THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 6.0N }
147.1E, IS NOW LOCATED NEAR 7.5N 143.7E, APPROXIMATELY 350 NM SOUTH
OF GUAM. ANIMATED MULTISPECTRAL SATELLITE IMAGERY (MSI) SHOWS A MID-
LEVEL CIRCULATION LOCATED OVER AN INVERTED TROUGH THAT IS ORIENTED
NORTHEAST TO SOUTHWEST, EXTENDING FROM 7N 143E TO 1N 135E. A RECENT
070020Z ASCAT PASS SHOWED DIRECTIONAL CONVERGENCE IN THE VICINITY OF
THE DEEPEST CONVECTION VISIBLE ON THE MSI. UPPER LEVEL ANALYSIS
INDICATES AN ANTICYCLONE LOCATED NEAR 9N 155E, IS CREATING A
DIVERGENT UPPER LEVEL PATTERN IN THE VICINITY OF THE LOW LEVEL
CONVERGENCE, AND IS INDUCING THE DEEP CONVECTION IDENTIFIED IN MSI.
MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 10 TO 15 KNOTS.
MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1008 MB. BASED ON
THE LACK OF AN IDENTIFIABLE LOW LEVEL CIRCULATION CENTER AND A
SIGNIFICANT DECREASE IN CONVECTIVE ORGANIZATION OVER THE PAST 24
HOURS, THE POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL
CYCLONE WITHIN THE NEXT 24 HOURS IS DOWNGRADED TO POOR.
