1) THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 12.0N
138.6E, IS NOW LOCATED NEAR 12.1N 136.7E, APPROXIMATELY 313 NM NORTH-
NORTHEAST OF PALAU. RECENT ENHANCED INFRARED SATELLITE IMAGERY
DEPICTS PERSISTENT DEEP CONVECTION ASSOCIATED WITH A CONSOLIDATING
LOW-LEVEL CIRCULATION CENTER (LLCC). A 080858Z SSMIS MICROWAVE IMAGE
REVEALS TIGHTLY PACKED DEEP CONVECTION WITH FRAGMENTED BANDING
ACROSS THE SOUTHERN AND NORTHERN SEMI-CIRCLES. ADDITIONALLY, FIXING
AGENCIES ARE REPORTING DVORAK CURRENT INTENSITY ESTIMATES RANGING
BETWEEN 1.0 AND 1.5. UPPER LEVEL ANALYSIS INDICATES A FAVORABLE
ENVIRONMENT CHARACTERIZED BY WEAK (5 TO 10 KNOTS) VERTICAL WIND
SHEAR AND STRONG RADIAL OUTFLOW, WHICH IS BEING ENHANCED BY A TUTT
CELL LOCATED TO NORTHWEST OF THE SYSTEM. MAXIMUM SUSTAINED SURFACE
WINDS ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL PRESSURE IS
ESTIMATED TO BE NEAR 1005 MB. THE POTENTIAL FOR THE DEVELOPMENT OF A
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS UPGRADED TO
