETTER ORGANIZED OVER
THE PAST TWELVE HOURS. ANIMATED INFRARED SATELLITE
IMAGERY SUGGESTS THE PRESENCE OF A POSSIBLE LOW-LEVEL
CIRCULATION CENTER LOCATED WEST OF LUZON IN THE SOUTH
CHINA SEA. ANIMATED WATER VAPOR IMAGERY AND WATER VAPOR
DERIVED WINDS INDICATE A REGION OF DIVERGENT OUTFLOW OVER
THE AREA. 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) THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR
7N7 166E3 IS NOW LOCATED NEAR 4N4 161E8. ANIMATED
INFRARED SATELLITE IMAGERY AND SYNOPTIC DATA INDICATE THE
PRESENCE OF A WEAK LOW-LEVEL CIRCULATION CENTER. ANIMATED
WATER VAPOR IMAGERY AND WATER VAPOR DERIVED WINDS
INDICATE DIVERGENT OUTFLOW OVER THE AREA. 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) THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR
9N9 143E8 IS NOW LOCATED NEAR 8N8 142E7. ANIMATED
INFRARED SATELLITE IMAGERY AND SYNOPTIC DATA INDICATE THE
PRESENCE OF A BROAD LOW-LEVEL CIRCULATION CENTER LOCATED
BENEATH DIVERGENT OUTFLOW ALOFT. MAXIMUM SUSTAINED WINDS
ARE ESTIMATED AT 10 TO 15 KNOTS. MINIMUM SEA LEVEL
PRESSURE IS ESTIMATED TO BE 1007 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.
