(1) THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 10.0N
137.7E, IS NOW LOCATED NEAR 10.0N 137.0E, APPROXIMATELY 215 NM
NORTHEAST OF KOROR, PALAU. ANIMATED MULTISPECTRAL SATELLITE IMAGERY
DEPICTS A CONSOLIDATING LOW LEVEL CIRCULATION CENTER WITH FORMATIVE
CONVECTIVE BANDING ALONG THE SOUTHERN PERIPHERY AND A RECENT BURST
OF CENTRAL CONVECTION. OBSERVATIONS FROM KOROR, PALAU, SHOW 12 KNOT
WESTERLY WINDS AND A 1 MB DROP IN THE PRESSURE TREND OVER THE PAST
24 HOURS. UPPER LEVEL ANALYSIS REVEALS A FAVORABLE ENVIRONMENT WITH
FAIR EQUATORWARD OUTFLOW AND LOW (05 TO 10 KNOTS) VERTICAL WIND
SHEAR. 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 IS UPGRADED TO MEDIUM.
