(1) THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 9.4N
127.7E, IS NOW LOCATED NEAR 9.5N 128.0E, APPROXIMATELY 360 NM EAST-
NORTHEAST OF ZAMBOANGA, PHILIPPINES. ANIMATED MULTISPECTRAL
SATELLITE IMAGERY (MSI) DEPICTS A POORLY ORGANIZED AND PARTIALLY
EXPOSED LOW LEVEL CIRCULATION CENTER (LLCC) WITH FLARING DEEP
CONVECTION ALONG THE NORTHERN PERIPHERY. A 170048Z AMSU-B MICROWAVE
IMAGE REVEALS A SHEARED STRUCTURE AS THE LLCC REMAINS LOOSELY
DEFINED DESPITE THE SYSTEM REMAINING OVERALL BROAD AND THE
CONVECTION TO THE NORTH CONTINUES TO BE FRAGMENTED. UPPER-LEVEL
ANALYSIS REVEALS A POOR ENVIRONMENT AS VERTICAL WIND SHEAR IS STRONG
(25 TO 30 KNOTS), WHICH IS OFFSETTING THE HIGHLY DIFFLUENT OUTFLOW.
SEA SURFACE TEMPERATURES IN THE REGION ARE FAVORABLE FOR
DEVELOPMENT. SEE REF A (WTPN21 PGTW 161500) FOR FURTHER DETAILS.
MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 15 TO 20 KNOTS.
MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1007 MB. THE
POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE
WITHIN THE NEXT 24 HOURS REMAINS HIGH.
